FAA Class 1 to JAR Class 1
Hi
I just sent the CAA a similar enquiry concerning converting my ICAO CASA CPL (H) to a JAR CPL(H).
With regard to the Class 1 Medical if you have a current FAA Class 1 Medical and a valid CPL you only have to undertake an "extended renewal" at Gatwick and do not have to do the full initial half day medical with all those nasty flashing lights and heavy breathing.
Cheers
