The AF simulator was regarded as a sub standard machine, never had the required interface or processing power compared the the UK machine that was built as a joint effort by Sinker-Link Miles (structure and motion) and Redifon simulation (interface and computers), with a view that the developed product would be offered to the option holding airlines.
A key failing of the AF machine was that it could not correctly simulate an engine failure on take off without going off the runway.
So what happened when AF had an apparent engine failure/fire after V1 in 2000? The crew made a right hash of the procedures....Nuff said really.
