Simulate a fault

If something goes wrong

RC signal lost
Level descent at 0.75 m/s until touchdown is held for 1.5 s, then disarm. RC back for 500 ms returns control. Capped at 120 s.
Barometer dead
No climb loop, so motors cut immediately.
Battery critical
Always an immediate cut.

The navigator sends targets, not motor commands. The flight controller bounds them, and a stale target (over 60 ms) falls back to RC.

Recording saves MKV on the companion computer. Stream and recording keep running if the link drops.

One board, two computers. If missing a deadline by 10 ms could crash the aircraft, it runs on the pilot.

Decides where to go

{{ o }}
No deadline. May crash, and the aircraft keeps flying.
Link loss is normal
Guided targets go stale and control falls back to RC.
No software arming
Arm requests over the link are ignored. Arming needs the physical switch.
Boot order doesn't matter
The pilot is flight-ready about 30 s before Linux.
