Thanks SS, that has nightmare scenario written all over it - is there a way of overriding the pilot selection (say it is set to idle accidentally) from the instructor's side or does the pilot's switch have to be physically moved back to FLT requiring a changing of hands by the instructor?
If you visit YouTube now and then, search Nick Murray's channel and he has a great video of intro and flying the 505... some great stuff, some very scary stuff (to me).
