FOK - spot on.
I know many experienced PPL instructors who would love to take it to the next level and teach commercial flying as an alternative career to the arilines.
This CTC scheme could have been a great opportunity but they have shot themselves in the foot by insisting on 150hrs IFR time.
How is your typical PPL instructor going to gain theses hours? By getting in with the airlines or some kind of air taxi work, in which case he's highly unlikely to step back into instructing.
Would be interesting to see how many serious applicants they get.
