Hi TedstrikerB777,

The medical center at Crawley only do Ishihara Plates and the CAD test. For the other types of colour vision testing, you have to do the at the City University London in Finsbury, London. A new web-based colour vision test | City University London

They start your assessment with the Ishihara Plates, then do the American version, then onto the Lantern and the rest of the older style tests then ending with the CAD. It's a lot cheaper as they only ask for a 60.00 fee whereas the CAA charge 125.00. You get a full set of certificates detailing your scores for each test that the CAA accept. If you pass any of the test mentioned on the CAA website, then you'll get an unrestricted medical. If you take these certificates with you to the Middle East and let the AMEs out there see, I can't see why they'd put you through further testing?

Best of luck!

Radio Failure

Here's something to ponder on. Last Sunday afternoon I was out in a C152. Whilst returning to airport my radios completely died on me. Tried the master re-set and resetting the circuit breaker. No joy. Luckily I keep the watchman number stored in my phone just in case. I got through and explained what had happened, they knew at the tower my radios were obviously faulty. He told me to keep circling and eventually follow as SAS CRJ on to final and after he'd landed to look out for the light signals.

Now here's where it gets interesting! I didn't inform the controller that I have a VCL on my medical due to "colour deficiency". I decided to take the gamble and see for myself. So first I noticed the steady red, then as soon as the CRJ taxied off the runway it went to steady green. I could see these lights clearly. It really wasn't testing at all.

Is it worth speaking to someone at the CAA about this little event? Or am I better off just speaking to a brick wall?
I'm even more frustrated now than I have been over the past two years. But something's telling me it's not worth it.

Any thoughts or comments would be good.

Cheers guys.

Hi all,

Anybody knows what's the Chinese medical's take on color deficiency?
I did use pprune search & google search but very old threads came up with very little info.
I've found one doc stating Korean automatically disqualifies if you are color defective.
We all know that Chinese medicals are very difficult to pass, I'm just wondering if there are any color defective pilots flying out there?

Cheers

the CAA have a vested interest in using and selling the CAD so I strongly believe the ladder would apply from your question.
The only way to solve this is to support CVDPA and join the fight on these guys..

shortfinals91, how did you get on?

I fail the Ishihara test badly, but feel I may fare much better at the lantern test. I'd like to have a shot before going anywhere near an application process so will look into London City.

I had to reschedule in the end, I'm looking to go in October now. I'll most certainly post an update once I've attended London City.

@2close and other UK CAA licensed CVD pilots

Hello,

I have read parts of this thread and the earlier #3. I appreciate the difficulties posed by a potential legal challenge in the UK/EASA-land. To start with, could we please COUNT OURSELVES and then assess what we can afford as a group?

I am a member of CVDPA but think we need to know how strong in numbers we are on our own.

Hi hegemon88,

This has been examined as a group.

The initial meeting with the barrister to look at the merits of the case cost 2,500 (and the solicitor did not charge for his time).

It was concluded that there were good grounds for judicial review and even merit in legal action under existing disability discrimination and sexual discrimination legislation, possibly even a route under genetic discrimination although this was clinging at straws.

The bottom line was that the barrister estimated high court costs at being at least 75,000, more likely closer to 100,000, a significant amount of which would have to be put up front, and this does not take into account a protracted case, contested by the CAA.

Of course, this was pre-EASA and no longer applies as the CAA simply claims that EASA is in the driving seat and that any action would need to be taken in the European Courts. Rack up the costs even more.

And going back to the original investigation into a legal action, we were left with no doubt whatsoever by a certain senior person at the CAA that "any action will be vigorously contested and we've got a lot more money and time than you......so bring it on" (I paraphrase!).

My advice....bin it....don't waste your time and money, use it for something more productive and more fun (I can give you the names of some decent bars in Thailand and Cambodia!). By the time you've spent 15 years and 10,000 of your own cash fighting and maybe winning the case followed by 100,000 + of your own cash getting your ME CPL IR/MCC/JOC/TR you'll be replaced by a ground based 'drone' pilot as the next (phablet) generation of passengers embrace pilotless passenger aircraft and the bean counters figure out how much they're saving by sacking all the flight crew!

