Thanks very much everyone! Unfortunately I did talk to the Chief Clerk and all I got was "uhhhh, yes I'll try and find out for you Sir." Followed a few weeks later by "Oh, sorry Sir, we've all been very busy Sir." Shortly followed by me enquiring sotto voce whether that was a contradiction in terms.
In this case I would hope that the PMA bit wasn't a problem as I've been the one talking the docs into letting me do the fitness test, albeit the peddaling one, to prove that I'm not a biff. Got above average on everything last year, even with the spare tyre!
Thanks again all
