I don't think a pilot can operate as cabin crew without some sort of extra training. Their SEP training is abbreviated and refreshed infrequently
Given the airline specific context of this thread (BA) can please stop that rumour in it's tracks, for BA at least?
BA Flight Crew I believe
do SEP renewal: e.g. door operation ( manual and automatic etc,) slides, lifejackets, etc etc etc much the same as the Cabin Crew and just like the cabin crew it's normally done annually. No idea how other companies handle it.
OTOH BA Flight Crew don't do the annual
medical training/refresher the BA Cabin crew do, but they do some annual Flight Crew specialist stuff the cabin Crew don't do.
