Let’s say I’m launching from a building that is 200m within the 150m altitude zone. Will my drone even fly at all?
I asked a similar question here a while back which got 0 replies.
What happens if you accidentally enter an altitude restricted zone (60m max) at above the set max height (say 100m)? Or is it not possible to enter into these zones above the set max altitude at all? Just curious. Also, can altitude zones be unlocked?

I understand why it got no replies; it was a stupid question. You can not enter, mid flight, an altitude zone at above the set altitude limit.But yours is a more interesting question since you are not entering the altitude zone mid flight but taking off inside it. Can you even take off while you are above the set height ceiling? It all comes down to what the drone considers ground here - your take off location on the top of a 200m building? Or the actual ground?
I don't know the answer definitively. But, I would hazard a guess that since altitude zones are based on height from ground, and dji drones take the take off location
to be ground (
0 altitude), you would still be able to take off with in an altitude zone at above the set height ceiling and fly up vertically up to the height limit set in the altitude zone. Having said that, it is also possible that the drone can realize it is actually 200m above ground, instead of
on the ground, from GPS signals since altitude can be extrapolated from GPS data. It also has a barometer onboard, that is another source for altitude data. If the drone uses one or both of these two to determine where it is relative to the ground at or before take off, may be it will refuse to take off in the first place or auto land immediately. All guesses of course, surest way to find out definitively would be to try
P.S.: I love what if scenarios, but I am the last person to speak with authority on any of the topics I comment. I have more curiosity than knowledge in any subject matter. So, don't take this as sound advice.
