The 2014 Mojave FAI Records Jamboree The Idea of a Records Jamboree is Crystalized It started in January when I was asked to make a pres of the Felix Baumgartner Edge of Space parachute jump to the Scaled Composites engineering staff at Mojave. Also accompanying me was Paulo Iscold from Brazil. Paulo is a professor of and led the student team in the development of the CEA 308 aircr that set 5 world records in 2010. Paulo had been asked to present his experiences with the CEA 308 project which was modelled German Akaflieg format that has had such a c influence on sailplane technology. the The coordinator of the event for Scaled Composites was Scaled Composites Project Engineer Elliot Seguin. In addi on to his project engineer , Elliot is an avid racing pilot, having built two racing airplanes, one of which was his own design, and for the last six years has raced in the annual Reno Air Races and achieved a Gold finish. While I was there he told me that he was also involved in the planning for the annual Mojave Experimental Fly-In to be held in April. This is a very popular event with hundreds of ai flying in for the event. Among the ees were expected to be pilots with high performance aircr who might be interested in s ng world records. His idea was to add a “Records Event” to the fly-in. If several pilots were interested in a emp ng world records in a single coordinated event, the cost of suppor ng the event could be shared. It sounded like a good idea to me and NAA headquarters was brought into the Page | 1 The 2014 Mojave FAI Records Jamboree discussion. The NAA agreed to support the concept and the week leading up to the fly -in was set aside for record pts. In addi on, the NAA assigned Kris Maynard of the Contest and Records Board to assist in the Observer tasks dealing with the mul ple pilot/aircra environment. It should be noted that Mojave and Scaled Composites are no strangers to the avi on world record scene. Who can forget the 9 day, non-stop, around-the-world flight by Richard Rutan and Jeana Jaeger in the Rutan Voyager, or the non-stop around-the-world flights by Steve in the Rutan Global Flyer, or the closed course speed records set in the Rutan Catbird by Richard Rutan and Mike Melvill, or the Rutan SpaceshipOne – winner of the Ansari X Prize. The fly-in dates were set for April 19 – 20 with the 16 – 18 set aside for the record pts. Four pilots signed up for the a empts: Tom Aberle with his C-1a class Phantom biplane Reno racer Lee Behel with his C-1b class GP-5 racer Mike Patey with his C-1c class Lancair Legacy Zach Reeder with his C-1c class Rutan Catbird As it turned out, Lee Behel had a schedule conflict which meant he would be out of the country during the planned records event. He could make April 11 – 12 so we agreed to make this the first phase of the jamboree. Unfortunately, Kris would only be available for the later schedule. Records Selected for Challenge As can be seen from the chart below, with one exce n, all of the records were at least years old. One of the reasons there had been so li le with these records was the cost of observing and v record performances to be paid by the challenger. This cost has changed through the intr of precision GPS data logging devices that could accurately measure high speed flights without an observer on board or a large team on the Page | 2 The 2014 Mojave FAI Records Jamboree ground. This was the motivation for the NAA to invest in the Novatel DL-4 GPS equipment. Since the acquisition of the DL-4 in 2004, this instrument has been the instrument of choice in verifying twenty two world records. The Aberle Phantom and the Behel GP-5 both would require the DL-4 for record performance validation. As part of the normal preparation process I forwarded to them the requirements for installing the DL-4 recorder and dual frequency antenna. Establishing the Courses The Google Earth imaging of the earth surface is an excellent tool for evaluating potential courses. No longer are surveyors required to precisely position start and finish lines or control points. With Google Earth it is possible to remotely study an area, identify ground reference points and determine the coordinates and elevation for all points of interest. The final step is to use the FAI Calculator in order to obtain the precise distance between specified points of interest. The GPS recording of the flight is then mapped against the points specified. The most challenging course in terms of precision is the 3km speed course because small errors are magnified due to the shortness of the course and speed of the aircraft. As I expected, the 3km course proved to be the one requiring the most work before it met all requirements. 