Remember when I post these questions here I am not really in the loop with todays modern advanced training methods, simply because I no longer teach ab-initio flight training.
As to the CAA, I would be very surprised if they would be against using two stage amber for training as I can think of no reason they would.
Quite frankly it is my opinion that flight training is all ass backwards anyhow.....how can you have a high standard of training when the bulk of the trainers just learned to fly themselves and the industry pay reflects this.
You generally get what you pay for.
I know I'm going to get the standard argument about how these instructors are trained to a high standard and all those feel good things, but the fact remains there has to be a reason these highly trained instructors are working for slave wages.
There that ought to really get me flamed...
