I would like to know if there are any official reports pointing Color Vision Deficiency (CVD) as a major contributing cause of an air accident/incident. Not only related to flying but also maintenance or ATC for instace.
So far, I have only come across with FedEx flight 1478, in which a CVD F/O misjudged the PAPI lights. However, the report does not point how severe was the F/O's deficiency (all crew survived the accident). And more important is that the Captain and Flight Engineer (with normal color vision) could neither detect the wrong glidepath.
My final goal is to research the topic of color-blindness in aviation with real case instances and hopefully draw some conclusions about the actual impact of this disease in aviation for candidate's medical certification.
