This training is woefully inadequate in the civilian comercial world.
You may wish to look at how the RAF Central FLying School teaches pilots to recover from Unusual Positions both visually and on instruments as it is very good indeed. They are taught right from the begining of training and practice it regularly so it is instinctive.
You may also like to look at the King Air incident out of Glasgow a few years ago for a good example of how not to do it.
