A TODO before the comp: Save the configuration profile to the ground station so we have a backup before any big modification to flight profile.

The flight readiness review requires the following:

All UAVs must be equipped with a safety flight termination system that can be activated either automatically or remotely (kill switch). […] For rotary wing, a quick vertical descent of a minimum of 2 m/s and touchdown must be performed. The flight termination mechanism must be operational at all times. If the flight termination method is not working, the aircraft must terminate the flight itself automatically and rapidly. [...] Aircraft must be in termination mode within 10 seconds of the termination function being activated

That is:

• A disarm switch

• Lost link failsafe, triggering within 10 seconds

• Immediate landing at a minimum speed of 2m/s when triggered

The landing mode can be configured to meet the landing speed with the parameter WPNAV_SPEED_DN=200(cm/s). It is likely sufficient that the LAND_SPEED stays at the default of 50cm/s (below 10m the aircraft uses LAND_SPEED instead of WPNAV_SPEED_DN).

The failsafe should be triggered when GCS and Radio are both disconnected.
