Interesting. I too was at APATS and I didn’t quite get the same message with regards type training and there is the regulatory issue but I agree that there was a strong message put across for ‘professional simulator instructors’ within MPL, however with regards your comment “But, is it essential that a simulator instructor to have flown in command on the type of aircraft (simulator) on which he hopes to teach? Ideally, yes. But essential? I don't really know about that. Appreciate your comments” No, it is not essential to have flown in command and in fact many of the younger SFIs we see here are in fact SFOs in their day job. This relieves the pressure on the Training Captains whilst providing invaluable experience to the up and coming trainers.
A good conference though with some very positive messages for a change.
