Participated in my first NASA GA research project (long)
A few months ago I saw a news item on WSI's website (an aviation weather
provider for pre-flight and in-flight) stating that NASA was looking for pilots of all experience levels to participate in upcoming GA research projects. For the fun of it, I completed the web-based survey, which asked about my certificate, medical, ratings, aircraft time, and flight time. Two weeks ago I received both an email and a phone call stating that my aviation experiences qualified me for their latest GA research project, a comparable safety study between round gauges and different primary flight displays, what they call "Synthetic Vision Displays." I called the coordinator right back and was offered a slot, which I eagerly accepted. NASA needed twenty five pilots, of which I was number twenty one. The study required me to travel to Newport News, Virginia last Thursday night, then spend the entire day Friday at the research center flying a simulator under various weather scenarios with different instruments/displays. NASA would pay for all travel expenses and provide a modest stipend for my participation. I didn't care about the money; I was motivated by this, my first opportunity to fly a full- motion, million dollar simulator and participate in a small part of GA's future. Friday morning started with a briefing of the overall research project, which was to determine whether there was an increased level of flight safety in aircraft equipped with primary flight displays. NASA would be testing three types of primary flight display and comparing my flights with the PFDs to my flights with "baseline" round gauges, then adding my results to the group of subject pilots to arrive at the group results. All three displays are variants of the Garmin G1000/Avidine PFD systems currently available with some notable enhancements, including one with simulated terrain and obstacles displayed on the primary display (synthetic vision display), as seen on page 24 of this PDF: http://avsp.larc.nasa.gov/pdfs/GVSIT...S_Overview.pdf After the research briefing, I spent the next two hours working with a CFII to become acquainted with the simulator, a 757 cockpit reprogrammed to the flight dynamics of a Cessna 206. The researchers covered the entire co-pilot's panel with wood to downplay the complexities of a 757 cockpit and placed a small LCD screen over the pilot's panel. On this screen they would display the baseline round gauges and the various PFDs, depending on the flight scenario. At first I was concerned that this 757 cockpit would be too much of a distraction, but incredibly it only took a couple of practice flights to get the feeling I was flying a Cessna 206. The airline yoke felt amazingly like the responsiveness of a Cessna yoke, thanks to some excellent reprogramming of the simulator. Reno International Airport, of Reno, Nevada was the airport of choice throughout the training and experiment. Reno was chosen for the obstacles under the traffic pattern (apparently two hotel/casino buildings were erected right under the base leg to 16L) and the nearby mountainous terrain. During the practice flights, the CFII had me perform some basic air and VFR pattern work, then called for the day-time low weather scenario for me to fly an ILS. On the first practice approach, I followed the ILS within acceptable tolerances and at the decision height I looked up but could not see the runway. Thus I declared a missed and began a straight-out climb out when the researcher stopped the scenario. The researcher told me that in that scenario the aircraft should have broken out at minimums and that I should have seen the runway to complete a landing. I again informed him that I didn't see it. Because this was only a practice flight, he and the CFII agreed that they would run the ILS approach again, but this time I was to look much harder for the runway. Again, I followed the ILS down to within tolerances and when I looked up, no runway. However, recalling what the researcher said, I spent an extra few seconds out the window (all without dropping below the DH) and the runway, like a ghost, came into sight. Now having a visual, I completed the landing and the scenario stopped. So, that was the problem, I told the researcher. The approach lights in this simulator are terrible. Normally, I would expect to see the approach lights at DH. Not seeing any approach lights, I assumed the visibility and clouds were much lower than expected and declared a missed, perhaps prematurely but certainly within my rights to do so. The researcher apologized for the rather poor approach lights simulation but informed me that there was nothing he could do to improve this. Unbeknownst to me, this would become a very interesting point later on. With the round gauges complete, I then flew three practice ILS's using the PFDs, starting with a PFD containing a simple flight director and moving to the more complex simulated vision display with terrain/obstacles and the "fly through flight path boxes" on the PFD. Two of the three approaches I again could not see the runway and declared a missed at DH, and two more times I received a "you should have seen