When automation fails — transcript

00:00:00.500 --> 00:00:04.706 When automation fails: what the system does, and what you do.

00:00:06.400 --> 00:00:09.812 An automated system works for long periods without human help,

00:00:09.812 --> 00:00:13.767 moves around on its own, and avoids harm to itself, people and property.

00:00:16.400 --> 00:00:21.613 The parts: IMU, GPS, flight controller, link and ground station.

00:00:21.613 --> 00:00:26.666 IMU and GPS are fused for stable flight. You stay responsible.

00:00:27.400 --> 00:00:30.675 Program a mission and it flies itself, waypoint to waypoint.

00:00:30.675 --> 00:00:34.166 That cuts your workload and frees up your situational awareness.

00:00:38.400 --> 00:00:44.299 Use it to watch the telemetry. Battery voltage and satellite count matter most.

00:00:44.299 --> 00:00:50.051 Look for deviations from the plan, erratic control, or unusual battery drain.

00:00:50.401 --> 00:00:55.505 Automation has limits: bad weather, weak GPS near buildings, link interference,

00:00:55.505 --> 00:01:00.928 sensor blind spots, battery life and the rules. So a skilled pilot stays on standby.

00:01:02.401 --> 00:01:07.228 Find faults early. Run diagnostics before launch, watch telemetry in flight,

00:01:07.228 --> 00:01:11.178 and review the logs after, comparing planned and actual paths.

00:01:12.401 --> 00:01:16.841 Quick check. An unfamiliar error appears during pre-flight. What do you do?

00:01:17.601 --> 00:01:19.690 Don't launch. Look the code up first.

00:01:21.401 --> 00:01:24.927 Mid-mission, the drone flies behind a building. The link drops.

00:01:26.401 --> 00:01:30.162 A correctly set failsafe takes over, and the drone heads home.

00:01:32.401 --> 00:01:37.498 Return to home triggers on lost link, low battery, or your command.

00:01:37.498 --> 00:01:42.745 It climbs to the RTH height, flies home and lands. You can cancel it.

00:01:44.401 --> 00:01:49.627 Set RTH height too low and it flies into the obstacle. Take the highest obstacle,

00:01:49.627 --> 00:01:52.368 say forty metres, and add at least twenty.

00:01:55.401 --> 00:01:59.998 GPS lost. The drone drops into attitude mode and drifts with the wind.

00:02:01.401 --> 00:02:04.352 Take manual control and land it as soon as you can.

00:02:06.401 --> 00:02:10.952 No GPS means no position hold and no waypoints. It drifts. Take control,

00:02:10.952 --> 00:02:13.819 land as soon as possible, and alert the crew.

00:02:16.401 --> 00:02:20.026 With an IMU failure, the autopilot makes bad corrections.

00:02:20.026 --> 00:02:24.838 Switch to the most manual mode, land quickly and safely, and alert the crew.

00:02:26.401 --> 00:02:30.239 Before you launch: check every waypoint and height, the home point,

00:02:30.239 --> 00:02:34.472 geofence and failsafes. Confirm airspace approval, and run a trial flight.

00:02:38.401 --> 00:02:43.077 Automation helps. You monitor it, know its limits, and take over when it fails.

00:02:45.401 --> 00:02:50.965 Final check. Mid-mission, an IMU failure warning appears. What do you do?

00:02:51.315 --> 00:02:54.084 Most manual mode. Land quickly and safely.
