Thanks Cav.
the restriction is on the medical certificate not the license it self.
one of the CAA doctors said that it shouldn't be a problem because all airline operations are multi crew ops. however he said if for example something happens to the other crew member in flight i would not be qualified to fly that aeroplane on my own. so i am a bit lost here but when i go there next time i'll speak to one ofthe doctors and see what could be done about it. i hope it wouldn't be a problem.
once again thanks for the info. much appreciated.
