Re: Failsafe?
While the public tend to think of a drone as as a multi- rotor device, typical the four armed quadcopter ie what a DJI model looks like, the CAA don't make a distinction. To the CAA a Drone is any remotely piloted aircraft or unmanned aerial vehicle (RPAS or UAV).
The fact its remotely controlled in real time (as this was) or autonomously following a preset flight plan makes no odds to the CAA definition.
