For all you North American (NA) types (me included) this isn't like the US. You are continually graded from your first sim session in training through every sim and line check you will ever accomplish. Rating is 1-5. 1 you suck to 5 you are a CX dream!! Evaluations are brutally honest and aren't the "train to proficiency" you are used to in the US.
You apply for Command and are graded A-D by a Command evaluation group looking at your past training record. A your ready for Command training, B you need more work to D you'll probably never make it. Unless your A rated you don't get the opportunity for Command training/upgrade.
Quite frankly, Cathay Commanders (even the early 30's types) make your average and above average US Captain look weak and then some! Be ready for it if you want to come here.