Wow, I thought I'd stopped being cynical!!!!

Hello all,

Just though I would post this because I found it interesting but over the last week or so I have view the online CAD test video and while I understand it is not like the real test I found something quite interesting, i seem to always loss the square for about 1 second or 1 pass but on different days it is at different times, either at what appears to be the lightest shade of green, before it turns bluey green OR at the lightest shade of red - why would this be and what does it say for the test if my results were to change like this?


Also I will likely be going for the cad test soon, here in Australia (I will first be doing the Farnsworth but feel I may fail because I often have trouble naming the colour of lights despite being able to tell them apart)

what are my likelihood of success given I loss the square for about one second in the example and I scored 16/24 on the Ishihara.

Going for a CAD test... I'm trying to learn a bit about it. The more I know, the more relaxed I will be on the day is my logic.

I have seen the short YouTube clip, but how does the real test compare? Is it just the same but longer, and how do you follow the square? Using a pointer or something I imagine?

Thank you for any info you can share!

It's nothing like the real test but I'm sure you're well aware of this since you had the test in November.

Well here goes an appeal. I'm going to write to the CAA once I have my IMC ticket added to my license. Haven't tried an appeal yet and I've got nothing to lose! I was down at the city Uni and did the PAPI test and passed. Even though it's not "an acceptable means of compliance" it's still evidence in my favour. In my letter I'm also going to stress the fact that when I've had lessons at night (IMC training) I've correctly identified colours and have landed safely using the PAPI system! Even my instructor is pissed off with the system in place right now. So what the hell, as my AME said, "nothing ventured, nothing gained!"

I'll keep everyone posted with what the outcome is. Fingers crossed...

Color Deficiency

There is a company in Baltimore, Maryland (Colormax) that advertises it can allow a person to pass any color deficiency test that is mandated by the FAA and Transport Canada. They do not specifically refer to the FAA or TC but refer to the three (3) tests that these organizations use. It is apparently done through (after a through examination) with prescription contact lenses or eye glasses. If this is a successful procedure, I suggest that it would not be any different then correcting a pilots vision to an acceptable level through the use of contact lenses and/or eye glasses as is done now. Is anyone out there familiar with this procedure or perhaps has used it?

Corrective optics for myopia (short sight) return the vision to a fully correct state.

However if you have red-green deficient colour vision then this relates to the physiology of the retina and cannot be truly corrected with optics.

One suspects that the optics being offered enhance the light/dark contrast perception of the colours on the test charts, allowing the hidden patterns to be more visible to the colour defective eye.

As it is not clear that that would help you distinguish (for example) an isolated red navigation light from a green one in any real situation, where there is no contrast comparison to help you, it is doubtful that this is a valid corrective technique.

Hi

Please can you clarify something for me? Is it still CAA colour vision guidance that has to be met for a class 1 medical, or is it EASA?

If you fail the ishira plates test (which i will) you then go on to be tested by CAD. if you get a low enough threshold that is then the definitive test, and no further colour vision testing will be done for the class 1. Is that correct?

Hey Chris,

Yes, that is correct. Passing the CAD test will give you an unrestricted class 1. As far as I am aware, you would then no longer need to do any further colour vision testing. It's still only the UK CAA that has approved the CAD test.

Just so you know, the CAD test is pretty hard and it is significantly more difficult than the YouTube video shows. I thought I'd breeze through it and I was pretty dejected when I found out i'd failed (Deutan 8.28 at the CAA, resat at City Uni- 6.6 average!). I found my score improved when I got into a rhythm with it and tried to 'zone-out' a little.

Best of luck!

Hi everybody. I have also problem with my color vision, however I am just at the beginning to get my medical certificate. I'd like to get Medical Class II without restriction if possible - I live in EU. I have already failed Ishihara and Fletcher-Evans CAM Lantern. I wanted to be tested unofficially, however the doc seemed not to agree.
- Is there any register where my failed attempt is recorded which is shared by all countries in EU?
- I would also like to check if the record is there because now I don't know what to say the next doctor. Was I already tested or not?
- Let's assume the failed attempt is recorded, does it mean from now on passing Ishihara plates would not help cause I already failed it and therefore only FALANT is the option?

Thanks!
