    RFT 515: The Evolution of Navigation Jul 09, 2021
    Show notes

    Dead Reckoning On May 21, 1927 Charles Lindbergh landed in Paris, France after a successful non-stop flight from the United States in the single-engined Spirit of St. Louis. As the aircraft was equipped with very basic instruments, Lindbergh used dead reckoning to navigate. Dead reckoning in the air is similar to dead reckoning on the sea, but slightly more complicated. The density of the air the aircraft moves through affects its performance as well as winds, weight, and power settings. The basic formula for DR is Distance = Speed x Time. An aircraft flying at 250 knots airspeed for 2 hours has flown 500 nautical miles through the air. The wind triangle is used to calculate the effects of wind on heading and airspeed to obtain a magnetic heading to steer and the speed over the ground (groundspeed). Printed tables, formulae, or an E6B flight computer are used to calculate the effects of air density on aircraft rate of climb, rate of fuel burn, and airspeed. A course line is drawn on the aeronautical chart along with estimated positions at fixed intervals (say every ½ hour). Visual observations of ground features are used to obtain fixes. By comparing the fix and the estimated position corrections are made to the aircraft's heading and groundspeed. Dead reckoning is on the curriculum for VFR (visual flight rules - or basic level) pilots worldwide. It is taught regardless of whether the aircraft has navigation aids such as GPS, ADF and VOR and is an ICAO Requirement. Many flying training schools will prevent a student from using electronic aids until they have mastered dead reckoning. Inertial navigation systems (INSes), which are nearly universal on more advanced aircraft, use dead reckoning internally. The INS provides reliable navigation capability under virtually any conditions, without the need for external navigation references, although it is still prone to slight errors. Transcontinental Airway System In 1923, the United States Congress funded a sequential lighted airway along the transcontinental airmail route. The lighted airway was proposed by National Advisory Committee for Aeronautics (NACA), and deployed by the Department of Commerce. It was managed by the Bureau of Standards Aeronautical Branch. The first segment built was between Chicago and Cheyenne, Wyoming. It was situated in the middle of the airmail route to enable aircraft to depart from either coast in the daytime, and reach the lighted airway by nightfall. Lighted emergency airfields were also funded along the route every 15–20 miles. Construction pace was fast, and pilots wishing to become airmail pilots were first exposed to the harsh wintertime work with the crews building the first segments of the lighting system. By the end of the year, the public anticipated anchored lighted airways across the Atlantic, Pacific, and to China. The first nighttime airmail flights started on July 1, 1924. By eliminating the transfer of mail to rail cars at night, the coast to coast delivery time for airmail was reduced by two business days. Eventually, there were 284 beacons in service. With a June 1925 deadline, the 2,665 mile lighted airway was completed from New York to San Francisco. In 1927, the lighted airway was complete between New York City and Salt Lake City, Los Angeles to Las Vegas, Los Angeles to San Francisco, New York to Atlanta, and Chicago to Dallas, 4121 miles in total. In 1933, the Transcontinental Airway System totaled 1500 beacons, and 18000 miles. The lighted Airway Beacons were a substantial navigation aid in an era prior to the development of radio navigation. Their effectiveness was limited by visibility and weather conditions.Beacon 61B on a modern display tower, originally installed on route CAM-8 near Castle Rock, WA 24 inches (610 mm) diameter rotating beacons were mounted on 53-foot (16 m) high towers, and spaced ten miles apart. The spacing was closer in the mountains, and farther apart in the plains. The beacons were five million candlepower, and rotated six times a minute. "Ford beacons" (named after Ford Car headlights) were also used, placing four separate lights at different angles.Air ports used green beacons and airways used red beacons. The beacons flashed identification numbers in Morse code. The sequence was "WUVHRKDBGM", which prompted the mnemonic "When Undertaking Very Hard Routes Keep Directions By Good Methods".Engineers believed the variations of beacon height along hills and valleys would allow pilots to see beacons both above ground fog, and below cloud layers. Towers were built of numbered angle iron sections with concrete footings. Some facilities used concrete arrows pointing in the direction of towers. In areas where no connection to a power grid was available, a generator was housed in a small building. Some buildings also served as weather stations. Many arrow markings were removed during World War II, to prevent aiding enemy bombers in navigation, while 19 updated beacons still remain in service in Montana. ADF An automatic direction finder (ADF) is a marine or aircraft radio-navigation instrument that automatically and continuously displays the relative bearing from the ship or aircraft to a suitable radio station. ADF receivers are normally tuned to aviation or marine NDBs (Non-Directional Beacon) operating in the LW band between 190 – 535 kHz. Like RDF (Radio Direction Finder) units, most ADF receivers can also receive medium wave (AM) broadcast stations, though as mentioned, these are less reliable for navigational purposes. The operator tunes the ADF receiver to the correct frequency and verifies the identity of the beacon by listening to the Morse code signal transmitted by the NDB. On marine ADF receivers, the motorized ferrite-bar antenna atop the unit (or remotely mounted on the masthead) would rotate and lock when reaching the null of the desired station. A centerline on the antenna unit moving atop a compass rose indicated in degrees the bearing of the station. On aviation ADFs, the unit automatically moves a compass-like pointer (RMI) to show the direction of the beacon. The pilot may use this pointer to home directly towards the beacon, or may also use the magnetic compass and calculate the direction from the beacon (the radial) at which their aircraft is located. Unlike the RDF, the ADF operates without direct intervention, and continuously displays the direction of the tuned beacon. Initially, all ADF receivers, both marine and aircraft versions, contained a rotating loop or ferrite loopstick aerial driven by a motor which was controlled by the receiver. Like the RDF, a sense antenna verified the correct direction from its 180-degree opposite. More modern aviation ADFs contain a small array of fixed aerials and use electronic sensors to deduce the direction using the strength and phase of the signals from each aerial. The electronic sensors listen for the trough that occurs when the antenna is at right angles to the signal, and provide the heading to the station using a direction indicator. In flight, the ADF's RMI or direction indicator will always point to the broadcast station regardless of aircraft heading. Dip error is introduced, however, when the aircraft is in a banked attitude, as the needle dips down in the direction of the turn. This is the result of the loop itself banking with the aircraft and therefore being at a different angle to the beacon. For ease of visualisation, it can be useful to consider a 90° banked turn, with the wings vertical. The bearing of the beacon as seen from the ADF aerial will now be unrelated to the direction of the aircraft to the beacon. VOR Very high frequency omni-directional range (VOR) is a type of short-range radio navigation system for aircraft, enabling aircraft with a receiving unit to determine its position and stay on course by receiving radio signals transmitted by a network of fixed ground radio beacons. It