Wrong for fixed wing has always been pretty standard for helicopters! Not that I know ALL helicopters, but I can’t think of another one with PIC on left! As I’ve said, we almost always take a helicopter tour when available and pretty much for ever, certainly for over 40yrs, that is how it has been. My first helicopter ride would have been a Hughes 600 back in the ‘70s and since then, Bell 47, Jetranger, Longranger, Squirrel and R44, all right seat PIC, plus one on the Barrier Reef that I can’t identify, Bell of some sort I think.p