the runway at DH. We were really expecting you to land" comment from the researcher. Expecting me to land? Who's flying the aircraft here, I thought. I was starting to get angry with this "expecting you to land" attitude and thought to point out that landing was not *his* option, especially with the poor approach light simulation going on. Instead, I stated that I would fly a missed if I couldn't see the runway. Soon it was noon and the practice sessions were complete. I was now pretty comfortable with the simulator so we broke for lunch. After lunch, I bid farewell to the CFII, whose job was now done, and I prepared to climb into the cockpit for the actual research scenarios. The eleven or so scenarios (a few visual approaches with both the gauges and the three PFDs, and a few ILS approaches with the gauges and PFDs) were scrambled up so that I wouldn't know what to expect as each one was run. At the end of each scenario, the researcher would ask me some questions about other traffic calls I overheard on the simulated ATC radio (presumably to gauge my workload). He then would hand me a tablet PC to answer 15 questions about my impressions of workload, comfort level, etc. during the flight scenario. Most of the afternoon simulated instrument approaches ended in a missed, too. However, the researcher did admit that those were designed to have weather much lower than DH. Eleven flights later, the test was over. I joined the researcher in his office for post research debriefing. He asked me about my overall impression of the new systems. I stated that flying behind the synthetic vision display PFD during instrument approaches was *very* nice. I did note that for VFR flying, less was better and there should be a "declutter" option to remove the terrain and obstacle information from the display on the most complex PFD. The researcher admitted that this was a recurring comment from the other pilots. He then asked me if I had any questions. Of the twenty subject pilots before me, did any of them crash, I asked. Two pilots hit the hotels on the base leg in low visibility and one hit the mountains, he responded. Interestingly, all were VFR-only pilots and all were flying the standard round gauges *or* the flight director PFD when they did so. Under the same weather conditions, all landed safely when using the more advanced PFDs with the synthetic displays. That was an interesting fact, I agreed. The researcher then asked me about the 757 simulator itself. Was it a distraction or was I comfortable in it. I commented that it helped having the copilot panel covered, but the flaps lever, which was a standard locking Boeing flaps lever and detents at every setting, was a bit distracting. I then reminded him of my unhappiness with the approach light simulation. My contribution to this study was now over. As he was showing me the door, the researcher suddenly stopped and looked at me, then said, "Now that we are done, I have a confession to make." OH? "The approach lights were purposely dimmed throughout this experiment because we wanted to see if you, the instrument rated pilot, would dip below minimums with this new technology. The FAA is very interested to see if pilots would be tempted to do something unsafe when behind these PFDs. "Of the previous twenty pilots participating so far, only one other pilot complained about the lack of approach lights and that pilot also executed a missed at or above DH every flight where marginal visibility was right at the DH." "Oh, one other question," the researcher stated. "Would you be interested in coming back around March '05 to participate in the second phase of this experiment, to be conducted while piloting NASA's Cessna 206 equipped with these PFDs?" "You bet I would!" I answered. No wonder they use psychologists to run these tests, I thought while walking out to my rental car with a big smile. Little did I know that the smile was short-lived for I spent the rest of the evening sitting in Philadelphia International, my USAirways connecting city, awaiting weather and a long line of airliners all competing for the one departing runway. A fitting end to an interesting day, it was. -- Peter |

The airline yoke felt amazingly like the responsiveness of a Cessna yoke, thanks to some excellent reprogramming of the simulator. I thought the same thing, too. I spent the first few minutes in the sim trying to figure out if I could squeeze it into my garage or if I'd have to build out a room in the basement... During the practice flights, the CFII had me perform some basic air and VFR pattern work, You should have seen my face when he asked me to turn *into* the mountain. "Um, that hill's pretty close. You sure we can make the turn?" "Yes, I want you familiar with what the terrain looks like in the sim and if you don't turn soon you *won't* make it." The researcher told me that in that scenario the aircraft should have broken out at minimums and that I should have seen the runway to complete a landing. I again informed him that I didn't see it. Because this was only a practice flight, he and the CFII agreed that they would run the ILS approach again, but this time I was to look much harder for the