3km Course In almost every previous record, an airport runway has been used as the underlying navigational target for the course. Accordingly, I laid out a course with approaches and start/finish lines for review by the organizer and record seeking pilots. Four passes of the course are required, two in each direction. Each end is marked by an approach line. The inner lines are the start/finish lines for the actual speed measurement. When flying the course the approach lines are the most critical because the height of the aircraft over the approach line establishes the critical height boundaries for the remainder of the pass. The aircraft cannot descend more than 100 meters after crossing the approach line without voiding the flight. The pilot will focus on both altitude and maximum speed through the entire pass. The post flight data analysis will monitor flight altitudes and determine the speed by the elapsed time between the start and finish lines. When the course detail was reviewed by the airport Page | 3 The 2014 Mojave FAI Records Jamboree management it was rejected for op onal reasons including pote traffic conflicts. Two altern ves were evaluated, again using Google Earth: 1. A straight s on of railway line to the north of the airport 2. A dirt road to the east of the airport (Mojave 20th Street) Lee Behel agreed to fly over both courses and evaluate them for pilot preference. His report showed a preference for the eastern course due to the open approaches while the railroad had telephone lines and bridges that were pote hazards in low level flight. The eastern course would need to have clear approach markings established by using vehicles in the road at the approach point. Given Lee’s report the decision was made to use the eastern course as recommended. A more detailed view of the course was prepared showing the approaches, start and finish points and the surounding terrain. The south end of the course was clearly marked by highway CA58 just south of the approach line and running east/west. The north end clearly needed to have visible markers in place so it was assumed that vehicles would be placed at the approximate approach line. A review by airport management received their approval so this course was selected as the official course for the record events. 15km Course California highway 14 running from Mojave to Inyokern was an excellent candidate for the 15km course. I found a straight that ran NNE from the inte with Ca58 just north of Mojave and was just over 15km in length. I was able to construct reasonable approaches of 5km at each end with good visual references. The course is highlighted in blue and the approaches at each end are highlighted in green. The 15km rules do not specify course which provides a lot of flexibility in the course layout. The Mojave airport can be seen in the lower corner of the image. Page | 4 The 2014 Mojave FAI Records Jamboree 5,000km Course The long distance (> 25 km) closed speed courses require an out and return layout with the choice of one or two control points. Mul ple laps are allowed, thus providing a wide range of course Courses that require from two to ten laps were evaluated taking into consider terrain, winds, flight des, weather and turn point navi on. The analysis gave the shorter course more points due to the smaller footprint of the flight and more predictable weather. This was especially true considering that the flight would probably last up to sixteen hours. Zach Reeder elected for a course following the White Mountains with an intermediated turn point at Inyokern, about 70km from Mojave. This would result in a lap just over 500km long and would, therefore, require 10 laps to complete the 5,000km course The course is shown on the le : Mojave is at the southern end of the course and Inyokern aiport is at the intermediate control point. Zach mated an average speed of 200 knots which would result in a flight me of about 14 hours. Page | 5 The 2014 Mojave FAI Records Jamboree 1,000km, 2,000km Courses Mike Patey elected for a 1,000km lap which would allow him to cover both the 1,000km and 2,000km records with one flight. The 1000km attempt would be the first of the two laps required for the 2000km attempt. The course he selected was an east / west course starting at Palmdale, just south of Mojave and south of the Edwards restricted flight area with a control point just north of Prescott, Arizona. By flying just below class A airspace, Mike would not have to deal with IFR flight rules but would be able to take advantage of a lower air density. 