I am sure about it, and I was describing how it works. I fly DJI aircraft regularly in TFRs. For all the ones that I've worked in the Geo zone coincided with the TFR, but then I generally create circular TFRs for simplicity.I'm not so sure about that Sar. The blue area is much larger than the actual TFR or has been in my experience. I have Foreflight that shows the actual TFR and naturally I haven't actually ever dared to get really close to it because of all the warnings I get even though I'm flying with authorization which allowed me to take off. I think in the case of a fire TFR DJI makes the blue area so large because the TFR is probably going to move or expand. It has been my belief that if I accidently entered the the actual TFR my drone would land. ....I'm not about to try and find out
We have many TFRs pop up around here.,, Presidential, Forest Fires, Celebrity Helicopter crashes and ignorance is not an option with the Friendly FAA.
But they can be any shape, and for non-circular TFRs I would expect DJI to implement a circular authorization zone that covered the entire TFR.