uses frequencies in the very high frequency (VHF) band from 108.00 to 117.95 MHz. Developed in the United States beginning in 1937 and deployed by 1946, VOR is the standard air navigational system in the world, used by both commercial and general aviation. In the year 2000 there were about 3,000 VOR stations operating around the world, including 1,033 in the US, reduced to 967 by 2013 (stations are being decommissioned with widespread adoption of GPS). A VOR ground station uses a phased antenna array to send a highly directional signal that rotates clockwise horizontally (as seen from above) 30 times a second. It also sends a 30 Hz reference signal on a subcarrier timed to be in phase with the directional antenna as the latter passes magnetic north. This reference signal is the same in all directions. The phase difference between the reference signal and the signal amplitude is the bearing from the VOR station to the receiver relative to magnetic north. This line of position is called the VOR "radial". The intersection of radials from two different VOR stations can be used to fix the position of the aircraft, as in earlier radio direction finding (RDF) systems. VOR stations are fairly short range: the signals are line-of-sight between transmitter and receiver and are useful for up to 200 miles. Each station broadcasts a VHF radio composite signal including the navigation signal, station's identifier and voice, if so equipped. The navigation signal allows the airborne receiving equipment to determine a bearing from the station to the aircraft (direction from the VOR station in relation to Magnetic North). The station's identifier is typically a three-letter string in Morse code. The voice signal, if used, is usually the station name, in-flight recorded advisories, or live flight service broadcasts. Area Navigation The continuing growth of aviation increases demands on airspace capacity, making area navigation desirable due to its improved operational efficiency. RNAV systems evolved in a manner similar to conventional ground-based routes and procedures. A specific RNAV system was identified and its performance was evaluated through a combination of analysis and flight testing. For land-based operations, the initial systems used very high frequency omnidirectional radio range (VOR) and distance measuring equipment (DME) for estimating position; for oceanic operations, inertial navigation systems (INS) were employed. Airspace and obstacle clearance criteria were developed based on the performance of available equipment, and specifications for requirements were based on available capabilities. Such prescriptive requirements resulted in delays to the introduction of new RNAV system capabilities and higher costs for maintaining appropriate certification. To avoid such prescriptive specifications of requirements, an alternative method for defining equipment requirements has been introduced. This enables the specification of performance requirements, independent of available equipment capabilities, and is termed performance-based navigation (PBN). Thus, RNAV is now one of the navigation techniques of PBN; currently the only other is required navigation performance (RNP). RNP systems add on-board performance monitoring and alerting to the navigation capabilities of RNAV. As a result of decisions made in the industry in the 1990s, most modern systems are RNP. Many RNAV systems, while offering very high accuracy and possessing many of the functions provided by RNP systems, are not able to provide assurance of their performance. Recognising this, and to avoid operators incurring unnecessary expense, where the airspace requirement does not necessitate the use of an RNP system, many new as well as existing navigation requirements will continue to specify RNAV rather than RNP systems. It is therefore expected that RNAV and RNP operations will co-exist for many years. However, RNP systems provide improvements in the integrity of operation, permitting possibly closer route spacing, and can provide sufficient integrity to allow only the RNP systems to be used for navigation in a specific airspace. The use of RNP systems may therefore offer significant safety, operational and efficiency benefits. While RNAV and RNP applications will co-exist for a number of years, it is expected that there will be a gradual transition to RNP applications as the proportion of aircraft equipped with RNP systems increases and the cost of transition reduces. INS Inertial navigation is a self-contained navigation technique in which measurements provided by accelerometers and gyroscopes are used to track the position and orientation of an object relative to a known starting point, orientation and velocity. Inertial measurement units (IMUs) typically contain three orthogonal rate-gyroscopes and three orthogonal accelerometers, measuring angular velocity and linear acceleration respectively. By processing signals from these devices it is possible to track the position and orientation of a device. Inertial navigation is used in a wide range of applications including the navigation of aircraft, tactical and strategic missiles, spacecraft, submarines and ships. It is also embedded in some mobile phones for purposes of mobile phone location and tracking Recent advances in the construction of microelectromechanical systems (MEMS) have made it possible to manufacture small and light inertial navigation systems. These advances have widened the range of possible applications to include areas such as human and animal motion capture. An inertial navigation system includes at least a computer and a platform or module containing accelerometers, gyroscopes, or other motion-sensing devices. The INS is initially provided with its position and velocity from another source (a human operator, a GPS satellite receiver, etc.) accompanied with the initial orientation and thereafter computes its own updated position and velocity by integrating information received from the motion sensors. The advantage of an INS is that it requires no external references in order to determine its position, orientation, or velocity once it has been initialized. An INS can detect a change in its geographic position (a move east or north, for example), a change in its velocity (speed and direction of movement) and a change in its orientation (rotation about an axis). It does this by measuring the linear acceleration and angular velocity applied to the system. Since it requires no external reference (after initialization), it is immune to jamming and deception. Inertial navigation systems are used in many different moving objects. However, their cost and complexity place constraints on the environments in which they are practical for use. Gyroscopes measure the angular velocity of the sensor frame with respect to the inertial reference frame. By using the original orientation of the system in the inertial reference frame as the initial condition and integrating the angular velocity, the system's current orientation is known at all times. This can be thought of as the ability of a blindfolded passenger in a car to feel the car turn left and right or tilt up and down as the car ascends or descends hills. Based on this information alone, the passenger knows what direction the car is facing but not how fast or slow it is moving, or whether it is sliding sideways. Accelerometers measure the linear acceleration of the moving vehicle in the sensor or body frame, but in directions that can only be measured relative to the moving system (since the accelerometers are fixed to the system and rotate with the system, but are not aware of their own orientation). This can be thought of as the ability of a blindfolded passenger in a car to feel himself pressed back into his seat as the vehicle accelerates forward or pulled forward as it slows down; and feel himself pressed down into his seat as the vehicle accelerates up a hill or rise up out of t…

