FAA AME Color Test Reliability Study

This project will evaluate whether Federal Aviation Administration (FAA)-approved color vision screening methods produce consistent, reliable, and scientifically defensible aeromedical certification outcomes. Aviation Medical Examiners may use multiple approved tests, but applicants can potentially receive different results depending on the test, device, or testing location. The effects of equipment calibration, maintenance, and other sources of test variability are not sufficiently understood. The research will compare approved screening methods across devices and locations to determine their reproducibility and equivalence. It will assess how equipment calibration and device-specific variation influence test results and whether these differences materially affect medical certification decisions. The project will also identify actions needed to improve the reliability, consistency, and quality assurance of color vision screening. Preliminary findings are expected in fiscal year 2028, with final results required by June 2028. The FAA will use the evidence to determine whether changes are warranted to screening policy, approved testing methods, Aviation Medical Examiner guidance, training materials, equipment requirements, or quality assurance practices. The expected outcome is a stronger scientific foundation for color vision screening that supports consistent and equitable certification decisions while ensuring that pilots can safely perform aviation tasks requiring accurate color discrimination.
