【 摘 要 】

To save energy, the FAA is planning to convert from incandescent lights to light-emitting diodes (LEDs) in precision approach path indicator (PAPI) systems. Preliminary work on the usability of LEDs by color vision-waivered pilots (Bullough, Skinner, & Milburn, 2012) indicated that red weak (protan) individuals made a few errors identifying red. Hence, this follow-up study explored whether clustering LEDs of different chromaticities of the same hue would aid users with color vision deficiencies (CVD).
