Airshow Permit?

[poadeleted20]

What do you consider "the public"?

It's not "the public," it's "the invitation." If you advertise publicly that there will be an air event, and you have an aerobatic display at the event, you need an FAA waiver. At the other extreme, if someone just happens to be practicing in the box, and folks driving by see it and stop, that doesn't count. Between those two, the "duck test" applies.

If there were people there eating free a lunch, and two airplanes flew over the airport in formation and then flew around the pattern and landed in formation I simply do not see how that would require a waiver, aerobatic card, or formation card.

Only if they pattern was flown knife edge or inverted (aerobatic) below the customary floor (what is it.. 2000 AGL without the waiver? my memory escapes me),...

For aerobatics, it's 1500 AGL (91.303(d)), but the presence of an "open air assembly of persons" also requires a waiver for aerobatics (91.303(b)).
