Does the 500's manual explicitly prohibit aero's? What is the outcome of a display like this with clear full loops? Would the aircraft be grounded as it's gone outside it's flight envelope? I think that happened with the B407 that was looped and rolled at Virginia Airshow, South Africa in 2004/2005. Is there an EASA definition for heli aerobatics? I know similar has been had before
here but just curious about all the G-REG civvy helicopters that display doing wingovers, stall turns, freestyle etc...
