AI flight report

This flight (arducopter-h743-field-flight) began at 2021-06-13T04:40:34Z and lasted 19:35 (1,175 s). The vehicle auto-armed, took off about 0:40 into the log, and spent almost the entire flight in LOITER (19:29) before switching to LAND for the final 6 seconds; disarm and landing complete are recorded at 19:33. The track distance was 2,676 m, the farthest point from home was 198 m (at 17:29), and the average moving speed was 4.0 m/s with a maximum ground speed of 12.1 m/s (at 17:00). GPS quality was good throughout (minimum 14 sats, maximum HDOP 0.80). Weather from the archive was clear, 11.6°C with a light WNW wind about 3.29 m/s.

Altitude rose quickly to the recorded maximum of 26 m above home at 1:59, then the vehicle spent most of the flight loitering between roughly 9–21 m AGL with occasional descents to very low height (as low as 0.5 m AGL around 14:45 in the downsampled telemetry). Vertical performance shows occasional relatively brisk climbs and descents (summary values: max climb 2.5 m/s, max descent −2.6 m/s). There were also multiple brief speed bursts later in the flight (several samples above 10 m/s around 16:45–18:00), consistent with deliberate repositioning or brisk translational maneuvers while still in LOITER.

The main anomaly recorded was a HIGH_VIBRATION warning (>30 m/s²) at 17:59 into the flight (warning severity). That vibration alarm occurred after the periods of higher ground speed and just before the operator commanded LAND at 19:29. Likely causes include propeller imbalance or damage, a loose motor/arm mount, or something contacting the airframe, but this is a likely explanation rather than a confirmed root cause. I also note that battery percentage and voltage fields are not present in the downsampled telemetry supplied, so battery state cannot be assessed from this summary. Actionable recommendations: (1) inspect and balance/replace propellers, check motor mounts and fasteners, and review the full high-rate vibration (raw IMU) logs to locate the frequency/source of the vibration before the next flight; (2) enable and verify battery/power-module logging if not already recorded so voltage and remaining capacity are available for post-flight checks.

Detected flight events

1. 0s — Flight mode changed to LOITER

   00:00 — Mode set to LOITER: GPS position-hold engaged so the quad can maintain location and altitude for stable testing.

2. 0s — Vehicle auto-armed

   00:00 — Vehicle auto-armed, allowing motors to spin and the aircraft to be ready for immediate takeoff.

3. 40s — Takeoff

   00:40 — Takeoff initiated; aircraft climbed thereafter, reaching the flight's peak altitude later in the profile.

4. 1m 59s — Maximum altitude: 26 m above home

   01:59 — Maximum altitude recorded: 26 m above home — a low-altitude field flight, well within expected limits.

5. 17m 0s — Maximum ground speed: 12.1 m/s

   17:00 — Maximum ground speed reached 12.1 m/s, observed during the later high-speed legs of the mission.

6. 17m 59s — High vibration (>30 m/s²)

   17:59 — High vibration warning (>30 m/s²). Likely related to the earlier high-speed / dynamic flight; inspect props, motor mounts and frame for imbalance.

7. 19m 29s — Flight mode changed to LAND

   19:29 — Mode changed to LAND, initiating a controlled descent (telemetry shows descent around this period).

8. 19m 33s — Vehicle disarmed

   19:33 — Vehicle disarmed: motors disabled and aircraft secured on the ground.

9. 19m 33s — Landing complete

   19:33 — Landing complete and flight concluded; total logged duration 19:35 (1,175 s).
