and for the sim sessions I recommend to do it as your instructor says you should.
It is certainly comforting to have such blind faith in your simulator instructor. If you are saying do as you are told just because the instructor says so and you need to keep on the good side of him, then fair enough in your advice. That is entirely different from receiving accurate technical advice.
On the other hand believe it or not, simulator instructors come in all shapes and sizes and some are very knowledgeable while others are ... not.
