I'm in agreement with Bose, with some reservations! Those been that even high hours PPL instructors WILL take some time to settle into the job , just the same as the CPL/IR FIC guys do. To be a top class instructor will always take time and experience, it just so happens that PPL instruction is the bottom of the pile so the less experienced instructors will be found in these jobs, always has been always will be.
Now if you want to encourage highly experienced aviators away from the TRI positions, meaning those with a wealth of experience in aviation terms, someone is going to have to foot the bill, experience dosen't come cheap.