    Brushy Four

    On 1 July 1972 I was number 4 in Brushy Flight, attacking a target in Kep, North Vietnam. As we exited the target area, our flight was targeted by a Surface-to-Air Missile (SAM) from our left 7 o'clock position. This SAM was tracking differently than a typical SA-2. The typical SA-2 traveled in a lead-pursuit flight path, not too difficult to defeat if you can see it. this SAM was different. It was traveling in a lag-pursuit flight path, aiming directly at out flight.

    We separated into two sections of two aircraft, about 1000 feet apart, with each wingman flying in close formation with his lead aircraft. As number 4, I flew in formation on the left wing with Brushy 3, the deputy flight lead. I watched the missile track toward our section in my left rear-view mirror. It was heading directly for me. As it was about to hit me, I flinched to the left and was immediately rocked by the sound of the explosion as it hit Brushy 3.

    Fortunately, Brushy 3 did not go down. The missile detonated as a proximity burst. His aircraft was leaking fluids, but continued to fly. Because he had lost his utility hydraulic system Brushy 3 could not refuel, so he would have to land at DaNang, South Vietnam, if his fuel supply lasted. I was assigned to escort him to DaNang. Miraculously, his fuel supply lasted, and he landed with an approach-end engagement on runway 17 left while I landed on runway 17 right.

    After refueling, I led another F-4 in formation back to Ubon. The reason I led the flight, at low altitude, was because the other aircraft could not pressurize. It had taken a small arms round through the rear canopy, right through the back-seater's heart.

    Walnut Four

    The Vietnam Veterans Memorial – The Wall – has panels that list the KIA (Killed In Action) casualties in chronological order of their loss. Panel W1, the last panel, encompasses the date July 30, 1972. My name is not on that panel, because my military Brothers, Sid Fulgham, J.D. Allen and the crew of Purple 28, saved my life.

    I was Number Four in Walnut Flight, four F-4s on a strike deep into enemy territory north of Hanoi. The flight was being led by our new squadron commander, Sid Fugham, on his first mission leading a strike over Hanoi, and J.D. was the deputy flight lead, Walnut Three. Enroute to the target, we faced heavy reactions. SAMs (surface-to-air missiles), AAA (anti-aircraft artillery) and MiG calls (enemy aircraft). As we egressed the target area over the Gulf of Tonkin, Lead called for a fuel check, and that was when we all realized that my fuel was significantly below the other airplanes in the flight. In fact, I wouldn’t have enough fuel to make it to the post-strike refueling point.

    Sid was out of ideas, and that’s when J.D. went into action. With Sid’s concurrence, J.D. took command of the flight, sent us over to the emergency GUARD frequency, and made contact with the refueling tankers. One of them, Purple 28, volunteered to fly up into enemy territory to meet us. That crew put their airplane, their lives, and their careers on the line to save me.

    Back in 1972, navigation was not the GPS precision it is today. The INS (inertial navigation system) position on the F-4 could be off by as much as 10 miles for every hour of operation. The only way to roughly determine our position was radial/DME from a TACAN located on a Navy ship, far away. J.D. asked the tanker for his position from the TACAN, then gave the tanker a heading to meet up with us. Picking the tanker up on radar, J.D. told him when to begin his turn to a heading to match ours, and told him to start a descent. In the meantime, he directed me to start a half-nozzle descent.

    My WSO and I were running through the Preparation For Ejection checklist, and I was periodically reporting my fuel state. The last reading I recall seeing was 0 on the tape and 0030 on the counter. About two minutes fuel. With fuel gauge tolerance, perhaps a bit more, perhaps less.

    Up until this time I had simply been flying the headings, speeds and altitudes J.D. had assigned. I was pretty much operating on mental autopilot. The next thing I knew, I looked up and saw the refueling boom of the tanker directly above me, flying a "toboggan maneuver". I opened up my refueling door and immediately heard the rush of JP-4 entering my aircraft. And I knew I wouldn’t need to step over the side on this mission.

    I think of J.D. and the tanker crew, and silently thank them, every time I hold my wife, my kids, my grandkids. If they hadn’t stepped up to the plate when they did, I’m fairly certain I wouldn’t have made it home. When you pull the ejection handle over shark-infested enemy-controlled water, there are a thousand things that can happen to prevent a happy outcome.

    So on this coming July 30th, I want to once again thank my Brothers, the brave tanker crew, Sid Fulgham, and J.D. Allen.

    My Last F-4 Flight

    In 1973 I was assigned to the 44th Tactical Fighter Squadron, at Kadena Air Base, in Okinawa. The squadron was on long-term TDY to CCK Air Base, in Taiwan. I was going through squadron check-out in the F-4C, and had flown a gunnery mission to Ie Shima bombing range in Okinawa.

    For several weeks before July 5th I had been feeling unusually tired. I still ran five miles every day, and put in a lot of hours at the squadron on my additional duties as Life Support Officer, as well as filling in for the Admin Officer, who was TDY. But, naturally, as a self-designated Iron Man, I didn't check in with a flight surgeon.

    On this flight, I was feeling really, really weak. During the pitch-out during our arrival back at the base, I was blacking out from two Gs! After we taxied in to park, I couldn't climb out of the airplane by myself, and an ambulance crew took me to the hospital. Turned out I had Mononucleosis.

    After I was released from the hospital, I was placed on non-flying duties for several months, and during that time I was reassigned to Wing Headquarters in a desk job. Although I continued to fly after I recovered, it was in the T-39 Sabreliner, not the F-4. So I never had the closure of a "champagne flight" in the F-4.


