Well the head of your DGCA sounds like a real brain surgeon.
The reason you need expat pilots and will always need them is twofold.
Firstly it's a numbers game; you won't be able to train enough pilots to crew the number of aircraft on order; certainly not to sit in the LHS. If you do upgrade inexperienced FOs you will have aircraft crashes. That brings us to the second reason (same as Korean) which is experience and safety.
You need us; you can't get around it but we will make you pay through the nose for it. We will push the pay rates up (simple supply and demand), and force you to base us off-shore. Thanks chaps!
