H500, I like very much your arguments about not announcing failures. Both HC and myself have been lucky that we were able to do just that in an FFS, thus completely mitigating the safety issue. I think that is one of the reasons EASA-FCL requires recurrent training and checks to be done in the FFS. I sympathise with the smaller helicopter world where this is not available.
Having said that, training in the FFS will never build the same degree of confidence as doing it in the Helicopter. What you are doing, pound for pound, is ultimately probably more beneficial for the student than the FFS, accepting of course, that the aircraft is limited in the failures you can reproduce.
A big respect from me for your honesty and the positive approach you have taken from what at times, has been harsh critique from me. I would like to be trained by you! I don't ever say that lightly.
