JB007,
BEagle will have all the info, but if I remember correctly the medical _proposals_ are:
(a) normal driving licence = solo flying (no passengers) or
(b) Class 2 driving licence equivalent medical = flying with up to 3 passengers.
So if your friend has kept his driving licence, some flying should be possible - if the proposals are carried through into legislation.
(Flying snapper - hear! hear! on the flying for fun. Not all of us want to give up good jobs for the airline treadmill, we just want to fly - safely. NPPL + IMC gets my vote)