    RFT 513: MOH Steven Bennett Story Jul 01, 2021
    Show notes

    On June 29, the second day of the counteroffensive, an OV-10 flown by Air Force Capt. Steven L. Bennett had been working through the afternoon in the area south and east of Quang Tri City. Bennett, 26, was born in Texas but grew up in Lafayette, La. He was commissioned via ROTC in 1968 at the University of Southwestern Louisiana. After pilot training, he had flown B-52s as a copilot at Fairchild AFB, Wash. He also had pulled five months of temporary duty in B-52s at U Tapao in Thailand. After that, he volunteered for a combat tour in OV-10s and had arrived at Da Nang in April 1972. Bennett’s partner in the backseat of the OV-10 on June 29 was Capt. Michael B. Brown, a Marine Corps airborne artillery observer and also a Texan. Brown, a company commander stationed in Hawaii, had volunteered for a 90-day tour in Vietnam spotting for naval gunners from the backseat of an OV-10. Air Force FACs were not trained in directing the fire of naval guns. The two had flown together several times before on artillery adjustment missions. They had separate call signs. Bennett’s was “Covey 87.” Brown was “Wolfman 45.” They took off from Da Nang at about 3 p.m. During the time they were airborne, Brown had been directing fire from the destroyer USS R.B. Anderson and the cruiser USS Newport News, which were about a mile offshore in the Tonkin Gulf. Bennett and Brown had also worked two close air support strikes by Navy fighters. It was almost time to return to base, but their relief was late taking off from Da Nang, so Bennett and Brown stayed a little longer. The area in which they were flying that afternoon had been fought over many times before. French military forces, who took heavy casualties here in the 1950s, called the stretch of Route 1 between Quang Tri and Hue the “Street Without Joy.” US airmen called it “SAM-7 Alley.” SA-7s were thick on the ground there, and they had taken a deadly toll on low-flying airplanes. The SA-7 could be carried by one man. It was similar to the US Redeye. It was fired from the shoulder like a bazooka, and its warhead homed on any source of heat, such as an aircraft engine. Pilots could outrun or outmaneuver the SA-7—if they saw it in time. At low altitudes, that was seldom possible. “Before the SA-7, the FACs mostly flew at 1,500 to 4,500 feet,” said William J. Begert, who, in 1972, was a captain and an O-2 pilot at Da Nang. “After the SA-7, it was 9,500 feet minimum. You could sneak an O-2 down to 6,500, but not an OV-10, because the bigger engines on OV-10 generated more heat.” The FACs sometimes carried flares on their wings and could fire them as decoys when they saw a SA-7 launch. “The problem was reaction time,” Begert said. “You seldom got the flare off before the missile had passed.” About 6 p.m., Bennett and Brown got an emergency call from “Harmony X-ray,” a US Marine Corps ground artillery spotter with a platoon of South Vietnamese marines a few miles east of Quang Tri City. The platoon consisted of about two dozen troops. They were at the fork of a creek, with several hundred North Vietnamese Army regulars advancing toward them. The NVA force was supported by big 130 mm guns, firing from 12 miles to the north at Dong Ha, as well as by smaller artillery closer by. Without help, the South Vietnamese marines would soon be overrun. Bennett called for tactical air support, but no fighters were available. The guns from Anderson and Newport News were not a solution, either. “The ships were about a mile offshore, and the friendlies were between the bad guys and the ships,” Brown said. “Naval gunfire shoots flat, and it has a long spread on impact. There was about a 50-50 chance they’d hit the friendlies.” Bennett decided to attack with the OV-10’s four 7.62 mm guns. That meant he would have to descend from a relatively safe altitude and put his aircraft within range of SA-7s and small-arms fire. Because of the risk, Bennett was required to call for permission first. He did and got approval to go ahead. Apart from its employment as a FAC aircraft, the OV-10 was rated for a light ground attack role. Its machine guns were loaded with 500 rounds each. The guns were mounted in the aircraft’s sponsons, stubby wings that stuck out like a seal’s flippers from the lower fuselage. Bennett put the OV-10 into a power dive. The NVA force had been gathering in the trees along the creek bank. As Bennett roared by, the fire from his guns scattered the enemy concentration. After four strafing passes, the NVA began to retreat, leaving many dead and wounded behind. The OV-10 had taken a few hits in the fuselage from small-arms fire but nothing serious. Bennett decided to continue the attack to keep the NVA from regrouping and to allow the South Vietnamese to move to a more tenable position. Bennett swept along the creek for a fifth time and pulled out to the northeast. He was at 2,000 feet, banking to turn left, when the SA-7 hit from behind. Neither Bennett nor Brown saw it. The missile hit the left engine and exploded. The aircraft reeled from the impact. Shrapnel tore holes in the canopy. Much of the left engine was gone. The left landing gear was hanging down like a lame leg, and they were afire. Bennett needed to jettison the reserve fuel tank and the remaining smoke rockets as soon as he could, but there were South Vietnamese troops everywhere below. He headed for the Tonkin Gulf, hoping to get there and drop the stores before the fire reached the fuel. As they went, Brown radioed their Mayday to declare the emergency. Over the Gulf, Bennett safely dropped the fuel tank and rocket pods. The OV-10 was still flyable on one engine, although it could not gain altitude. They turned south, flying at 600 feet. Unless Bennett could reach a friendly airfield for an emergency landing, he and Brown would have to either eject or ditch the airplane in the Gulf of Tonkin. Every OV-10 pilot knew the danger of ditching. The aircraft had superb visibility because of the “greenhouse”-style expanses of plexiglass canopy in front and on the sides, but that came at the cost of structural strength. It was common knowledge, often discussed in the squadron, that no pilot had ever survived an OV-10 ditching. The cockpit always broke up on impact. Another OV-10 pilot, escorting Bennett’s aircraft, warned him to eject as the wing was in danger of exploding. They began preparations to eject. As they did, Brown looked over his shoulder at the spot where his parachute should have been. “What I saw was a hole, about a foot square, from the rocket blast and bits of my parachute shredded up and down the cargo bay,” Brown said. “I told Steve I couldn’t jump.” Bennett would not eject alone. That would have left Brown in an airplane without a pilot. Besides, the backseater had to eject first. If not, he would be burned severely by the rocket motors on the pilot’s ejection seat as it went out. Momentarily, there was hope. The fire subsided. Da Nang—the nearest runway that could be foamed down—was only 25 minutes away and they had the fuel to get there. Then, just north of Hue, the fire fanned up again and started to spread. The aircraft was dangerously close to exploding. They couldn’t make it to Da Nang. Bennett couldn’t eject without killing Brown. That left only one choice: to crash-land in the sea. Bennett faced a decision, Lt. Col. Gabriel A. Kardong, 20th TASS commander, later wrote in recommending Bennett for the Medal of Honor. “He knew that if he saved his own life by ejecting from his aircraft, Captain Brown would face certain death,” said Kardong. “On the other hand, he realized that if he ditched the aircraft, his odds for survival were slim, due to the characteristics of the aircraft, but Captain Brown could