runway. hmph. Right. At the end of each scenario, the researcher would ask me some questions about other traffic calls I overheard on the simulated ATC radio (presumably to gauge my workload). He then would hand me a tablet PC to answer 15 questions about my impressions of workload, comfort level, etc. during the flight scenario. That's probably the best use of a TabletPC I've seen, yet. However, I felt a bit...odd voicing my answers, in addition. Most of the afternoon simulated instrument approaches ended in a missed, too. However, the researcher did admit that those were designed to have weather much lower than DH. He never told *me* that. He only told me afterwards that I should have been able to see the runway. Only once in the IMC runs was that the case and when I did I was already in the midst of initiating a go-around. Real-world, I'd've asked for another shot. I stated that flying behind the synthetic vision display PFD during instrument approaches was *very* nice. No kidding, it was - especially after flying two hours almost solid IMC to get there. The remains of what used to be Hurricane Ivan were moving up the Applachians and a solid wall of Level 3-5 thunderstorms prevented me from flying home that night. Flying home the next day was even *more* IMC than the trip down. Boy was I wishing for that SVS PFD! I did note that for VFR flying, less was better and there should be a "declutter" option to remove the terrain and obstacle information from the display on the most complex PFD. Yeah, that was my thought, too. He was a bit surprised by my rather quick "Oh, yes I do!" when he asked if I had any thoughts on the SVS PFD in VFR scenario. I had to keep reminding myself to look outside and stop trying to fly the technically perfect approach. Real-world, that could be a b-a-d situation. He then asked me if I had any questions. Of the twenty subject pilots before me, did any of them crash, I asked. I never crashed, but I absolutely blew the hell out of the ILS-in-IMC approach using round dials. I was tempted to request another shot, but was able to (barely!) recover the approach. At one point, I'd've sworn I saw a lightning flash. The strange thing was, I had to keep adding more and more power (much more than previous runs) to maintain airspeed/altitude. Later I found out that the "lightning" was actually the Aztec overtaking me in the "pattern" due to my slow speed. Nobody had an idea on the power situation and that was the only time it occurred. He did mention the simulator sometimes has a "contol lock"-type situation where it won't respond properly to control inputs. Two pilots hit the hotels on the base leg It was very cool watching the "obstruction block" in the SVS PFD swing by off my left wing when I couldn't see squat outside the window. My contribution to this study was now over. As he was showing me the door, the researcher suddenly stopped and looked at me, then said, "Now that we are done, I have a confession to make." OH? "The approach lights were purposely dimmed throughout this experiment because we wanted to see if you, the instrument rated pilot, would dip below minimums with this new technology.

"Of the previous twenty pilots participating so far, only one other pilot complained about the lack of approach lights and that pilot also executed a missed at or above DH every flight where marginal visibility was right at the DH." Well that explains a lot! He also told me that I should have been able to see the runway in all the IMC scenarios. My response was "That's fine, but I'm not pushing MDA/DH in any of *my* flying - fancy PFD or not." I'm now kinda glad that's on tape. "Oh, one other question," the researcher stated. "Would you be interested in coming back around March '05 to participate in the second phase of this experiment, to be conducted while piloting NASA's Cessna 206 equipped with these PFDs?"

Very nice writeup Peter. Thanks for sharing. Man, I'd jump at the
opportunity to participate in something like this. Good for you in sticking to your guns and executing a missed approach when you did. -- Jack Allison PP-ASEL, Wanna-be IA Student "When once you have tasted flight, you will forever walk the Earth with your eyes turned skyward, for there you have been, and there you will always long to return" - Leonardo Da Vinci (Remove the obvious from address to reply via e-mail) |

When I want to take video I set the camera on the top of the panel on an
unused sponge. I have a couple of elastic straps that hold it securely to the sponge. No image stabilization needed. I set the camera to the landscape setting so it won't focus on the windshield, it focuses on infinity. It is much easier with a camera with the swing out window. I adjust the camera up and down in such a way that the engine cowl is just barely showing on the bottom of the screen, camera fully zoomed out. I also have an audio cable that goes from one of the headset jacks to the cameras mic in jack. Works like a charm except for there being no engine noise on the film. Works really cool when you put it on a DVD with music in the background. John T wrote: "Jay Beckman" wrote in message news:2WAdd.7321$SW3.1273@fed1read01 How do you mount your video camera?
