AI flight report

The flight lasted 1:53 and covered 527 m over ground, reaching a maximum altitude of 50 m above home and a top speed of 8.6 m/s (recorded at 1:10). The aircraft flew out to its farthest point, 244 m from home, at 0:41. Conditions were mild — 19.3°C, overcast, with a light 2.77 m/s wind from the SSW — so weather is unlikely to have been a major factor. After arming in MANUAL, the vehicle switched to AUTO_TAKEOFF at 0:06 and climbed quickly, hitting 43.9 m by 0:15 and its 50 m ceiling at 0:18. It held roughly that altitude through 0:30–0:45, then descended steadily — 34.5 m at 1:00, 19.5 m at 1:15, down to essentially ground level (1.9 m) by 1:45 — before disarming at 1:52.

A few things in the log stand out. Right at the start, at 0:00, there's a warning that the barometric and fused (GPS/INS-blended) altitude estimates disagreed by 167 m, and the derived diagnostics show this gap peaking at 170.1 m around 0:18 — the same window as the climb and the reported maximum altitude. Since these are independent altitude sources, a gap that large means one of them was wrong during the climb-out; it doesn't necessarily mean the drone was ever actually 170 m higher or lower than logged, but it does mean the 50 m max-alt
