With GEO OFF there is no way you can start inside or enter a RED no-fly zone radius or any restricted area. It is not a pilot's decision. As a commercial pilot (helos) I understand that and agree if you are dealing with unqualified flyers . . but there are valid reasons to be able to do that sometimes.
Looking at this image I could start and fly in this location but the P4 will slow and stop if you attempt to go towards the zone. The other side of the barnyard the P4 will simply not start. This precluded this farmer from ever getting images or crop information from more than half his farm while his neighbour next door is unrestricted even though, as he says "This farm was here long before the %#*! airport. . . now they think they own me" . . . I can get the proper clearances for him and use different aerial camera I guess . . . but dji no way! . . easier to get a gun at a swap meet.
I think authorities are just over reacting to the new technology and not willing to "think outside the cylinder" . . . or consider deviating from "NO!". . . somewhat understandable if you are the one doing the authorizing . . .so not allowing a human decision is about all they can handle for now. Hope things evolve sooner than later.
