To me, the whole concept is ridiculous. The nature of flying a fixed-wing RC plane LOS is very different from flying a drone with a camera. Ignore what all the rules say for a moment, and just think about
how you enjoy
flying your drone.
If the drone hobby reduces to flying in comparably small areas over a big clearing, the "hobby" will end.
I could lazily fly my Gentle Lady back and forth over a length of coastal cliff maybe a hundred yards in either direction, and really enjoy it.
Replace the glider with an
Air 3 but fly the same confined area, I'm bored in about 5 minutes.
FRIAs makes sense for RC planes and helis. They make no sense for a camera drone with all the flight assists a typical DJI drone has.
