starting the tail engine on an empty Trislander, then landing, shutting down the wing engines, loading and leaving. But even that sounds like a stretch!
I have only three hours ICUS in a Trislander; But I definitely call BS on that one!!!!
International Trader; Let`s have some names, dates and a/c types involved (PM if you like) but I still call BS.
I heard the story of someone doing the excercise you described in a BN2 when I was in PNG, and even the teller of the tale said that in his opinion it was BS.
