Rasco,

If you pass the Anomaloscope within the stated parameters then that is accepted as a pass under JARs and no other tests are required.

If you have met the pass criteria below for Nagel's Anomaloscope then you have been stiffed my friend and you need to get on to the authority asap!!

JAR–FCL 3.345 Colour perception

(See Appendix 14 to Subpart C)

(a) Normal colour perception is defined as the ability to pass Ishihara’s test or to pass Nagel’s anomaloscope as a normal trichromate (see
paragraph 1 Appendix 14 to Subpart C).



Appendix 14 to Subparts B and C

Colour perception
(See JAR–FCL 3.225 and 3.345)

1 The Ishihara test (24 plate version) is to be considered passed if the first 15 plates are identified without error, without uncertainty or hesitation (less than 3 seconds per plate). These plates shall be presented randomly. For lighting conditions see the JAA Manual of Civil Aviation Medicine.

2 Those failing the Ishihara test shall be examined either by:

(a) Anomaloscopy (Nagel or equivalent). This test is considered passed if the colour match is trichromatic and the matching range is 4 scale units or less, or by


(b) Lantern testing. This test is considered passed if the applicant passes without error a test with lanterns acceptable to the AMS such as Holmes Wright, Beynes, or Spectrolux.

Hope this helps and good luck