survive. Captain Bennett made the decision to ditch and thereby made the ultimate sacrifice.” He decided to ditch about a mile off a strip of sand called “Wunder Beach.” Upon touchdown, the dangling landing gear dug in hard. “When the aircraft struck water, the damaged and extended left landing gear caused the aircraft to swerve left and flip wing over wing and come to rest in a nose down and inverted position, almost totally submerged,” Brown said in a statement attached to the Medal of Honor recommendation. “After a struggle with my harnesses, I managed to escape to the surface where I took a few deep breaths of air and attempted to dive below the surface in search of the pilot who had not surfaced. Exhaustion and ingestion of fuel and water prevented me from descending below water more than a few feet. I was shortly rescued by an orbiting naval helicopter and taken to the USS Tripoli for treatment.” Of Bennett, Brown said, “His personal disregard for his own life surely saved mine when he elected not to eject … and save himself in order that I might survive.” Bennett’s body was recovered the next day. The front cockpit had broken up on impact with the water, and it had been impossible for him to get out. He was taken home to Lafayette, where he is buried. North Vietnam’s Easter Offensive, battered by airpower, stalled. The South Vietnamese retook Quang Tri City on Sept. 16, 1972. The invasion having failed, Giap was forced to withdraw on all three fronts. It was a costly excursion for North Vietnam, with 100,000 or more of its troops killed and at least half of its tanks and large-caliber artillery pieces having been lost. The Medal of Honor was awarded posthumously to Steven L. Bennett on Aug. 8, 1974. It was presented in Washington to his wife, Linda, and their daughter Angela, two-and-a- half years old, by Vice President Gerald R. Ford in the name of Congress. (Ford made the presentation because President Nixon announced his resignation that day. Ford was sworn in as President the next day, Aug. 9, 1974.) The citation accompanying the Medal of Honor recognized “Captain Bennett’s unparalleled concern for his companion, extraordinary heroism, and intrepidity above and beyond the call of duty, at the cost of his life.” Since then, there have been other honors. Navy Sealift Command named a ship MV Steven L. Bennett. Palestine, Tex., where Bennett was born, dedicated the city athletic center to him. Among other facilities named for or dedicated to Bennett were the ROTC building at the University of Southwestern Louisiana, the gymnasium at Kelly AFB, Tex., and a cafeteria at Webb AFB, Tex. From Wiki.org: Steven Logan Bennett (April 22, 1946 – June 29, 1972) of Palestine, Texas was a United States Air Force pilot who posthumously received the Medal of Honor for heroism during the Vietnam War on August 8, 1974 Prior to entering the U.S. Air Force, Steven Bennett attended the University of Southwestern Louisiana (now University of Louisiana at Lafayette) in Lafayette, Louisiana; he graduated with a degree in Aerospace Engineering. He was in ROTC and received his private pilot's license in 1965. He entered the Air Force in August 1968, and earned his pilot wings at Webb AFB, Texas in 1969. In 1970, he completed B-52 bomber training course at Castle AFB, CA. He was stationed at Fairchild AFB, Washington. He flew B-52s out of Thailand for almost a year. He then transitioned to become a Forward Air Controller (FAC), and graduated from the FAC and fighter training courses at Cannon AFB, New Mexico, before reporting to Da Nang, Vietnam in April 1972. He had only been in combat for three months before his Medal of Honor mission and had also won the Air Medal with three oak leaf clusters. He was also awarded the Purple Heart and the Cheny Award. His call-sign at DaNang was Covey 87. Bennett had recently turned 26 when he was killed. Captain Bennett was posthumously awarded the Medal of Honor. Vice President Gerald Ford presented the decoration to Captain Bennett’s wife, Linda, and daughter, Angela, at the Blair House on August 8, 1974. Bennett is buried in Lafayette Memorial Cemetery at Lafayette, Louisiana. He was survived by his wife and one child. He had two brothers, David and Miles, and three sisters, Kathe, Lynne and Ardra. His mother, Edith Alice Logan Bennett, preceded him in death and his father, Elwin Bennett, died many years later in 2006. His daughter now lives near Dallas, TX with her husband, Paul, and two children, Jake and Elizabeth. His wife, Linda Leveque Bennett Wells, died on July 11, 2011. Bennett's observer, Mike Brown, and was reunited with Bennett's wife and daughter in 1988. They have since remained close and together have attended numerous dedications in Bennett's honor throughout the United States. Angela is a lifetime member of the OV-10 Association located at Meacham Air Field in Fort Worth, Texas. They have acquired an OV-10 and painted the names of both Bennett and Mike Brown on the side in memory of their last flight together. Angela was named by her father, who chose Angela Noelle, as in Christmas Angel; she was born near Christmas. He is the namesake of the ship MV Capt. Steven L. Bennett (T-AK-4296) and his name is engraved on the Vietnam Memorial at Panel 01W - Row 051. There have been numerous other dedications done in his honor. They range from streets being named after him to buildings, including a gymnasium and a cafeteria, a sports arena and VFW posts, and many monuments. He has been mentioned in several military history books. Medal of Honor citation The President of the United States takes pride in presenting the MEDAL OF HONOR posthumously to CAPTAIN STEVEN L. BENNETT UNITED STATES AIR FORCE 20th Tactical Air Support Squadron, Pacific Air Forces. Place and date of action: Quang Tri, Republic of Vietnam, June 29, 1972. For service as set forth in the following Citation: Capt. Bennett was the pilot of a light aircraft flying an artillery adjustment mission along a heavily defended segment of route structure. A large concentration of enemy troops was massing for an attack on a friendly unit. Capt. Bennett requested tactical air support but was advised that none was available. He also requested artillery support but this too was denied due to the close proximity of friendly troops to the target. Capt. Bennett was determined to aid the endangered unit and elected to strafe the hostile positions. After 4 such passes, the enemy force began to retreat. Capt. Bennett continued the attack, but, as he completed his fifth strafing pass, his aircraft was struck by a surface-to-air missile, which severely damaged the left engine and the left main landing gear. As fire spread in the left engine, Capt. Bennett realized that recovery at a friendly airfield was impossible. He instructed his observer to prepare for an ejection, but was informed by the observer that his parachute had been shredded by the force of the impacting missile. Although Capt. Bennett had a good parachute, he knew that if he ejected, the observer would have no chance of survival. With complete disregard for his own life, Capt. Bennett elected to ditch the aircraft into the Gulf of Tonkin, even though he realized that a pilot of this type aircraft had never survived a ditching. The ensuing impact upon the water caused the aircraft to cartwheel and severely damaged the front cockpit, making escape for Capt. Bennett impossible. The observer successfully made his way out of the aircraft and was rescued. Capt. Bennett's unparalleled concern for his companion, extraordinary heroism and intrepidity above and beyond the call of duty, at the cost of his life, were in keeping with the highest traditions of the military service and reflect great credit upon himself and the U.S. Air Force.

