The CJ? The irony is there most people venture into something like a jet well after many hours in smaller GA aircraft learning the basics of flight. By the time you ‘move up’ to the CJ, the vast majority of the flight is management of automated systems. You’re not really trimming out a CJ at 41000’, Things are happening way too fast. Maintaining honest alt/airspeed in a C152 is plenty challenge enough to get started. Even the circuit lesson for the 152 isn’t the easiest for a seasoned pilot to nail it.
