HFD,
You saw the definition in an FAA document
Ah, thanks!
I hope we're all agreed that only a fool flies an aircraft outside it's POH
Absolutely agreed. But I think you missed my point - all I was trying to do was point out that there are legal documents (e.g. the POH) which make reference to "aerobatics", therefore it's not valid to say that you can't ban aerobatics because there is no legal definition of aerobatics.
