You can have every type rating in the world, 2 things you must also have is the type on the UAE register and a minimum 2 years signing experience on each type! No if or butts. The GCAA are considering allowing a type rated person without the min 2 yrs signing experience get an 'A" license.
This is only an option with your companies assistance and this being the middle east will take time how long? How long is a piece of string?
If you now have 330 and 345 as well you must have been working there no one gives a type rating and then a nnother one if they have not got some benefit of the first one.
Oh I miss the BCARS when you first had to get company approval then apply for type within regulatory body.
QA used to try and tear you a new one every time you went to see them.
Also if you wish to sit mod 10 you have to be sponsored in the UAE or so I thought?