3,000m Time To Climb This is, perhaps, the simplest course to define. Only two points are required: The elevation and time of the start of the take-off roll The time at which the aircraft passes through the height of 3,000m above the starting point elevation Sounds simple – yes? Just calculate the elapsed time between these two events and correct to UTC. Actually it can be quite tricky. Determining the start of the take-off roll is usually by one of three techniques: Visual observation of the start of roll with time correlated to UTC time. This requires the observer to be as close as possible to the aircraft as it starts the take-off role. Airport restrictions may cause difficulties here due to the inability to be close enough to accurately detect the beginning of motion. Using a precision GPS data logger with sufficient accuracy to capture the initial movement of the aircraft. With an observer on board who logs both the start of roll and passing through the target altitude. A video camera in the aircraft can be used to simultaneously record altitude and time from the instrument panel. Page | 6 The 2014 Mojave FAI Records Jamboree Since the aircraft involved were single seaters, both of the first two methods were employed. For the visual observation, this observer used a timepiece that was synchronized to UTC time. Final Preparations I arrived on the evening of May 10 and arranged to meet with Elliot the next morning. Lee Behel was schedule to arrive about mid-afternoon to prep his aircraft for the record attempts on Saturday the 12th. The first priority was to inspect the 3km course and insure that it would satisfy the requirements for navigation and record observation and validation. The course is laid out on the Mojave 20th Street and is only a dirt road. The view on the left is looking north from the south approach. Just below the aircraft at this point is the intersection of Business highway 58 and highway 58 bypass providing a very visible landmark. To the left and out of sight is the Mojave airport. The yellow markers in the foreground define the approach line; the yellow marker along the course is the start point. The red line in the distance is the finish line. From the north the approach shown here is much more difficult to identify so the decision was made to place at least two vehicles at the approach point. Beyond the approach line is the marker for the start point. Of these two points the approach line is much more important from a pilot’s perspective because crossing the approach line determines the flight altitude limits through to the finish line. We drove the trail to the northern approach to determine its precise position. As can be seen in this photo, apart from a small cleared area there is nothing of any distinction that would be recognizable from the Page | 7 The 2014 Mojave FAI Records Jamboree air. The task at hand was to mark the spot so the crew with trucks would know where to park them for the record runs. Elliot and I scrounged up a few scraps of wood and planted them in a somewhat conspicuous spot assuming that they would be undisturbed pending the arrival of the north approach crew. On the way to the north end we had no ced what appeared to be a sheepherder’s camp down a side street. We decided to see if anyone occupied the camp. As we approached we could see no sign of life but it did appear to be in use. Watering troughs were around the camp – a sure sign that stock animals may be in the area. We retraced our steps and looked for signs of animals. In the distance on another side street we could see a truck so we ed. There we found an 81 year old sheepherder named Miguel. He told us he had a herd of 1,000 sheep and grazed his herd in this every year. We told him we would be flying very low over the area the next day and didn’t want to cause a problem for his herd. He understood and said he would move his sheep away from the 20th street track. He told us that he had come to this country from Spain when he was 19 years old, and had pursued his living just as he had in the old country ever since. It was a most pleasant mee ng. Before we knew it the herd decided to inve and soon we were surrounded by all 1,000 sheep. This was the last that we would see of the sheep and Miguel. Having completed our survey we returned to the airport and met with the airport and tower management to review our plans and coordinate op ons. One of our requests was permission to park my car as a ground n near the runway. The DL-4 ground sta on was in my car and Page | 8 The 2014 Mojave FAI Records Jamboree needed to be parked in a location with a clear 360 degree view of the horizon. The staff was very helpful and we completed the meeting optimistic about our ability to manage the record attempts. Lee Behel Records Lee arrived mid-afternoon in his beautiful GP-5 Reno Racer and parked it in a reserved hangar for pre-flight preparations. These included: Installation of the DL-4 and battery Hooking up to the aircraft static system Installing the DL-4 antenna Establishing the gross flight weight It goes without saying that a racing machine does not have a surplus of space for extra equipment, but Lee’s crew was up to the task of finding room for the DL-4 equipment. Because Observer access is necessary for turning the unit on and confirming operating status is necessary before flight, several installation