Yaar indestructible,
There are just as many (or perhaps more) Americans advising in the UAE as Pakistanis. If Pakistanis were flying the blk-60s, the Americans would have brought this up and secondly we would have known about it more openly.
Familiarization flights on a blk-60 is one thing, flying them regularly to maintain hours on the platform is an entirely different thing. If I am not mistaken, we have done the latter on the Mirage 2000s but not on the blk-60s. The UAEAF has enough local pilots who do the flying on these aircraft. They have been very generous in inviting PAF for bi-lateral and multi-lateral trainings for the past few years in which we have interacted closely with the blk-60s and that is the extent of our familiarization. Once we have blk-52 inducted and have built a pool of pilots who are trained on it, then there would be a possibility that if UAEAF ever wanted to (I do not see any specific reasons) have PAF fly their blk-60s, we would be able to do so quickly.
PAF pilots have never flown Mirage 2000s of UAEAF, there is only one pilot in Qatar AF, Mehboob Khalid, he's flown it. Otherwise the only Mirages PAF flew in UAE were all III/Vs.
