Extensions to DJI red bowties (unlocking)

[Chuckinay]

This a question for those who do a lot of self-unlocks for restricted (by DJI) airspace ...

What is the classification of the extensions on red runway zones — the apparent extension that creates a true "bowtie"? I can't tell what color they are — it doesn't seem to be blue or red. Do they fall into one of the four restricted-zone classes, and if so, which one?

All I can say mine are blue out in the same situation, but I can tell mine are blue. Looking at DJI FlySafe Map...it is a altitude zone restriction.

Grey is altitude restriction zone. You'll often see this on the outskirts of the runway, following what FAA facilities map shows.

OK, thanks. I wonder why they extend out 10 miles from the airport, well beyond the FAA grids.

Thanks for sharing that extended list. I only knew of four zones previously.
