Validity of clinical color vision tests for air traffic control.

Practical color vision tests for air traffic control applicants: en route center and terminal facilities.

BACKGROUND Two practical color vision tests were developed and validated for use in screening Air Traffic Control Specialist (ATCS) applicants for work at en route center or terminal facilities. The development of the tests involved careful reproduction/simulation of color-coded materials from the most demanding, safety-critical color task performed in each type of facility. METHODS The tests...

Reexamination of Color Vision Standards, Part I: Status of Color Use in ATC Displays and Demography of Color-Deficit Controllers

This report describes the status of color use in current air traffic control (ATC) displays. It represents the first step in our effort to reexamine the color vision standards for air traffic controllers. The current job-related color vision tests used by the FAA are based on an analysis of ATC tasks conducted in the 1980s. Over the past decade, many color displays have been introduced while th...

A Historical Review of Color Vision Standards for Air Traffic Control Specialists at Automated Flight Service Stations

This report chronicles several experiments the Civil Aerospace Medical Institute has conducted to assess the effects that advances in technology have had on automated flight service station air traffic control specialists color identification tasks and the ensuing revisions to the color vision standard and verification testing.

Aniseikonia Tests: The Role of Viewing Mode, Response Bias, and Size-Color Illusions.

PURPOSE To identify the factors responsible for the poor validity of the most common aniseikonia tests, which involve size comparisons of red-green stimuli presented haploscopically. METHODS Aniseikonia was induced by afocal size lenses placed before one eye. Observers compared the sizes of semicircles presented haploscopically via color filters. The main factor under study was viewing mode (...
