I agree those salaries are not unreasonable - in fact, they should be even higher in my opinion. What I haven't figured out is how to get the market to spport that. I already get complaints (although not too many) that the $50/hour rate we charge for instruction is high because freelancers (with no overhead, insurance ((liability, worker's comp, unemployement)), business license, etc.) charge less.
I think this has been a stumbling block in the flight trainig industry for many years. I'm fully aware there is a small market that will pay very well for high quality instruction, but it is quite limited.
