I went to aviator college, did everything from PPL-CPL and CFI, CFII, MEI. I worked there as a flight instructor as well.
It is a very good school for the amount of money you pay.
But i need to tell you one thing though, and my belief is that this a problem with ALL school in ALL countries.
You as a father need to make sure your son is mature enough to go a school that charges by the hour for flight training.
If he goes in 100% he WILL do everything on minimums. Every student i had did theirs on minimums and all of them had first time passes.
But i have seen students come on mom and dads retirement founds and wasted everything, partying every night, running after skirts and then come on different forums complaining about the instructors not babysitting and feeding them with the spoon.
There is something you need to understand when it comes to instructors.
We do not get paid for ground school, we only get paid for flight time.
The Federal Aviation Regulations have sections that determine exactly what we need to teach and to what standards we need to teach it.
That is what he will get, no more no less. Your son will be responsible for getting there.
