Ian,
Thanks for the info. I am glad that OAA can oblige with the training.
What is most encouraging for others is the fact that the CAA are open and fair with properly evidenced medical issues.
The decision with your case seems to be a common sense one (not always the case with many organisations) and is also useful information for others. Likewise, there is merit in continuing your efforts for an unrestricted medical as all of the applications I filled in prior to my ailment being found asked if my medical was unrestricted or had ever been restricted. Obviously it is not the case with every airline, but having said that an unrestricted class 1 is also no guarantee of a payback on your investment and OML may still be more than adequate.
Good luck with your efforts and many thanks for your post, I am sure many will benefit from your experiences.
Regards,
VFR