configurations were tried before one was found that did the job. The answer for the DL-4 was to mount it under the front edge of the pilot seat. The antenna was another challenge. It required cutting a hole in the top of the fuselage behind the cockpit in order to provide 360 degree coverage of the horizon in flight. After installation of the DL-4 the aircraft was wheeled outside the hanger and a 10 minute test run of the GPS system was completed in order to verify its operational status. Everything checked out OK. Before weighing, Lee wanted to remove about 5 gallons of fuel in order to reduce the aircraft weight. His plan was to fly the 3k Time To Climb task first and then fly the speed tasks. The weighing process was uneventful. The scales had been recently calibrated and the zeroing step was very straightforward. Each scale was zeroed in turn, and then the scales were summed and checked. The scales measured between 1,925 and 1,927 lbs., well within the class C-1b range of 1,102 – 2,205 lbs. Page | 9 The 2014 Mojave FAI Records Jamboree By now it was time to go to a scheduled briefing for all hands. The local Mexican restaurant was the venue for the briefing, which facilitated a relaxing while serious atmosphere. The Briefing Elliot conducted the briefing, and it was attended by the ground crews, aircraft crews and NAA, about 30 in all. Much of the discussion revolved around the 3km course and the rules for personnel placement. The crew for establishing the North approach point was instructed to depart at least 30 minutes before expected take-off due to the condition of the unpaved road. All those expected to be in the proximity of the 3km course were advised of the FAA rules requiring at least 500’ separation from the expected flight path of the aircraft. The sequencing of the various events was also covered as well as rules for moving about the airport. All hands were asked to be at the airport by 6:00 am to be prepared for an early launch in order to take advantage of early morning calm. It was a beautiful evening, and spirits were high for the next day. April 12, 6:00 am Driving to the airport, it was clear that there would not be an early start. The wind was howling and trees were bent over in protest. Low level turbulence was a certainty which would make the 3km run particularly difficult. The teams met at the hangar and we were advised that the winds were gusting to 45 knots! It must have been a local phenomenon because none of the other airports in the valley were reporting strong winds. Mojave is situated at the mouth of the canyon that leads to Tehachapi and Bakersfield – and that is where the west wind was coming from. Local knowledge advised that there was a good chance the winds would die down during the day. The question was when because both Lee and I had early departures scheduled. As 9:00 approached, the winds subsided a little – gusts to 35 knots. Lee decided that it was just below his threshold and so he was ready to go. I had briefed Lee on the rules for both the 3km and 15km speed runs and what to look out for. The 3km course sloped 65’ downhill from the north to the south. Since the record restricted the vertical flight band to 330’ from approach to finish it would be easy to misjudge when flying very low levels. Lee elected to start from the north end of the course and then, if all went well, go immediately to the 15km course and make an attempt before landing. For the time to climb I told Lee that I wanted him to get into take-off position and then hold for 60 seconds in order to give the GPS unit time to mark that position then take-off. At the same time I would get a visual confirmation of his take-off time. Lee decided to try the time to climb first. As we had planned, I was escorted to the location for the ground station between runway 26 and the control tower. The DL-4 was started and satellite acquisition confirmed. Lee went back to the hangar to start the aircraft DL-4 to depart for the runway. He planned to take Page | 10 The 2014 Mojave FAI Records Jamboree his time in order to thoroughly warm up his engine and engine oil. Lee paused for the one minute as requested and then with the wind blowing 35 knots started his take‐off roll. It was very short and after a brief level acceleration pause he headed for the stars. From the ground his climb appeared to be almost vertical and he was quickly out of sight. Within three or four minutes we heard him returning and entering the landing pattern. His entire flight lasted exactly 8 minutes! Back at the hangar I retrieved the DL‐4 data cards to determine if we had good data. The data looked OK but getting the performance numbers is a fairly complex process because the exact altitude reached is based upon corrected pressure data. The pressure sensors used with the DL‐4’s are extremely accurate but still require matching with local