I feel the same 2close. The FAA system works. 95% pass the light signal test and there are 16,500 CVD pilots in US over 2000 of those ATP holders. Only one accedent that mentioned colour vision (Talahasse) and then fatigue was probably the major cause. (2 other colour normal crew!!).
I have unrestricted FAA and it Pi
me off as I'm English and cannot work in USA and my home and family are in England.
More to come soon - I'm looking into my own chalenge.
