EASA Opinion 09/2016

Hi guys, first message here !

I just saw this :

https://www.easa.europa.eu/document-...easa-downloads

the draft annex is available here :

https://www.easa.europa.eu/system/fi...Commiss....pdf

We can read in it :

If a night rating is added to a PPL or LAPL, the licence holder shall be colour safe.
and few pages after :

MED.B.075
Colour vision
(a)
Applicants shall be required to demonstrate the ability to readily perceive the colours that are necessary for the safe exercise of the privileges of the
applicable licence(s).

(b)
Examination and assessment
(1)
Applicants shall pass the Ishihara test for the initial issue of a medical certificate.
(2)
Class 1 medical certificates:
(i)
Notwithstanding (b)(1), applicants for a class 1 medical certificate who do not pass the Ishihara test shall be referred to the licensing authority and shall undergo further colour perception testing to establish whether they are colour safe.
(ii)
Applicants for a class 1 medical certificate shall be normal trichromats or shall be colour safe.
(iii)
Applicants who fail further colour perception testing shall be assessed as unfit.
(3)
Class 2 medical certificates:
(i)
Notwithstanding (b)(1), applicants for a class 2 medical certificate who do not
pass the Ishihara test shall undergo further colour perception testing to establish whether they are colour safe.
(ii)
Applicants who do
not have satisfactory perception of colours shall be limited to
exercising the privileges of the applicable licence(s) in daytime only
Here you can find the :

Draft acceptable means of compliance (AMC) and guidance material (GM) to Part-MED

https://www.easa.europa.eu/system/fi...%20only%29.pdf


This limitation allows holders of a class 2 or LAPL medical certificate with varying degrees of colour deficiency, to exercise the privileges of their licence by daytime only.
AMC1 MED.B.075
Colour vision
(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; or by
(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.
As you can see, CAD test has been included as said in the Comment Response Document.

It's time to wait for the decision.

Sorry for my english, not perfectly fluent yet .
