101.025
Meaning of populous area
For this Part, an area is a populous area in relation to the operation of an unmanned aircraft or rocket if the area has a sufficient density of population for some aspect of the operation, or some event that might happen during the operation (in particular, a fault in, or failure of, the aircraft or rocket) to pose an unreasonable risk to the life, safety or property of somebody who is in the area but is not connected with the operation.
So further out to Sea, and actually closer to civil aircraft, in the instance of the Q1 quad copter at least helps it to further comply with 101.025?
