NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Conduct research to determine the effectiveness of each of the current Federal Aviation Administration-approved color vision test protocols (including the color signal light test) at effectively screening out pilot applicants with color vision deficiencies that could impair their ability to perform color-related critical aviation tasks including (but not limited to) correct interpretation of glideslope information and in-cockpit displays that use color to convey information. The research should take into account the time typically available to perform each task, particularly under emergency conditions, and the potential effect of mild hypoxia (as might occur at typical cabin altitudes) on color vision deficiencies.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to study how well its approved color vision tests (including the color signal light test) identify pilot applicants whose color vision deficiencies might interfere with tasks like reading glideslope information or color-coded cockpit displays. The research should consider the time available for such tasks, especially during emergencies, and the possible effects of mild hypoxia at typical cabin altitudes on color vision deficiencies.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
