Following on from the safe outcome of the Speedbird 9 all 4 engines failure in 1982, having encountered volcanic ash, we were taught a similar no-engines visual circuit and landing per the Hunters in the BAC-111 simulator.
The overhead key was 8000' and 220 kts. If you could make that we were shown that you could continue downwind, reducing speed and height while running some flap until you were short finals. Then and only then you dropped the gear and flared for a "Shuttle" landing.
I never had to try it in anger, I'm glad to say, but given that the sim never really simulated the actual aircraft that well, it gave you a sense of confidence that if you could do it in the sim, you sure as hell could do it for real!
