My focus was on DJI zones. Please re-read my last post in that context. If you look at OP's first post, you'll see he ended up in a DJI blue authorization zone, not a red restricted zone.Nothing to do with US regs here Dan, as far as I'm aware the average hobbyist doesn't have the systems to unlock anything either.
You can get into the NOTAMS and local field thing, but most don't have to.
As mentioned, while we have the red total NFZs / approach / departure areas etc, where you virtually can't even spin the props, in these uncontrolled airport / heliport orange zones, you can fly to our legal 120m, but must land if you become aware of manned aircraft operations.
Normally anyone with a DJI account can self-unlock a DJI blue authorization zone. Unfortunately that's not yet available for the Mini.
And yes LAANC is available to hobbyists.
