One of the chief problems faced by GA flying schools is the appalling attitude of the many of the staff to prospective students.
Recently I visited a number of schools nearby, looking at getting into the air. I left a number of the GA schools thinking "I won't go there again", my wife had quite a bit to say on the subject. I finished up going to an AUF school several hours away and my wife will be going there for the full course shortly. As a generalisation I would say that the AUF instructors have far more experience than GA ones especially the instructors she would have.
The chief offenders appear to have no interest in the students other than to get more hours. GAPA appears to have the attitude "The money belongs to us"
