Cumulunimbus -
unfortunately, to convert a non-JAA license to JAA, one must pass ALL 14 exams. To validate a license (1-yr validation), it is only necessary to demonstrate knowledge of JARs.
There are some countries (see Italy) which will validate a professional license in order to allow one to obtain a full JAA license, but, at the end, one must still pass the 14 exams.
BTW, very cool name. I guess friends can call you CB?
PEACE