sounding data to be sure that variations in the local environment are taken into account for the final result. The nearest weather station with sounding data is Las Vegas – close enough for our purposes. Sounding balloons are launched twice a day at 00:00Z and 12:00Z. Because the flight takes place between the soundings I had only the 12:00Z data for my initial analysis. This would provide an approximate result but required the next sounding in order to properly interpolate between them. My initial reading showed a time of about 120 seconds vs. the current record of 140 seconds – enough to know that the official record was about to change! The final analysis also revealed a small error in entering runway elevation that slightly affected the result. The final results are summarized here. Given the length of time the old record has been in the books – 15 years it may be a long time again before a successful challenger appears. Now for the speed runs. The GP‐5 was refueled with the fuel that had been removed from the aircraft yesterday. Because the weight of the added fuel was less than the class weight margin, without taking into consideration the fuel used, the additional weighing was waved. The DL‐4 data cards were prepped for the next flight and installed in the aircraft and ground station. We repeated the base station placement and started the recording process and then started the aircraft DL‐4. Lee told us that he would loiter for a few minutes after take‐off to insure the engine was ready for the maximum thrust speed runs. This gave Elliot and me sufficient time to go to the south end of the course to observe each of the four passes over the course, two in each direction. Shortly after we arrived we received a radio call that he was beginning his first pass. We could hear him coming but could not see him finally one of the crew noticed that Lee was flying south one street further to the east Page | 11 The 2014 Mojave FAI Records Jamboree from the course. He had picked the wrong road to follow from the north – apparently having missed our ground station. We radioed him right away, and he restarted the first pass again from the north. This time we had a very good visual on him. It was obvious from the way the plane was bouncing that it was very rough. On landing Lee remarked that it was the roughest flight he had ever experienced. The Gmeter registered + 5 g’s and he mentioned that he was concerned about the possibility of structural damage to the aircraft. He was not deterred however, proceeding directly to the 15km course as soon as he finished the four required 3km passes. The two 15k passes were uneventful and he landed just over 44 minutes later. For those of us on the ground, the sight and sound of the GP-5 screaming down the course on the deck was a thrill not to be forgotten. Unfortunately, only a handful of us could share this experience. After a record flight there is always tenseness in the area while the data is being analyzed. This was certainly the case after these torturous runs, and the results looked good. For the 3km record 605.12km/h (356.4mph) is 5.5% faster than the old record of 573.5km/h and for the 15km record 609.35km/h (378.6mph) is a whopping 25.1% faster than the old record of 487.1km/h! Three world records were set in two hours and seventeen minutes, not a bad start to the Mojave Record Jamboree. Phase Two: April 16 – 18, 2014 I arrived at Mojave early in the evening and after checking into the Mariah Hotel, went into the dining room for a quick bite. In the corner of the room I saw a large table and recognized Tom Aberle and his crew. I was immediately invited to join them for dinner, which I gratefully accepted. Tom is a very experienced Reno racing pilot having set seven speed records winning the Biplane Gold Championship at least eight times. He is hoping to translate the Phantom’s Reno winning record into FAI World Records. He is also a very genial man with a dedicated crew headed by his son Jerry. Because of the DL-4 installation we agreed to start preparations at 6:00 am the next morning. Page | 12 The 2014 Mojave FAI Records Jamboree April 17 The plan for today is to get all aircraft flight ready in order to accomplish all flights tomorrow. The planned activities are: Aberly Phantom o Install DL-4 o Install static system (the aircraft does not have a static system built-in) o Weigh aircraft Patey Lancair Legacy o Mike Patey is not expected to arrive until mid afternoon o Set up the Nano flight recorder (see notes on this recorder below) o Weigh aircraft o Resolve course coordinates Reeder Catbird o Review fuel tanks installation o Set up the Nano flight recorder o Weigh aircraft Nano Flight Recorder This flight recorder by lxnav is approved by the International Gliding Commission for certifying gliding records and has some attractive attributes that also make it useful for