Hello,
I failed the ishihara test on my 2 JAR class, but as alternative test I has few grey triangles - in every cornel was colour light (red, green, orange etc..what is name of this test?). All my answers were correct so I passed. Have I chance to pass tests for 1 class?
Ive been reading this thread as i am soon to be moving to New Zraland and am going to be looking to hopfully geting my CPL but as im colour blind as ive been reading it may not be possible. Ive been playing around on the net and have come across a company in the USA who say that with corrective contact lenses or with glasses they can cure colour blindness, i was wondering wheather there are any restrictions on using these to gain a medical certificate on the understanding that these glasses/ contact lenses were worn when flying?
Chris.

Hi Piotrek,
That does not sound like any JAA alternative test I have heard of and think it may be a national test (Poland only) which would only apply to Class 2. It may be accepted by the Polish aviation authority for Class 1 but you would have to ask them.
I doubt the UK CAA would accept it if it is not one of the JAA approved types of test but so what, get your CPL in Poland. It is fully recognised as a JAA member state and the licence would be valid everywhere.
I would be very interested to hear more details of the test.

As far as i know Chris here in Australia and New Zeland you cannot use any form of corrective lense for colour vision.. Sorry ... This is not to say you cant hold a licence, though it would probably be restricted in some way..

And that is like saying that an asthmatic pilot cannot fly with his inhaler or a myopic pilot cannot fly with his glasses.
Whilst I freely admit that this needs looking at a bit closer (and I don't have the time right now) if the authorities cannot come up with a valid, scientific reason, based on absolute fact and not just the whims of the old boys club, then this would be highly discriminatory.
The authorities are skating on very thin ice vis-a-vis this issue of CVD and it is going to bite them in the backside very soon.
As i dont know how colour blind i am as regards to a medical certificate i think the only thing i can do is to go along and get tested and foind out for sure before i make any decisions about scraping the whole idea.

Chris,
I don't know if the same rules apply in New Zealand but in Australia you can hold a class 1 medical certificate with CVD and you can hold a CPL and fly commercially.
You may wish to check with the NZ authorities.
However, a note of caution, the current figures (and again I refer to Australia) are that there are 14,000 CPL holders not engaged in flying jobs so competition may be strong.
I thought I'd post a note following my visit to City Uni yesterday. When I got my medical (and failed Ishihara) in January, I subsequently went to Gatwick and failed both lanterns. They put my name forward for the City Uni research project, and after a few months wait I went down there.
First of all was good old Ishihara, a few different variations of, all of which I got some wrong. Second was a test based on the sample they have on their website where you follow the coloured square around the screen. Completely different to the website version though; it's designed to give a really accurate evaluation of where your colour deficiency is and to what extent you are affected. The conclusion of this, and I quote "Very mild dueteronomy (sp?) and your green cone wavelength recognition is left of centre, which will mean green/white differenciation is where you'll have trouble". Nice to finally get something other than "sorry sir, you've failed, now **** off".
After a couple more tests including the anomoloscope we moved onto their really useful test, the PAPI simulator. I got 100% of these right. The idea behind the project is that they can build a picture of what level of deficiency can be classed as acceptable, instead of just a black & white approach. The current CAA approach is based purely on the fact that until recently there just wasn't a satisfactory enough method of establishing where you were on the scale of perfect to useless.
I was told that when the new system is adopted I would be one of the lucky ones to benefit from it as my defect is very mild. It's certainly reassuring to know that change and common sense are both in the pipeline.
The project is currently about half way through their sample subjects, so I would encourage anyone in the same boat as me to request the CAA pass your details on to City. By the way, as it's part of a research project, the whole 2 hour exam is free and at least you'll get the satisfaction of knowing exactly where you stand in the grand scheme of colour vision things.
HI .. Can anyone please tell me where i can do the Airfield signal light gun test.? I live in Vancouver Bristish Columbia now ......
I passed the Farnsworth test .. but wasn't able to pass the lantern test ..... I need to do the airfield signal LIght test because i am planning to pursue my career in Hong kONg . ...
i called transport Canada and my aviation medical doctor.... and they don't know any information where i can do that test...
Does anyone know the closest place where i can do the signal light gun test ..? ..
I have class one medical by FAA have colour problem, so had to take test to wave that from my medical. When I convert my licence to Canadian they honer that. I have a chance to get a job in India, my question is they will make a problem on this? or they will honer this?
Read the HUGE colour vision thread just below and you might find some more information. It depends on how Indian licencing works. If they will accept either your FAA or Candian licence then you will probably be ok, but if they don't and you have to take another medical my guess is you will have a problem.
Does anybody know when the CAA will begin standard colour vision testing with the new systems developed with City Uni? I want to take the new test asap to see if I might just be able to get a Class 1 medical.
I volunteered to take part in the City Uni trials, as have a few people that posted on this thread. My personal impression from talking to the lady that tested me is that the trial will take approximately 1-2 years to complete, not for the fieldwork but also to analyse the results, draw conclusions and make recommendations. Then there will likely be another period of delay while the CAA consider the recommendations and eventually implement some changes. So I got the strong impression that there would be no change to the current class 1 medical colour test for the medium term. By medium I mean certainly more than 1 year but hopefully not 3 years!
There is also a link somewhere higher up on this thread to a Flight International article speculating on when the new test would be introduced, can't remember but they thought several years away I think.
If I were you I would try to get yourself on the City Uni trial, and/or go for their standard colour vision assesment (which you have to pay £125 for). Depending on how old you are you most likely don't want to be waiting around for years for the CAA to change the class 1 test. PM me if you want contact details for the City Uni person running the trials.
Having taken the PAPI test myself I'm of the opinion I couldn't pass it when introduced by CAA. My CVD diagnosis is "Moderate Protanomaly"
Shunter (see post above) was diagnosed as "Very mild dueteronomy" and he could pass the PAPI test, so if you go to City Uni for a full diagnosis now you should have a good idea if you could pass it in the future.
cheers

I have been following the 2 threads regarding colourblindness closely and, while understanding that most of the discussion pertains to the CAA/JAA, I am hoping for some insight into my situation with Transport Canada.
Just today, I took the Farnsworth D-15 colour test where I flawlessly passed the first two tests administered and made one error on the third test administered. I then took the Holmes-Wright lantern test, upon which I was informed that my answers were inconsistent with the green/white colours being displayed. Upon completion of the Holmes-Wright, I then took the Farnsworth D-15 again to prove for a fourth time my competency in flawlessly determining the pattern of colours.
This then brings me to my question:
If I have consistently demonstrated complete competency and accuracy with the Farnsworth D-15 test (which is considered an alternate to the Ishihara, while the lantern is considered an alternate to the D-15), upon which grounds will Transport Canada consider my colour vision competency? Does the fact that I was completely successful with the D-15 indicate that I have meet TC's colour distinction requirements or will my failure on the Holmes-Wright lantern test outweigh my successes with the Farnsworth D-15.
Here in the states we can do the ATC Signal Light Gun test. I tried it today. I saw red fine but was kind of iffy on green and white. I need to practice some more to build confidence, or luck.
Has anyone seen a video of a tower shining an ATC Signal Light Gun? I know its not the same as the real thing but still wouldnt mind having it to look over.
Please post URL if you know of such a video online.
