...

1. Wires disconnecting

2. Boards shorting

3. static electricity (possible ground plane)

4. Inclement weather during flight (limit flight window)

5. Antenna Brownout → drone altitude hold, antenna pattern search → fatal failure.

6. hardfault (failover)

7. Batteries not charged

   1. batteries discharging past safe levels

8. Arc short

9. Overheating & auto-shutoff

Software Failures

1. Sens failure (glide)

2. autopilot failure (pilot takeover)

3. fly by wire failure

   1. lost AHRS // no inertial nav → fatal failure

   2. incorrect command deciphering → pilot disarm / takeover → fatal failure

   3. control surface output inverted. → pilot disarm/takeover → fatal failure.

4. telemetry lost (follow VFR & divert)

   1. telemetry modem failure

   2. board modem module failure

   3. software manager failure.

5. controls/PID failure

   1. incorrect PID values

   2. controls runaway (I term runaway?)

   3. flipped motor direction

6. RC link lost (divert and glide)

7. Landing Pad not found

   1. search → find?

8. heading lost

   1. see 3, 6.

9. RF Interference from other teams/environment

...

• improper site assessment

  • flying into obstacles // not being aware of restricted flight areas

• improper communication

• heat?cold?

• dehydration
