As an ATCO I have just been given a new form and been told that I need to go and have my colour vision tested(as part of my yearly medical). I did this...27 YEARS ago and after a look at Isihara...and seeing many plates with more than one answer(to my eyes) I was given the lantern test. To cut a long story short I got through BUT today on doing the Isihara again I had the same difficulties as in the long past. My question is....the CAA(UK) form now states Colour Vision SAFE/UNSAFE. My optician would not tick either box as she had had no guidance at the criteria required to make that assessment.
What would be a number of missed plates which would trigger an UNSAFE reading?
(I did 16 with 2 missed.)

Not particularly familiar with ATCO medicals, but I presume you'll need to head off down to Gatwick and do the lantern test again. You should only ever have to retake colour tests "on indication", for example if you've had a condition which might affect your colour vision (apparently there are some). Personally I would have refused to take the test, although that's not much use in hindsight.

Maybe in a few years there won't be a colour blind thread on this forum

The point was, that you should not be retested for colour vision unless you have had a condition which would indicate it necessary. Such conditions are extremely rare and forcing a test without such indications is outside the scope of the medical.

Shunter is absolutely correct in his statements and from what I read above it seems that you are able to go to your local optometrist to have your colour vision tested but that she would not sign to say that you are COLOUR SAFE . Go back to her and refer her to the Instruction Manual tucked away in the back of the Ishihara Plate book, in particular Page No. 7 (Analysis of the Results) where it clearly states that Plates 1 - 15 are used in the test and if 13 or more plates are read normally the colour vision is regarded as normal, i.e. no more than two errors.
Do not confuse the issue by involving the CAA, if this can be avoided as they will manipulate the results to their satisfaction.
BTW, if you do lose your medical as a result of this despicable action by the CAA, please feel free to consider legal action against them. The more law suits that land on the doorstep of CAA Legal, the better.

FAA Colour Vision and FAA CAD
Below is a good link to current FAA Color Vision requirements
https://aviationmedicine.com/article...e&articleID=31
I'm glad I have my Letter of Evidance
Below is a link to the FAA and the new CAD test. Most of it we have seen before in the CAA doc, but this gives an FAA slant

Enjoyed the FAA take on it...
No sh¡t Sherlock...
On another note; does anyone know if CAD scores recorded during the development study have been retained by the CAA? Would be curious to know what mine was.
1.2.3 Disability Discrimination
There are further considerations that justify the need
to establish safe, minimum requirements for color discrimination
(when appropriate) and to avoid the easier
alternative (from a regulatory viewpoint) of requiring
every applicant to have normal color vision. The recent
UK Disability Discrimination Act (2004) has, to a certain
extent, exposed weaknesses in the current standards
and procedures.

Shunter,
From what I can understand the AVRC at City University has retained the test results and will disclose them to you if requested.
I'm not sure they have released them to the CAA as to do so would be treading on very thin ice vis-a-vis data protection and medical confidentiality (not that that has ever bothered certain Departments who, as we all know, don't walk on water but hover above it, or so they believe!).

I got my CAD results from the CAA (taken at Aviation House) by a Subject Access Request. I compared with the graph City Uni had given me when I did it with them. The two are similar, but not exact.
The CAA graph had numeric units at the bottom, City did not. I sent copies to City and asked if they could give me numeric results, they came back much the same - still way out of a pass.
I would like to be able to take the CAD at somewhere else that is say a little more impartial - just out of interest. I guess I will be able to do that in a lot of the world soon!

CAD Test
Rahbani, the test is now in use with the CAA if that's what you are hoping to go for. It consists of a computer screen with a small black square in the middle about 5x5mm in size. A block of one colour will move from one corner to the other and you have to tell the examiner which direction the block went in to prove you can see the colour. To do this you are given a wireless handheld device with 4 buttons on. These buttons point to each corner.
Someone before mentioned that there is a button in the middle to show the sequence again but this is not true. If you cannot see the colour then just guess, there is a one in four chance you will get it right. The test even sometimes shows no colour at all but this is not an issue.
I failed previous CAA tests but passed my FAA Farnsworth Lantern and luckily just lately passed this CAA CAD test so now I have my unrestricted CAA Class 1 Medical.
Please let me know if you want any more help or information on this. Good luck.

Coverting ICAO Class 1 medical ( no restrictions)
I hold an FAA Class1 medical with no restrictions. Passed the Farnsworth lantern test.
It used to be, for conversion purposes, that you would be tested at Gatwick as a renewal and that did not include a colour vision test. They changed this about 2005/2006.
My question's are:
1. Has anyone attended another JAA state to convert their FAA Class 1 to a JAA Class 1 and not been colour tested? If so which state, AME and how long ago?
2. Has anyone attended Gatwick recently and had their Class1 conversion conducted as a renewal and issued? Without a colour vision test.
3. Has anyone been invited back to Gatwick recently because they were marginal to sit the new City Uni test. If so, how did you get on?
Thanks

I passed the CAD!
Hi guys,
Well, I've been living on grandfather rights on my class 2 and with a restricted class 1 for ten years. Anyway, took the CAD today and was convinced I'd stuffed it up but, with 4.33, I passed!
The bloke in the Aeromed centre (called mark) at the CAA was really super and set me at my ease, which is more than could be said for back in 1999 when I flunked the Holmes-Wright.
The test has changed a little from the prototype at City Uni (no chin rest and letterbox to look through) and you have to sit 1.4m (+/- .4m) from the monitor (hooked up to a lappy) on a comfy chair.
I'm going to write to the CAA and City to thank them for the time and money they've invested in this project as I can now, finally, realise my dream!
If you're like me and 'slight' (in my case 9/15 ishiharas incorrect!) in your CVD, then do splash the £120 and see if you can get through.
All the very best

I have sat the CAD at City and the CAA.
My results at City did NOT have a numeric value. I got my results from the CAA by doing a Subject Access Request. They requested a numeric value from Citi Uni!!
I then sent the graph I got from my City test to City Uni to ask for a numeric result and surprise surprise they come back very similar > 15 SNU so FAIL!!
Considering all I will be happy to take the test at an independent venue when available!!

Hi all, I heve a CPL and I have flown almost 3000 hrs including night, IR as FI and mayor airline. When I did my initial medical check I only had to read 5 o 6 plates, probably the nurse was tired and I passed. I had no notice about my problem and in the renewals usually I didnt have to do the Ishihara. But now I know that I can´t see all the plates, I fail some of them. So, in the first place, with my experience, I now that I can fly safely, when probably I could have been rejected in my first medical. And probably most of you can do it!. The rule is stupid.
Now my questions:
1-The CAD will be accepted or adopted by EASA?
2-The color test is not required in the new EASA anual check, is it required in the JAR-FCL in force now?
3-Does anyone know where they don´t do the color test in the annual check in Spain?
Thank you