    RFT 511: Approach Lights Jun 24, 2021
    Show notes

    An approach lighting system (ALS) is a lighting system installed on the approach end of an airport runway and consisting of a series of lightbars, strobe lights, or a combination of the two that extends outward from the runway end. ALS usually serves a runway that has an instrument approach procedure (IAP) associated with it and allows the pilot to visually identify the runway environment and align the aircraft with the runway upon arriving at a prescribed point on an approach.

    Modern approach lighting systems are highly complex in their design and significantly enhance the safety of aircraft operations, particularly in conditions of reduced visibility.

    The required minimum visibilities for instrument approaches is influenced by the presence and type of approach lighting system. In the U.S., a CAT I ILS approach without approach lights will have a minimum required visibility of 3/4 mile, or 4000 foot runway visual range. With a 1400-foot or longer approach light system, the minimum potential visibility might be reduced to 1/2 mile (2400 runway visual range), and the presence of touchdown zone and centerline lights with a suitable approach light system might further reduce the visibility to 3/8 mile (1800 feet runway visual range).

    The runway lighting is controlled by the air traffic control tower. At non-towered airports, pilot-controlled lighting may be installed that can be switched on by the pilot via radio. In both cases, the brightness of the lights can be adjusted for day and night operations.

    Depth perception is inoperative at the distances usually involved in flying aircraft, and so the position and distance of a runway with respect to an aircraft must be judged by a pilot using only two-dimensional cues such as perspective, as well as angular size and movement within the visual field. Approach lighting systems provide additional cues that bear a known relationship to the runway itself and help pilots to judge distance and alignment for landing.

    After World War II, the U.S. Navy and United Airlines worked together on various methods at the U.S. Navy's Landing Aids Experimental Station located at the Arcata–Eureka Airport, California air base, to allow aircraft to land safely at night and under zero visibility weather, whether it was rain or heavy fog. The predecessor of today's modern ALS while crude had the basics — a 3,500 foot visual approach of 38 towers, with 17 on each side, and atop each 75 foot high tower a 5000 watt natural gas light. After the U.S. Navy's development of the lighted towers it was not long before the natural gas lights were soon replaced by more efficient and brighter strobe lights, then called Strobeacon lights. The first large commercial airport to have installed a strobe light ALS visual approach path was New York City's John F. Kennedy International Airport. Soon other large airports had strobe light ALS systems installed.

    All approach lighting systems in the United States utilize a feature called a decision bar. Decision bars are always located 1000′ farther away from the threshold in the direction of the arriving aircraft, and serve as a visible horizon to ease the transition from instrument flight to visual flight.

    Approach lighting systems are designed to allow the pilot to quickly and positively identify visibility distances in Instrument meteorological conditions. For example, if the aircraft is at the middle marker, and the middle marker is located 3600 feet from the threshold, the decision bar is 2600 feet ahead. If the procedure calls for at least half a statute mile flight visibility (roughly 2600 feet), spotting the decision bar at the marker would indicate enough flight visibility to continue the procedure. In addition, the shorter bars before and after the decision bar are spaced either 100 feet or 200 feet apart, depending on the ALS type. The number of short bars the pilot can see can be used to determine flight visibility. Approaches with lower minimums use the more precise 100-foot spacing systems for more accurate identification of visibility.

    Several ALS configurations are recognized by the International Civil Aviation Organization (ICAO); however, non-standard ALS configurations are installed at some airports. Typically, approach lighting systems are of high-intensity. Many approach lighting systems are also complemented by various on-runway light systems, such as Runway end identifier lights (REIL), Touchdown Zone Lights (TDZL), and High Intensity Runway Lights (HIRL). The most common approach light system configurations include:

    • MALSR: Medium-intensity Approach Lighting System with Runway Alignment Indicator Lights
    • MALSF: Medium-intensity Approach Lighting System with Sequenced Flashing lights
    • SALS: Short Approach Lighting System
    • SSALS: Simplified Short Approach Lighting System
    • SSALR: Simplified Short Approach Lighting System with Runway Alignment Indicator Lights
    • SSALF: Simplified Short Approach Lighting System with Sequenced Flashing Lights
    • ODALS: Omnidirectional Approach Lighting System
    • ALSF-1: Approach Lighting System with Sequenced Flashing Lights configuration 1
    • ALSF-2: Approach Lighting System with Sequenced Flashing Lights configuration 2
    • CALVERT I/ICAO-1 HIALS: ICAO-compliant configuration 1 High Intensity Approach Lighting System
    • CALVERT II/ICAO-2 HIALS: ICAO-compliant configuration 2 High Intensity Approach Lighting System
    • LDIN: Lead-in lighting
    • REIL: Runway End Identification Lights
    • RAIL: Runway Alignment Indicator Lights

    In configurations that include sequenced flashing lights, the lights are typically strobes mounted in front of the runway on its extended centerline. These lights flash in sequence, usually at a speed of two consecutive sequences per second, beginning with the light most distant from the runway and ending at the Decision Bar. RAIL are similar to sequenced flashing lights, except that they end where the white approach light bars begin. Sequenced flashing lights and RAIL do not extend past the Decision Bar to avoid distracting the pilot during the critical phase of transitioning from instrument to visual flight. Sequenced flashing lights are sometimes colloquially called the rabbit or the running rabbit.


    RFT 510: Remembering Morris Nolly on Father's Day Jun 20, 2021
    Show notes

    On this Father's Day I want to honor my father, Morris Nolly. He was the reason I became a pilot.

    Morris Nolly was a first-generation American, the fourth of five children born to Russian immigrants Wolf and Tillie Noloboff in 1909. He grew up in Brooklyn, NY. Speaking only Yiddish at home, he didn't learn English until he entered grade school. He excelled in his studies, and received a full scholarship to New York University, where he studied Aircraft and Navigation Instruments, and he graduated from Cooper Union College with a degree in Electrical Engineering.

    Finding money for flight training was a challenge during the Depression, but he periodically took lessons in a J-3 Cub starting in 1935, and eventually earned his Private Pilot certificate in 1941. His logbook originally had the name Noloboff, but was changed to Nolly when Morris officially changed his name.

    As an Electrical Engineer, he designed the entire lighting system at the Aquacade at the 1939 World's Fair in New York, and then was hired by DuPont Company in Wilmington, Delaware. A fellow employee introduced him to his niece, Rose Dworkin, and it was love at first sight. They married shortly before the attack on Pearl Harbor.

    Morris enlisted in the Army Air Force and was assigned as a Research Engineer, stationed at Wright Field (now Wright-Patterson Air Force Base) in Dayton, OH, where he specialized in airfield lighting systems and photographic lighting. During his free time he taught himself gymnastics and had success as an amateur boxer. While in the Army, he filed his invention for the precursor to Inertial Navigation System (see below).

    After the war he bought a J-3 Cub and continued his flight training, eventually earning his Commercial Pilot certificate with an Instrument Rating. Then, when he was laid off from DuPont, he sold the airplane and went into business for himself as the proprietor of a liquor store. He renewed his flying with the Civil Air Patrol, where he served as a Major.

    Morris taught himself Morse Code and was active in "ham" radio, using the call sign W3FZM. He used his ham radio to summon emergency response forces when a bonanza disintegrated in flight over his house on April 28, 1955. The pilot, Floyd Quillen, was Morris's friend.

    Father's Day 1960 was a special day. We spent the day on the Chesapeake Bay, and posed for a photo to see who had a bigger nose. It was the culmination of a time period when Dad and I had been especially close.

    Two days later Dad was killed during a robbery of the family store. He was 50 years old.


