@PhillipG: There is not an approved demo flight routine for US F-35s. That is the case for now, as it was two years ago prior to the F-35A flailing itself to death on the runway at Eglin. Last year at Oshkosh, the F-35As flew an arrivals routine, and an extended taxiing routine to the parking stand (that was unintentional: the pilot got lost - so much for sensor fusion.)
Whether or not the UK F-35 will have limits, IDK for sure, but I think the follow whatever the JPO decides/allows.
