BOAC:
- I really cannot believe I am reading that. Whatever fancy name it gets, it has been around for decades (used to be called 'disorientation'). It is not 'complex' nor should it need to be 'taught in the sim' (nor, I suspect, can it be). It should be a basic keystone in every pilot's ACTUAL training, especially for those who go on to fly without external visual reference. That is what the 'instruments' are for and they are what pilots should be told to use.
I recall it was called Attitude Instrument Flying for many decades.
