Interstingly, despite the UK CAA claims that their CAD Test would be the new standard for all Colour Vision testing under EASA, this is the Acceptable Means of Compliance straight off the EASA website. This is EU LAW!!
No mention of the CAD Test as an acceptable means of passing CVD tests.
Anyone heard anything about this?

AMC1 MED B.075 Colour vision
(a) At revalidation, colour vision should be tested on clinical indication.
(b) The Ishihara test (24 plate version) is considered passed if the first 15 plates, presented in a random order, are identified without error.
(c) Those failing the Ishihara test should be examined either by:
(1) 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
(2) lantern testing with a Spectrolux, Beynes or Holmes-Wright lantern. This test is considered passed if the applicant passes without error a test with accepted lanterns.
