This was an interesting day...
I went to the hangar knowing that the winds were directly across the runway today. It's been more than a month since I flew the Airbike due to weather, so I committed to making this a crosswind training exercise.
Right before take off, I called the automated weather service at Wichita Mid-Continent Airport [a few miles NW of Selby (my location)]. The wind was 270 at 10kts, gusting to 13. I was using runway 35, so my crosswind was from the left at 9.8kts (11.3mph).
First circuit: I felt the wind trying to lift the left wing quickly, so I gave it a bit more aileron. When the tail came up, it got pretty squirrely, but manageable. I chose a soft-field routine and got the wheels off the ground pretty fast--stayed in ground effect until I hit 45mph and started my climb out. The wind hit hard from the left at about 50feet. I was crabbed to at least 30* as I went due north. I made my right turn and came back around climbing to 500AGL for a tight pattern. I made my approach for landing slipping to stay in line with the runway. Throttle was need to maintain altitude. Speed was about 50mph to allow for gusts. The landing was a solid three point, but it again got squirrely on the ground during roll out.
Second circuit: This take off was similar to the first. The landing was worse because I forgot the gust factor. I had too little airspeed and touched down sooner than I anticipated. I bounced and transitioned into a wheel landing with forward stick. 'Whew...' Salvaged that one!
Third circuit: Take off was scary! the wind impact that had been hitting me on the left at 50 feet, hit much lower this time. Wheels came up, and the plane went left. I crabbed and was having trouble climbing. What I should have done, was turn left (into the wind) to get some quick air speed. However, I turned right. The gusts were hitting really hard from the rear as I tried to climb. It was as if the winds just took all of the air off of the wing. I was struggling to keep it above stall and could not climb. I was at about 100-120 feet. I leveled and rode out my crosswind leg a bit longer before turning on the downwind leg. Once I was on a heading of 170, the airspeed climbed quickly. My last landing was similar to the first with a bit more effort to keep it straight. Much more throttle was needed this time, and I didn't cut power until I was past the white tires (end markers).
I did three circuits. When I got out of the cockpit, I checked the wind again. It was 280 at 10kts, gusting to 15. That's 9.4kts crosswind (10.8mph).
Page 17 of the Airbike flight manual lists the maximum crosswind component at 10kts or 12mph. I was glad to prove that today and my confidence is duly bolstered. That being said, it was not a pleasure flight by any means. I need a beer.
I borrowed a friend's Go Pro camera. Here is the video: http://www.youtube.com/watch?v=nslaJSnJWhI
