Should the former be a synonym of the latter, and faa to be used with the latter if needed?
It was suggested in chat that:
it sounds like faa-approval needs help then, because I suspect the former would make more sense for things the FAA has to supply approvals for specifically via LOA, OpSpec/MSpec, and so on
If that's the case, I think a better jurisdiction-neutral tag would be preferable, suggestions?
a: "The essential permission for a pilot to be authorized to operate an aircraft in US airspace."
