Ok, this might sound a bit odd, but in the current situation of political correctness, equality etc etc, If someone was just outside the class 1 eyesight reqirements, and could prove they could safly fly an aeroplane and complete all the required training, If the CAA then refused to issue a Class 1 medical would there be grounds for a discrimination charge against them, as it has been PROVEN by the succesful completion of training and flight tests that the person is competent and safe. I cannot see how they could fight this as it would be blatent discrimination
