Good points all around.
The point has been made that you would get better instructors if the pay was better, to which I agree to a point, but there will always be junior instructors with limited experience.
What is needed is for the senior instructors to take a more hands on approach in mentoring these juniors. It is not good enough to think that mentoring and developing junior instructors is the responsibility of only the CFI’s.
Unfortunately, as with most things in GA, the senior instructors don’t get paid enough to spend any extra time developing their junior colleagues.
I think that if we believe that the general standard of flying training is not good enough, then the only people that can change it is the instructors currently working within the industry. If we all strive to lift our own standards of airmanship, and do our best to pass this on to our students and our junior colleagues, then and only then will the industry improve.
