Training
Link Trainers did not attempt to simulate any ONE kind of aircraft. It was used to train many thousands of pilots in what it COULD do, teach and then PRACTICE some aspects of flying on instruments.
At that time, there was nothing better.
The Stratocruiser simulator had a model landscape with a "small" television camera, which then moved in sympathy with the pilots inputs to give a visual image, initially for the Captain, probably in black and white !
The point that I was trying to make, was that PF, (any PF ?) might have made a better show, if he had had practice. I do not know how many hours a year Simulators are used, 3,000, 4,000 or 5,000 hours - or more ?
If some bean counter queries the cost, just say 447.
