Hmm, if you can go back in time and learn at a good cpl school at least 30 years ago...
5 Hours flight time to learn how to fly a relatively small single engine aircraft... Wonder how long a Navajo endorsement is now?
They certainly should add a training component about operating in and around turbulent conditions, that might actually be useful.
