I would hazard a guess that if you're using the notional weights of either 70/80kg for a male, 60/70 for a female and 20kg for baggage including the hand or lap stuff, that your load sheet will always be pretty much a fabrication.
So it's midgets all round and don't throw them around the room or you'll be out of the rugby like old Mr Phipps, Zara's room mate. Mind you, he at least got a second chance. As for such matters as weight and EFATO in a one engined wind up, glide speed stays the same as I recollect from my days teaching the forces. So what has happened these days to the EFATO airmanship field that all pilots used to predeterminedly select in case of an EFATO and practice getting into as well. Gosh, anyone out there remember, was it 35 at FAGM, the one with the mine dumps? Not a place for sissys at night in a one engined plank.
