AI flight report

This log records a GPS track that began at 2020-05-23T12:01:56Z and ran for 16 days 13:06:07 (1,429,567 s). The track originates from home position 57.85572, 26.13747 (home elevation 76 m MSL) and covers 3,962,251 m total distance. Average moving speed was 2.8 m/s (max ground speed reported 2.8 m/s at 5d 14:29:28), and the farthest point from home was 266,911 m reached at 6d 14:28:56. A historical weather snapshot attached to the flight shows clear conditions, 16.5°C and a light SE wind of 1.58 m/s — this is likely the environmental snapshot near the start of the recording.

Altitude varied widely during the record: the highest logged altitude was 223 m above home (event at 2d 21:05:10), and the sampled telemetry contains many negative altAGL values down to about -72.8 m (e.g. 7d 17:18:52). Vertical speed extremes in the summary were a maximum climb of 3.9 m/s and a maximum descent of -2.9 m/s, but most sampled vertical speeds are near zero while horizontal speed stays near 2.8 m/s, indicating generally slow, steady motion with occasional climbs or descents.

Notable events in the file are limited to an initial TAKEOFF recorded at 00:01:29 after the log start, the MAX_ALTITUDE event above, and the MAX_SPEED event; no warning, error, or failsafe events are present in the provided list. Several telemetry fields are missing or unknown in the downsampled table (battery percentage, voltage, satellite count and hdop are marked “?” and the flight mode is listed as UNKNOWN for all samples). The repeated negative altAGL readings are unusual and are likely caused by a reference mismatch (home elevation vs. track altitude reference) or GPS altitude offsets rather than implying physical travel well below ground level, but that should be confirmed.

Recommendations: first, capture complete telemetry next time — enable and record battery state, voltage, satellite count/hdop and flight/mode information so performance and safety can be assessed without gaps. Second, investigate the altitude reference (home/track MSL vs AGL) and confirm whether the long-range movement (farthest point ~266.9 km and nearly 4,000 km total track) was planned; if not, review geofence and mission planning or tracking configuration to prevent unintended long-distance excursions.

Detected flight events

1. 1h 29m 7s — Takeoff (altitude threshold)

   Takeoff detected at 1:29:07 (altitude threshold): this marks the climb initiation from home and the start of the recorded airborne segment.

2. 69h 5m 10s — Maximum altitude: 223 m above home

   Reached maximum altitude 223 m above home at 2d 21:05:10 — the flight’s highest point (telemetry shows ~197 m before and 125 m after), important for clearance/ceiling checks.

3. 134h 29m 28s — Maximum ground speed: 2.8 m/s

   Maximum ground speed 2.8 m/s recorded at 5d 14:29:28 — this equals the flight’s average moving speed and the overall max, indicating consistently slow GPS-track movement.
