Color vision assessment by Farnsworth lantern: results using alternative pass-fail criteria.
Cole BL, Lian KY, Lakkis C. Cole BL, et al. Aviat Space Environ Med. 2008 May;79(5):509-13. doi: 10.3357/asem.2237.2008. Aviat Space Environ Med. 2008. PMID: 18500048 Clinical Trial.
Its efficacy was questioned following a crash in July 2002 because the DCV pilot confused the red and white approach path signals, despite having passed the Farnsworth test. The Farnsworth lights are larger and brighter than many aviation signals and it has a …
