If I'm writing on pprune it's only because I've reached my 900hrs/year
Cargo? Never heard. But if anything is worth doing, I'm sure AA will think about it.
We have our "own" clinic in Sharjah Airport. It's a standard UAE GCAA class 1 medical, straigh forward. There is only one exam (that I don't remember) that you can do in any hospital.
Every month we have new second officers MPL coming from Alpha Aviation, it's not an easy jump from cessna to Airbus, but they work and study hard.
Cheers!
