POLL - Reliability of the Online Demo
Title says everything.
Of course I know that color temperature, etc. may vary between monitors,
but I think it could be interesting anyway.
ANYONE WHO DID THE CAD PLEASE CLICK HERE

Unfortunately you have to scroll down
Thanks a lot to everyone who supports this,
best regards

Additionally, individuals have limited resources with which to fight whereas the CAA would have absolutely no hesitation in spending, if necessary, millions of pounds in tax-payers money to defend legally and morally indefensible positions whislt at the same time letting the Appellant know in clear terms that should they win their case they will be claiming ALL of their costs from the Appellant. That places any Appellant in an impossible situation of knowing they stand a very high chance of winning a case but at the same time knowing they will lose everything, i.e. the literal shirt off their back, should they lose.
It is nothing short of corporate bullying, for which the CAA is renowned throughout the aviation industry.
I have been told from within the CAA that they are extremely wary of being taken to Court on this issue but without the funding required the fact is that they can laugh from the sidelines.
All that is needed is the support of someone with plenty of political clout and plenty of money to fight the cause then the smug smile can be wiped off their arrogant faces.
I'm up for taking them on in a drinking contest or in the boxing ring - winner takes all!! Anyone else in?

Colour blindness
I'm asking this for a friend as he doesnt have an account:
He can see the plates and the numbers at the top of this page
Ishihara Test for Color Blindness
but at the bottom there is one (tbh the writer cant see it aswell,)
it should be a 5 but i can sometimes see both depending on the angle
will this affect a class 1 ???

Don't use the internet to diagnose colour blindness. The Ishihara test plates have strict lighting requirements in order to accurately assess colour blindness.
If you're borderline, it could make all the difference.

As redsnail says - don't try using the internet to diagnose colour blindness. The version of the image you are looking at may have been unwittingly altered (e.g. during jpeg compression) and your computer/monitor may not be able to render the colours properly, so your eye sight may be fine but you could still struggle a little to see the image.
Looking at it myself I struggle to see the 5 (I can make it out knowing that it is there, but can't say I'd definitely be able to otherwise) - and I've been tested for colour blindess without issue twice within the last month (once by an optrician, once by occupational health at NATS) - so I wouldn't worry about it.
I'd also add that I've never in my life been presented an image like that one in an Ishihara test. The other images on that page are much more like what you should expect.

I have a green colour deficiency.
I did the CAD test at City Uni in April 2009 and failed, 8.82 /rg, 1.13 /yb.
A few weeks ago I did the CAD test at Gatwick. First attempt I got 6.54 /rg, which is 0.54 above being colour safe. Because I was boderline, I was required to do the test 3 more times to get an average. Unfortunately the lowest I got was 6.44 /rg.
So annoying!

Well, don't feel too bad about not passing the color tests at your initial medical!
It's worse when they fail you for it AFTER you spent all your money and effort in training!
My situation:
I failed the Ishihara test at my initial class 1 medical. I then was given the anomaloscope. The result was Deuteranomaly 5.25 and 2.15 for each eye. This was within limits at the time so I got the class 1.
Now I'm in Indonesia trying to get a medical validation for my first job. I fail the Ishihara test again. I've not been given any other specific colorvision test afterwards. They fail my medical. It turns out that they do not allow any form of color deficiency.
When I went for a 2nd opinion, the specialist tested me extensively including Ishihara and a lot of other tests, but no specific 2nd colorvision test. Because I did pass the medical in Europe, have a license and a rating, he tells me that I'm fit to fly.
Unfortunately, the DGCA of Indonesia did not concur and they still failed my medical.
Basically this means that I'm out of a job, on the other side of the globe, with a good amount of debt and no savings. (I've given all to get this job in the first place.)
Not getting the medical is bad, but maybe I would've been in a better position if I hadn't gotten it in the first place?

