(ii)Applicants shall be normal trichromats or shall be colour safe.

(iii)Applicants who fail further colour perception testing shall be assessed as unfit.

(3)For a class 2 medical certificate:

(a)At revalidation and renewal examinations, 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 if the anomalous quotient is acceptable; 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.

(3)Colour Assessment and Diagnosis (CAD) test. This test is considered passed if the threshold is less than 6 standard normal (SN) units for deutan deficiency, or less than 12 SN units for protan deficiency. A threshold greater than 2 SN units for tritan deficiency indicates an acquired cause which should be investigated.
