There are operators (instructors) in flying schools that think the more dual a student has the better he will be. For that reason they deliberately delay a students first solo for 15-30 hours or more because of perceived "safety".
In reality it is a blatant rip-off. There are new grade 3 instructors who either do not have the confidence to put their student for a CFI check for first solo or worse still want to squeeze a few more bucks out of the student dual and hang on to the poor bastard for as long as possible.
Well said,
Unfortunatly I was one of these kids back when I first started. I was one of the lucky ones that realised I was perpetually funding greedy old bastard owner/CFI's retirement and left for a better school. Others didn't and their careers were destroyed before they started.
