I wonder if the action depends on the class of airspace, when I get to 5 miles from a small private/military trainer airfield I get a warning and the drone stops dead, but doesn't land
I think the firmware and NFZ databases are flawed.
You are right, if you are approaching a red NFZ, the drone should stop and not enter. I have seen that happen as it should.
Here is what I think based on my observations with auto land. Here is where I fly. I am the red dot:
With GEO on, I get prompted to unlock the yellow zone, which I do. After taking off, after a certain amount of time (and I think this is a consistant amount of time, like 30 seconds, but I have never actually timed it), the drone prompts for an autolanding. During the autolanding, I can still manuver the drone, and if I throttle up, it will actually fight the landing (I have to put like 80% throttle for it to stay level). If I move out of the yellow zone, and in the green zone (an "enhanced warning zone"), the drone will not take off at all (says I am in an NFZ).
This tells me that there is a logic problem with the software when I am in the yellow zone. The drone/app lets me unlock and take off, because I am in a yellow zone, but at some point later on, a process on the drone realizes it is in the "enhanced warning zone" and starts to force a landing. It seems like the process checking for being inside a warning zone runs only every X amount of seconds.
I have been told by DJI that the "enhanced warning zone" around DC is special, and indeed broken on the P3P/A, but I really have no idea why it exists around DC. They will unlock it for you, but you have to have an iOS device. Further, the "enhanced warning zone" is put in place by DJI, and not the FAA. Take it out DJI and free my drone!