So the discussion finally admits that different computer monitors, especially older ones, can affect the hue, saturation and contrast definition of displayed colours and should not be used for testing purposes......now, where were we on that CAD Test?????
As for Ishihara, I can see two numbers on several plates and it varies greatly with the lighting conditions as to whch is the clearer. If I am tested in daylight conditions as per the manufacturer's instructions then I see the correct stated number but if I am tested using a lamp, especially an old defunct lamp with a worn out bulb then I see the wrong number.
Interesting?

CAD Test
Hi all,
I have been doing some research on the web and I can not find the answers to these three questions!
Is the CAD test available?
Where can I do a CAD Test?
How much does it cost?
I've wanted to become an airline pilot all of my life and now with the prospect of this new test I might be a bit hopeful. I read that 35% more prespective pilots would pass the test! I could be in that 35%!!
Please help,
Thanks,
Ben.

Benjamin,
You can do the CAD test at CAA house for the bargain sum of £120.
It is a professionally run test and you will have the opportunity to familiarise yourself with the setup before commencing the test.
If you score between 4 and 7 on either of the axes (read more about these in other posts) you will then be given the chance over 3 runs of the test to obtain an average that is lower than 6 - this is the pass mark.
I have been involved in the research process since day 1 and have sat the CAD many times. I found the testing at CAA house the most unpleasant of these experiences for reasons that I am not quite sure.
If you pass you will be given a UK issued Class 1 medical - I await more informed opinion as to what the rest of JAA and EASA think about this.

cad test
hi,
Just saw the post, I will be to the point on... it does not matter is you pass or fail the Ishihara test... it does not matter if you pass or fail the Lantern tests... cause these tests do not prove anything.....
the cad test is another test that you can quite easliy pass and fail as well, and no one can tell you if you will be in the 35% that pass. You could pass the test, as much as you could fail it.
seriously the whole colour vision thing is allot of ****... we can see primary red.green.white, colour used at night in aviation, the tests do not factor this, ishihara is shades of colour, we dont have runways that have a shades of red or green, pure colour dont we.. the cad test does not prove anything as not practicle.
Aviation is not a very pleasent place at the moment...
the rulemakers are not thinking practicle and never will...

KC
hi
I have a KC, I had an FAA class I without any issue. Now normally the applicants with kC can have an assesment if the visual requierements are met, and a regular follow up is needed. If you just have been diagnosted with KC, make sure to do a regular check, and if it's progressing try to use lenses or whatever to stop it, because when it begins to develop, it's very quick (I passed from 10/10 to 6/10 in 2 years only, or less)
Good luck

Hi,
Just found it: http://www.city.ac.uk/avrc/avrc/colourtest.mpg
If you have done the actual test please could you give me a brief description about what happened on the day? How were the test conditions ect.
Many thanks,

I have done the CAD at both Citi Uni and the CAA, and be prepared for a less than pleasant experience.
The test will take between 12 and 15 minuets. You sit with your chin on a rest staring at the center of a CRT with a box in your hand that has 4 buttons. Top Left, Top Right, Bottom Left, Bottom Right, you have to press the button to the corner where you think the box is going. The test is taken in subdued lighting conditions.
I personally left the test with my eyes streaming and feeling totally drained. Just try playing that demo for 15 minuets with your head held in a single position, the lights off and the pressure of the rest of your life depending on your results!!
Myself I failed, but there I have failed all the CAA tests and the anomalascope at Citi. In fact the only test I have passed is the PRACTICAL FAA Tower Signal Test and I have my LOE and an unrestricted FAA medical. Great because I am a UK citizen with no right to work in the US.
The CAD is just another useless piece of junk that continues the academic wet dream of the CAA - and gives them a lot of brownie points along the way, and perhaps riches as well!! - ohhhh did I say that.
All the best with the test - I hope you DO pass. Just do what you can before to go in feeling your best, and on top of the world. If you are doing it as part of your C1 then ask to have the CAD as your first test, if you have it later the other tests will have worn you down a bit.
Hope this helps.

cad
what do you say we do something about this?
I already tried in the past and gathered a group of people.. But we need to do some action. It depends on us and we have the aid of globalization, knowing what's happening in Australia and in the USA.
PM me whoever is interested in trying to change their unfair fortune...
