Minimum color vision requirements for professional flight crew. Part III, Recommendations for new color vision standards

"This report describes the findings of the third phase of the project sponsored by the United Kingdom Civil Aviation Authority on "Minimum Color Vision Requirements for Professional Flight Crew." This third part of the project, "Recommendations for New Color Vision Standards," involved collaboration and co-sponsorship by the Federal Aviation Administration. Minimum color vision requirements for professional flight crew have been established by assessing the level of color vision loss above which subjects with color deficiency no longer perform the most safety-critical, colorrelated tasks within the aviation environment with the same accuracy as normal trichromats. The new CAD (Color Assessment & Diagnosis) test provides accurate assessment of the applicant's color vision. The results of the test establish with high specificity whether the subject's red-green and yellow-blue color vision performance falls within the normal range and the class and severity of color vision loss in subjects with color deficiency. The results of the test also indicate whether the applicant's color vision meets the minimum requirements for safe performance that have emerged as necessary from this investigation. If the new, experiment-based, pass/fail color limits were adopted as minimum requirements for professional flight crew, 36% of deutan subjects and 30% of protan subjects would be classified as safe to fly. Given the higher prevalence of deutan deficiencies, these findings suggest that 35% of color deficient applicants would be classified as safe to fly."--Page i.
