I think I will continue to avoid the R22!
EOLs should be a regular part of training - 2-3 at the end of every dual trip from the begining. Obviously the early flights will be demos until later in the training. By the time GFTs are in sight the instructor should feel confident in the student's ability and the student should by then have become confident in this exercise so it is no longer a "big deal".
Simulated engine failure should also be practised more than once on every dual trip. Gradually the "surprise" factor should be introduced until the student knows that if his hand is off the collective........
If you do not feel comfortable about EOLs you should not be flying a helicopter and certainly not with pax.
