We are going through a BVLOS certification process and regulators want me to solve this question:
- Suppose the autopilot software or hardware crashes or becomes unresponsive, and for some reason the aircraft keeps its PWM outputs on and starts a fly away. How would you terminate the flight?
Our setup is a hexarotor running Cube Black with a companion computer with dedicated battery and a parachute that opens autonomously after detecting a fall. My understanding is that the regulators wants us to kill the aircraft by cutting power to the autopilot or cutting power to ESCs, or blocking PWM signals to ESCs.
With an unresponsive autopilot scenario, there is no point in trying to send commands from the c.computer or switching modes. How would you solve this? Is there any way to externally to externally reboot the autopilot, or cut signals to ESCs? @philip
Hope you can help me with this one.