General Aviation records when the one second sampling rate is adequate for the speeds and distances being measured. It has the following general characteristics: Small physical size: 2.6” x 1.6” x 0.8” Weighs 2.1 oz Antenna is integrated into the body Pressure sensor measuring up to 16,000 meters (52,500’) Internal lithium-ion battery good for up to 28 hours of operation 2 GB of removable storage (micro SD card) Built in security system to eliminate tampering with the data USB interface and Bluetooth communications These stand-alone characteristics are perfect for simple installation and the long flights of Reeder and Patey. All that is required is a perch that insures adequate exposure to the sky. Page | 13 The 2014 Mojave FAI Records Jamboree Phantom This is a remarkable biplane with an unblemished Reno racing record. The photo here was taken at the 2011 Reno Races. Tom is left on the back row. Due to the limited space the DL-4 was mounted on a vertical strut behind the pilot seat. The antenna was mounted on a special recess created on the engine cowling. To solve the static problem, Elliot offered a miniature static probe that was mounted into the rear fuselage upper surface and connected internally to the DL-4 pressure sensor. By early afternoon the crew was ready for the weighing, and Kris Maynard had arrived to assist in the preparations. The scales were zeroed and the Phantom rolled onto the scales. The Class C-1a upper limit is 1,102 lbs. There was shock on the faces of the crew. This result was not expected. Now the question was what to do? Tom suggested that the wheel pants would be a good place to start. It turns out that the wheel pants also contained a small tank behind the wheel which could be used for ballast. Tom asked the crew “did we ever empty these tanks? Let’s see if there is any fuel in there.” Sure enough both tanks contained fuel that had been used as ballast and never emptied. The fuel was drained out and the weighing repeated. Now there was six pounds of margin and the Phantom was good to go. Lancair Legacy About mid-afternoon Mike Patey arrived with his newly modified and painted Legacy. It is a beautiful ship with all the latest technology on board, new winglets, extended landing gear and dual turbo charged and supercharged Lycoming 780. The Legacy was quickly wheeled into the hangar alongside the Phantom, and rolled onto the Page | 14 The 2014 Mojave FAI Records Jamboree scales. Being a class C‐1c aircraft the maximum allowed gross weight is 3,858 lbs. (1,750kg). With Mike on board the scales showed 2,687 lbs. well below the maximum. However Mike needed to add fuel before the flight the next day. We agreed to add the fuel weight to the measured weight. After fueling with 52 gallons of low lead 100 the total weight was 3008.4 lbs. (1,364.6kg), well below the maximum permitted. Catbird Originally designed by Burt Rutan as a possible replacement for the Beechcraft Bonanza in 1988, the aircraft is an all composite four passenger high speed aircraft that currently holds two world records including the 2,000km closed course speed record that Mike Patey will attempt to break tomorrow. Zach Reeder has restored the aircraft and installed additional fuel cells in the rear passenger compartment for the 5,000 km record attempt tomorrow. Since there is no existing record Zach need only finish in order to claim the record. It is late afternoon and the weighing is the last scheduled event before the scheduled briefing. Kris inspected the fuel tanks and sealed the fuel caps as we completed the scales calibration then we rolled the Catbird onto the scales. Zach donned his flying suit and parachute and climbed aboard. The scales registered 2,891 lbs. well within the allowed 3,858 lbs. The Catbird was Good to Go! The briefing by Elliot was a repeat of last week’s briefing with specific focus on the 3km course and marking the north approach point. All hands were expected to be at the airport by 6:00am. Before retiring I set up the Nano flight recorders with pilot names and noted the last recorded data files. April 18, Flight Day By the time Kris and I arrived the Catbird was out of the hangar and Zach was in final stages of getting ready to depart. The Phantom was being wheeled out and soon Mike showed up to prep the Legacy. Page | 15 The 2014 Mojave FAI Records Jamboree Events were now occurring at high speed: I installed the Nano flight recorders in the Catbird and Legacy and started them at 6:10 am Zach started his taxi to the runway at 6:15 am The ground crew with Kris was dispatched to the 3km north approach at 6:30 am I installed the DL-4 data cards at 6:35 am and started the ground station at 6:40 am At 7:00 am Mike Patey taxied to the runway taking off at 7:04 am I started the Phantom DL-4 at 7:04 am and headed for the 3km course south approach with Elliot Tom Aberle in the Phantom takes off at 