Apolgies for the thread drift.
Shunter, I spoke to the CAA a fortnight or so ago. They said I could do the CPL by taking the mandatory night flying section during the day. Fair enough.
However, their stance on the IR was that I couldn't do it because I couldn't get the night rating. I suggested what you just said, attaining the night qualification dual, but they said that they would not put a rating on my licence that I'm medically unable to exercise.
That at least was their scripted response. My request is now with their specialist FCL person, who's away on leave. Who know's, maybe I'll get an answer this month!
Dublin, you're correct and it is I believe 1 in 10 males. I know people who've got round the CAA, so there is a precedent of some sort for me.
Again, thanks for your input guys.
