Hi Geardown 737,
Flatspot is correct on the procedure to convert your license into a UAE one. I just wanted to add the financial side to this.
Medical 1300, AED (400€)
License 1360 AED (420€)
Typical Aircraft+instructor 600 AED/ hr (190€)
So, GA is quite expensive here,
Nevertheless a great place.
Hope it helps,
V1GO