7:08 am for the 3km course Aberly Tom had decided to land and re-fuel before trying the 15km course. This gave me an opportunity to take a quick look at the 3km results. Unfortunately, Tom’s speed was 15 km/h slower than the current record of 468.8 km/h. Needless to say, Tom and his crew were very disappointed. Tom decided not to try for the 15km record since he felt he would not be able to improve enough to beat the 15k record of 454.8 km/h. He would have to beat it by 3% or 468.44 km/h. Instead he decided to attempt to beat the 3k Time to Climb record of Bohannon at 3:08 minutes. The result unfortunately was not enough to even match the old record. Tom and his crew, in spite of being terribly disappointed, accepted the results as a challenge to do whatever it takes to improve the Phantom enough to achieve the same supremacy in the FAI record arena as they had in the Reno Pylon arena. The lesson learned is that doing well in one does not forecast how one will do in the other. Patey Meanwhile, Mike was completing his 1000km and 2000km Closed Course speed runs. Sure enough at 11:15 am the unmistakable growl of the Legacy’s Lycoming 780 could be heard. Mike was obviously pleased with his flight as he made a crowd pleasing victory pass before touching down. A quick look at the Nano data indicated a potential problem with one of the turn points. On closer inspection the problem turned out to be one digit in the turnpoint coordinates that had been entered incorrectly. We breathed a sigh of relief and went on to score the flight starting with the 2,000km data. Page | 16 The 2014 Mojave FAI Records Jamboree The final result showed a dramatic improvement of 24.3% over the current record; 319.63 mph vs. 257.12 mph (514.4 km/h vs. 413.8 km/h). The modifications to the Legacy have really paid off. There was a close call, however. The start altitude was 4,423 meters and the finish altitude was 4,427 meters – only 4 meters above the required minimum for the record! Since the 1,000km result is the first pass of the course, establishing the speed should be very simple – yes? Not so simple! The rules say that the finish line must be crossed, but in rounding the finish point the path of the aircraft never actually crossed the finish line. The aircraft actually went around the finish line. So how do we determine what the finish time is, if at all? The General Section of the FAI rules anticipates this issue and provide for 45 degree extensions of the ends of the finish line. The task was therefore to determine when the aircraft crossed the first 45 degree extension to establish the finish time and therefore the course speed. The final speed is 319.85 mph (514.76 km/h), 6.2% faster than the speed set by John Harris in 1975 flying a prototype Bellanca Skyrocket II. So, Mike finishes with two records, having decided not to attempt the 500km at this time, saving the challenge for another occasion. Reeder Meanwhile, the Catbird passes over the Mojave airport like clockwork about every 90 minutes flying above 20,000’ but still visible to the naked eye. Late afternoon saw cumulonimbus clouds developing over the Sierras and appeared to be moving toward the flight path potentially threatening the flight. Fortunately, Zach was able to dodge the bullet and continue his quest. As day turned to night the waiting crowd dwindled until by 9:00 pm only a few hardy friends were on the watch. By this time Zach was on his last lap and a big cheer went up as his navigation lights appeared overhead heading toward the finish line. Zach had been airborne for more than 15 hours. He crossed the finish line and began a long, slow descent to landing 16 minutes later. As the analysis would later show, every control point had been successfully navigated and Zach had set a speed record of 207.82 mph (334.44km/h). Page | 17 The 2014 Mojave FAI Records Jamboree There was no time to evaluate the flight that evening, but everyone including Zach knew he had succeeded in establishing a first time ever record - so the celebration started. In spite of the long day and late hour, Zach did not show any sign of fatigue – perhaps the adrenalin surge and emotion of having completed the task was enough to overcome it. April 19, the Mojave Fly-In Kris and I finished the preliminary analysis of all the flights, and then went to the airport to enjoy all of the beautiful aircraft on the ramp. It was a great time to relax and meet and greet old friends. Among them was John Parker who was there with his Thunder Mustang – holder of three world records. John’s records were the first records set using the DL-4 GPS units for performance measurement and validation. The day concluded with a banquet attended by many (I don’t have the count) of the fly-in pilots. Mike Patey and Zach Reeder received Experimenter Awards, and the preliminary results of the world record attempts were announced.
