Iver,
It's no different than an SO position in QR on the 320 or any other fleet.
The general ground courses everyone does. Type rating, and line training 86-120 sectors.
I could be a little off with the sectors but is within that range.
After that he/she is a cleared F/O.
Not to mention that he won't even have a cover pilot the whole 120 sectors.
Just him/her and a Captain. And he/she logs the hours.
Perfect opportunity, which exists all over the middle east, except QR allow non nationals to be part of the program(limited number).
