I just did my 5 hour glide for silver/gold duration. My Colibri II's IGC file, as reported in SeeYou PC, shows the correct Takeoff time, Begin soaring time, Landing time, Duration, but then claims a Soaring End time 2 hours 42 minutes into the flight which was actually 5 hours 15 minutes total. It then claims an Engine time of 00:02:08 which does not relate to anything. Especially the fact that our Cirrus does not have an engine. The time on tow was 2 minutes, 27 seconds.

The IGC trace in SeeYou appears complete and uninterrupted when I zoom into the exact time that it claimed soaring ended.

Any ideas? This Colibri was new this year and it's the first flight of about 9 that shows a problem. I have it fairly well exposed to the sky just above the canopy frame by the vent window. I wonder if wind buffetting near the unit could triggered engine run. ... Aaron
