Got some bad news for you guys!!
You can not at present fly microlights under a JAA PPL(A), I fell into this trap myself, and have logged many hours in my 3 Axis machine, only to find out last week that the JAA PPL(A) is not enough for flying Micro's.
The JAA PPL(A) is a licence to fly quote "Single Piston Engine, Landplane" a-ha I thought, thats a Micro,......oh no, not according to Mr JAA.
Anyway Mr Ron Jenkins of the CAA, is getting the legal Dept. on the case, so as to reverse the situation. But at present to be able to legally fly Micro's on a JAA PPL(A) you will need to pass a GFT, and add this to your licence, the same as me!!
I suggest you call the CAA, and ask to speak to Ron (Mr Flight Crew Licencing himself), he's a good guy, and full of helpful information, besides that he's a pilot himself, and so I've heard a bloody good one, not at all your usual CAA suit.
