Where can I learn more about the CV designations and what tests are applied to a candidate to determine them?

This thread works too.

Colour Blindness
« Reply #51 on: September 22, 2017, 15:49:47 »
I have a slight colour blindness that does not affect me in everyday life. Can anybody talk more about the tests they use for this? I am able to pass the Farnsworth D-15 (arrange the colours/shades in the correct order) but I cannot pass the Ishihara Plates.

I am very interested in becoming a pilot but I understand it is a long, exhausting process. Don't want to waste my time just to get to the end and realize that I can't do it.

Thanks!

According to the medical standards for the CAF, pilots must reach the standard for "Colour Vision - 2", which is defined as:

CV2 – Abnormal Colour Vision (Minor defects) – CV Safe
Fail Colour plates
Pass Farnsworth D-15 Standard test

Thus, not being an expert, my impression is that you meet that standard.

You would not "get to the end and realize that I can't do it" (for this reason, at least), as you would have to be declared medically fit prior to being accepted as a Pilot applicant.

There are many threads here on this fine Site that discuss matters relevant to you and your application. I suggest that you begin exploring.

Hello guys,

Been a couple weeks i really look in this forum since i applied as a Pilot two months ago. Doing my CFAT next week. I have read everything on colorblindness but i dont understand the "lantern test can only be conducted as secondary test by aircrew applicants".

Before doing my official medical test with the CF i wanted to clarifiy this. I can't pass the ishihara color plates, at all. I pass every other color test easily, including the lantern test, so i'm technically not G/R deficient. If i am an aircrew applicant and take the secondary test (lanterns) and pass it, does that mean i can still be CV1 ? (i've read that its possible to fail the ishihara plates for other reason than colorblindness, even tho its really rare).

I heard CV2 can't do night missions and they are rarely accepted as pilots even if they meet the standards.

If you refer to this page:
http://www.forces.gc.ca/en/about-policies-standards-medical-occupations/cf-colour-vision-testing-instructions.page

you can see that the only way to be declared CV1 is to pass the colour plates. CV2 means you failed the plates but passed the Farnsworth. CV3 means you fail both.

Paragraph 4 of the General section further states: "Assessment of colour vision by either the Holmes-Wright or Farnsworth perception lanterns will only be conducted at CFEME Ophthalmology Dept for selected MOSIDs. The colour lanterns are no longer used as secondary tests for those who fail the colour plates, except for aircrew applicants."

Pilot is CV2.
