AI flight report

This flight lasted only 22 seconds and covered just 22 meters of ground track, all in POSCTL (manual position-hold) mode. The aircraft climbed to a maximum of 5 m above home at 0:12, reached its farthest point of 10 m from home at 0:13, and touched a top ground speed of 5.6 m/s at 0:11. Conditions at the time were 26.1°C with a 6.04 m/s wind from the SSE and moderate drizzle — a fairly breezy, wet setting for a fixed-wing test hop this short.

The log shows trouble almost immediately. At 0:00, before the flight really got going, the barometric and fused altitude estimates already disagreed by 11 m, a sign that one of the altitude sources was off from the very start. Then at 0:11 a cluster of critical events hit within the same second: the steepest early attitude (51° from level), the flight's peak acceleration (6.6 G, logged as an impact/hard-landing event), the top recorded speed, and the first failsafe activation. Oddly, a "takeoff" threshold event is logged right after this, at 0:12, meaning the impact and speed spike came before the system recognized a normal climb — consistent with a bounce or hard contact rather than a clean liftoff. A second impact (4.7 G) followed at 0:16, and at 0:17 the aircraft recorded its most extreme attitude of the flight, 169° from level — essentially inverted — coinciding with a second failsafe trip. Satellite count dipped to its lowest (13) at 0:18, and by 0:20 the barometric-vs