    RFT 509: Inertial Navigation Systems Jun 17, 2021
    Show notes

    Inertial navigation is a self-contained navigation technique in which measurements provided by accelerometers and gyroscopes are used to track the position and orientation of an object relative to a known starting point, orientation and velocity. Inertial measurement units (IMUs) typically contain three orthogonal rate-gyroscopes and three orthogonal accelerometers, measuring angular velocity and linear acceleration respectively. By processing signals from these devices it is possible to track the position and orientation of a device.

    Inertial navigation is used in a wide range of applications including the navigation of aircraft, tactical and strategic missiles, spacecraft, submarines and ships. It is also embedded in some mobile phones for purposes of mobile phone location and tracking Recent advances in the construction of microelectromechanical systems (MEMS) have made it possible to manufacture small and light inertial navigation systems. These advances have widened the range of possible applications to include areas such as human and animal motion capture.

    An inertial navigation system includes at least a computer and a platform or module containing accelerometers, gyroscopes, or other motion-sensing devices. The INS is initially provided with its position and velocity from another source (a human operator, a GPS satellite receiver, etc.) accompanied with the initial orientation and thereafter computes its own updated position and velocity by integrating information received from the motion sensors. The advantage of an INS is that it requires no external references in order to determine its position, orientation, or velocity once it has been initialized.

    An INS can detect a change in its geographic position (a move east or north, for example), a change in its velocity (speed and direction of movement) and a change in its orientation (rotation about an axis). It does this by measuring the linear acceleration and angular velocity applied to the system. Since it requires no external reference (after initialization), it is immune to jamming and deception.

    Inertial navigation systems are used in many different moving objects. However, their cost and complexity place constraints on the environments in which they are practical for use.

    Gyroscopes measure the angular velocity of the sensor frame with respect to the inertial reference frame. By using the original orientation of the system in the inertial reference frame as the initial condition and integrating the angular velocity, the system's current orientation is known at all times. This can be thought of as the ability of a blindfolded passenger in a car to feel the car turn left and right or tilt up and down as the car ascends or descends hills. Based on this information alone, the passenger knows what direction the car is facing but not how fast or slow it is moving, or whether it is sliding sideways.

    Accelerometers measure the linear acceleration of the moving vehicle in the sensor or body frame, but in directions that can only be measured relative to the moving system (since the accelerometers are fixed to the system and rotate with the system, but are not aware of their own orientation). This can be thought of as the ability of a blindfolded passenger in a car to feel himself pressed back into his seat as the vehicle accelerates forward or pulled forward as it slows down; and feel himself pressed down into his seat as the vehicle accelerates up a hill or rise up out of their seat as the car passes over the crest of a hill and begins to descend. Based on this information alone, he knows how the vehicle is accelerating relative to itself, that is, whether it is accelerating forward, backward, left, right, up (toward the car's ceiling), or down (toward the car's floor) measured relative to the car, but not the direction relative to the Earth, since he did not know what direction the car was facing relative to the Earth when they felt the accelerations.

    However, by tracking both the current angular velocity of the system and the current linear acceleration of the system measured relative to the moving system, it is possible to determine the linear acceleration of the system in the inertial reference frame. Performing integration on the inertial accelerations (using the original velocity as the initial conditions) using the correct kinematic equations yields the inertial velocities of the system and integration again (using the original position as the initial condition) yields the inertial position. In our example, if the blindfolded passenger knew how the car was pointed and what its velocity was before he was blindfolded and if he is able to keep track of both how the car has turned and how it has accelerated and decelerated since, then he can accurately know the current orientation, position, and velocity of the car at any time.

    All inertial navigation systems suffer from integration drift: small errors in the measurement of acceleration and angular velocity are integrated into progressively larger errors in velocity, which are compounded into still greater errors in position. Since the new position is calculated from the previous calculated position and the measured acceleration and angular velocity, these errors accumulate roughly proportionally to the time since the initial position was input. Even the best accelerometers, with a standard error of 10 micro-g, would accumulate a 50-meter error within 17 minutes. Therefore, the position must be periodically corrected by input from some other type of navigation system.

    Accordingly, inertial navigation is usually used to supplement other navigation systems, providing a higher degree of accuracy than is possible with the use of any single system. For example, if, in terrestrial use, the inertially tracked velocity is intermittently updated to zero by stopping, the position will remain precise for a much longer time, a so-called zero velocity update. In aerospace particularly, other measurement systems are used to determine INS inaccuracies, e.g. the Honeywell LaseRefV inertial navigation systems uses GPS and air data computer outputs to maintain required navigation performance. The navigation error rises with the lower sensitivity of the sensors used. Currently, devices combining different sensors are being developed, e.g. attitude and heading reference system. Because the navigation error is mainly influenced by the numerical integration of angular rates and accelerations, the Pressure Reference System was developed to use one numerical integration of the angular rate measurements.

    Estimation theory in general and Kalman filtering in particular, provide a theoretical framework for combining information from various sensors. One of the most common alternative sensors is a satellite navigation radio such as GPS, which can be used for all kinds of vehicles with direct sky visibility. Indoor applications can use pedometers, distance measurement equipment, or other kinds of position sensors. By properly combining the information from an INS and other systems (GPS/INS), the errors in position and velocity are stable. Furthermore, INS can be used as a short-term fallback while GPS signals are unavailable, for example when a vehicle passes through a tunnel.

    In 2011, GPS jamming at the civilian level became a governmental concern. The relative ease in ability to jam these systems has motivated the military to reduce navigation dependence on GPS technology. Because inertial navigation sensors do not depend on radio signals unlike GPS, they cannot be jammed.

    In 2012, researchers at the U.S. Army Research Laboratory reported an inertial measurement unit consisting of micro-electromechanical system triaxial accelerometers and tri-axial gyroscopes with an array size of 10 that had a Kalman filter algorithm to estimate sensor nuisance parameters (errors) and munition position and velocity. Each array measures six data points and the system coordinates the data together to deliver a navigation solution. If one sensor consistently over or underestimates distance, the system can adjust, adjusting the corrupted sensor's contributions to the final calculation.

    The addition of the heuristic algorithm reduced a flight's calculated distance error from 120m to 40m from the designated target. The researchers coupled the algorithm with GPS or radar technology to initial and aid the navigation algorithm. At various points during the munition's flight they would cut off tracking and estimate the accuracy of the munition's landing. In a forty-second flight, 10s and 20s availability of aiding demonstrated little difference in error as both were approximately 35m off target. No noticeable difference was observed when experimentation took place with 100 sensor arrays rather than ten. The researchers indicate this limited experimental data signifies an optimization of navigation technology and a potential reduction in cost of military systems.

