What if...
I have a little doubt regarding Class 1 Medical renovations. Suppose if, in the future when you fly for an airline and when you have to do your Class 1 Medical renovation something on the other turns wrong, let's say your vision gets worse and goes off the limits; i.e. according to JAR FCL 3 it must be between +5 / -8 with 3.0 dioptres of astigmatism.
My question is what exactly would happen? Would they make an allowance as you're already performing activities related to your licence, would they confiscate the medical certificate and you lose your licence or what would happen?
Thanks.
P.S. Vision deterioration is only an example; perhaps someone would, let's say, have a BP above the limit.
