I can remember having a FJ instructor at 2FTS and that turned me off FJ for life. I remember asking him questions in debriefs and I all I got back was icy contempt. Oh, and he gave out scores that were always 2 lower than anyone else. I gave up asking him anything.
Basically, this guy thought that instructing and the PC9 were beneath him and he went out of his way to upset everyone around him. His attitude was appalling.
It seems to be that most of the instructors at BFTS and 2FTS come from a multi-engine background and until there are more FJ role models in the training system, who properly mentor and encourage their students you will find that the graduates will still prefer the big heavy jets.
By the way, I am a realist and I know this will never change (for a whole number of reasons) and we will never see lots of happy Hornet pilots spreading the good word at 2FTS and BFTS.