    RFT 507: Snitch Program For GA? Jun 10, 2021
    Show notes

    FOQA is a voluntary safety program that is designed to make commercial aviation safer by allowing commercial airlines and pilots to share de-identified aggregate information with the FAA so that the FAA can monitor national trends in aircraft operations and target its resources to address operational risk issues (e.g., flight operations, air traffic control (ATC), airports). The fundamental objective of this new FAA/pilot/carrier partnership is to allow all three parties to identify and reduce or eliminate safety risks, as well as minimize deviations from the regulations. To achieve this objective and obtain valuable safety information, the airlines, pilots, and the FAA are voluntarily agreeing to participate in this program so that all three organizations can achieve a mutual goal of making air travel safer.

    From AOPA:

    The FAA requires ADS-B Out capability in the continental United States, in the ADS-B rule airspace designated by FAR 91.225:

    • Class A, B, and C airspace;
    • Class E airspace at or above 10,000 feet msl, excluding airspace at and below 2,500 feet agl;
    • Within 30 nautical miles of a Class B primary airport (the Mode C veil);
    • Above the ceiling and within the lateral boundaries of Class B or Class C airspace up to 10,000 feet;
    • Class E airspace over the Gulf of Mexico, at and above 3,000 feet msl, within 12 nm of the U.S. coast.

    From AvWeb Insider:

    If I were more diligent about keeping logbooks, I could look up the date when my airplane partner and I flew up to meet John and Martha King in Jacksonville for some kind of event or another. When we got to the airport to depart, the weather was crap; probably ¼-mile and indefinite ceiling. It was night. This was—and probably still is—just the kind of instrument flying I love. I remember John saying he agreed and was happy to see someone else actually doing it.

    Despite that avuncular presence on the green screen, Mr. King’s inner wild child is revealed by another comment he made earlier that day when we were discussing the five bad attitudes the FAA is always trying to browbeat us with to warn that a mild-mannered podiatrist can metastasize into a psychopath at just a whiff of 100LL. You remember them, right? Anti-authority, impulsivity, invulnerability, macho and resignation. “Hell,” John observed, “you have to have three of those just to want to be a pilot in the first place.” My three are that I have resigned myself to my anti-authoritarian impulsivity and so far my machismo has rendered me untouchable. I guess I’m over budget.

    And here, I’ll segue into the Martha Lunken story Russ Niles filed this week and which is otherwise bouncing around social media like a rubber check in a tile bathroom. Summary: Ms. Lunken, a well-known Ohio aviation personality and Flying Magazine columnist, decided, on a whim, to fly under the Jeremiah Morrow Bridge that carries I-71 over the Little Miami River in Oregonia. Ohio. Here’s a picture, so you can see the appeal. It’s the highest bridge in Ohio. If your reaction is, “that would be a cakewalk,” you’re not alone.

    But the act is indefensibly boneheaded, which she admits. But for one line in the FAA enforcement letter, it’s not wild-eyed crazy, either. The line is: There were people under the bridge. It provides no further detail so we don’t know if they were in boats or having picnics on the shore. For me personally, if I were willing to take on the bridge stunt, I’m not willing to risk the remote chance of having the flaming wreckage with me in it land between the chicken and the potato salad of the Stooldrear’s Sunday outing. That, if you’ll pardon me, is a bridge too far.

    I’m not too worried about knocking the bridge over or hitting cars. Still, I wouldn’t try it for reasons related to the thrill-versus-consequences ratio. The potential ^%$ storm Ms. Lunken is now inevitably enduring, with this blog being another predictable gust, is hardly worth the payoff. Now if I were flying with Michael Goulian inverted … give me a minute on that. Nor would I accept the argument that one bridge buzz job is necessarily emblematic of a pattern of bad judgment or a gateway drug to yet more demented acts, say, like buying an Ercoupe.

    Being a columnist and all, Lunken is an opinion leader of sorts and thus expected to be, if not a moral guidepost, at least not too much of a knucklehead. It is a kind of burden to bear, earned or deserved or not. Readers develop a perception of a media persona as somehow an exemplar. Perhaps showing yourself to be all too human is the on-ramp to redemption. Nonetheless, one needn’t bore holes under a major interstate artery to reach that higher plane of aeronautical wisdom conferred upon those of us who sin, repent and rejoin the flock. The more mundane runway excursions, fuel exhaustions and taxiing into hangar doors should suffice without the prospect of a permanent chair on the beach because you appeared to show criminal intent.

    The eye-opener is that the FAA raised the charge to Murder 1 because they claimed Lunken intentionally turned off her ADS-B to avoid detection. She says she did not. This shows the low standard of proof in administrative law. You are presumed guilty if the government says you are and the burden is on you to prove otherwise. They revoked all of her certificates. She has to start anew if she wants to fly again. Odd calculus indeed. If I had to go through all that just to reinstate my certificates, I’d rejoin my bowling league. That said, there might yet be a pretty good T-shirt business is this. Aviation, like motorcycling, has its outlaw contingent.

    Her case also shows the uneven way penalties are assessed. The day before we reported this, I got a call from a reporter in Oregon asking about a case where a local pilot—the mayor of a town—was suspended for 200 days for operating a Skyhawk that was two years out of annual and without having had a flight review in six years. He appears to have run the airplane out of gas and landed on a beach causing grievous injuries to one of his passengers. Scroll to 11:11 in this video to see it. In my view, he got a light sentence despite a persistent pattern of bad judgment and noncompliance.

    While we’re at it, don’t let it escape notice that ADS-B is now an enforcement tool, even if isn’t working. And I did not know that if the FAA decides you turned it off to evade detection, it’s an automatic—or at least potential—revocation.

    And since bad things come in threes, I learned of another accident this week in which ADS-B may be a factor. A flight school Skyhawk crash landed on a golf course after an ADS-B track that may show impromptu aerobatics. Even if that isn’t true, the ADS-B will be the music for a rug dance for the pilots, I’m sure.

    There are two blades to this dull axe. On the one hand, if knowing that ADS-B is the all-seeing eye it may appear to be serves as an inhibition to doing stupid stuff—like flying under bridges on a whim—that’s not a bad thing. On the other hand, the data might be compromised or made to somehow catch you in a marginal act leading to enforcement that wouldn’t have otherwise happened. I’d much prefer they spend their resources trying to find causes for all those unknown engine failures.

    Of course, if your airplane has no electrical system, like my old Cub, that’s different, isn’t it? (It does have the 1930’s style three-foot N-numbers under the wing, however.) I’m still not doing the bridge thing. Bucket list or not, I’ve never liked explaining myself and I’m pretty sure I’m not gonna start now. Don’t want the time, not doing the crime.
