Forget about Emirates Aviation Services , they charge around 400$ per hour for a 172/PA-28 and all you;ll get then is a GACA PPL which you'll find hard to convert to EASA . I suggest you either do it whenever you can while back in Europe or head out to the US and do it as an intensive 2 week course then convert to EASA when you have the flight time , which is 100 PIC if I recall .
