It's nice to see a few sensible people giving input. I too gave my opinion based on a hard-earned and long aviation career. At the end of the day it is so: those that are b!tching and moaning will learn to tow the line or fall by the wayside.
As one who holds Instructor and Examiner status, I too believe that instructors are individuals who tend to go that bit further. My aviation career began in the charter industry but that wasn't enough. In fact, it never has been enough. There is always something new... Roll on graduation!
