Predictive validities of several clinical color vision tests for aviation signal light gun performance.

Validity of clinical color vision tests for air traffic control.

BACKGROUND An experiment on the relationship between aeromedical color vision screening test performance and performance on color-dependent tasks of Air Traffic Control Specialists (ATCS) was replicated to expand the database supporting the job-related validity of 13 FAA-accepted screening tests. METHODS The original experiment (10) (n = 108), and the replication (n = 136) involved a total of...

Predictive Validity of the Aviation Lights Test for Testing Pilots With Color Vision Deficiencies

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...

The ability of color defectives to judge signal lights at sea.

Measures were made of the ability of color-defective men to judge correctly the colors of navigation lights (red, green, or white) presented to them at night under realistic sea conditions. Eighty-one color-defective men were employed; they were categorized as to type and degree of defect using a battery of five color-vision tests. While the average performance of the color-defective men was co...

Validity of the Holmes–Wright lantern as a color vision test for the rail industry

A simulated field test was designed to determine whether the Holmes-Wright A lantern (HWA) is a valid color vision test for the rail industry. The simulation replicated viewing rail signal lights at 0.8 km distance under daylight conditions. Using the worst-normal as the maximum number of allowable errors on the simulation, 94% of the color-defectives failed both tests on the first trial and 92...
