Flight report

Jay Scheevel

Took a flight this morning to check out my service ceiling. Sam mentioned that he thought I should do the service ceiling test during his comments at my hangar tour in April. I had filled the O2 bottle anticipating coming to Kevin’s fling in May and I never made it there, so I had some oxygen to experiment with. Took off with about 15 gallons of fuel and only me on board. The takeoff was at 6100’ DA and it got off smartly in less than 1500’ of runway.  I kept climbing steadily between 500 and 300 fpm showing around 105-110 mph IAS or around 125 TAS. Got up over 15,800 feet pressure altitude, and when it  slowed down, I grew bored of climbing at only 100 fpm, so I terminated the experiment. That was about 17,700 Density altitude, so I think I could climb to 18K pressure altitude on a standard day if I wanted to. At this point I pushed the nose over and got it trimmed up to fly level at a little over 15,800 PA. I was able to indicate 107 mph, which translated to 141 mph TAS and I was burning less than 4 gph! The wind was from the SW at 29 mph, so if I had turned to the NE and headed over the hills, I would have had minimum 2500’ feet clearance over the highest peaks and done 170 mph ground speed…at 4 gph, that would be very economical. The aircraft handling was solid during the entire flight. Controls were always agile. Also, the powerplant ran flawlessly all the way up and back down with no hesitations, roughness, heating/cooling problems, etc.


My conclusions: This airplane will do anything that I require it to do in order to fly safely in my high altitude environment, and I am very happy with the performance overall. Also, had a nice landing at the end. Smiley face. 😊
