Simulators are great things but for something like colour blindness I think that we should understand the actual environment and not a simulated environment

What is the difficulty in flying a real aircraft at night with a CAA examiner who conducts some objective tests to see how the pilot does (pilots who are CVD would foot the cost and at least it is a real world practical test based on real world operations and environment).

As one who had done the new test at City it is different. There is a link to it somewhere on the web which I will try and find and then post.

The research at City has been ongoing for a little while now - I'll give them a bell and report back to you all.

Here it is:

Click on the biggest of the 'greyed' squares and it will come to life to give you a preview of the new test.

gijoe - Thanks for the link which is very interesting

The test looks good but my point is that it is simply another test to diagnose this condition (albeit a more fun test). I know I have an issue with night colour vision (white / green ) in some situations (not all obviously or I wouldn't be safe at traffic lights etc).

What I would like to see is a test involving a night flight where safety is judged by an examiner based upon the successful operation of an aircraft in the night environment.

P.S. Just got my ever loyal wife to double check me on this new test and I can see all of the colours all of the time and correctly !

Fingers crossed !

Be careful as the actual test is different from the one shown on the link. That one is for demo purposes only.

The real tests produces 3 overlapping ellipses that give an indication of where your weaknesses and strengths may be. 'Normal's will have a small overlapping area in the middle of the ellipses whereas a CVD will have a bigger area as they are unable to distinguish between some of the colours.

I have tried to contact someone at City but my email got bounced back. I'll report later.

Hi guys.. the test from City University is one that they have developed recently for identifying CVD´s, it is just another color vision test.. It has nothing to do with the one they are working with now. I´ve done it recently and CVD´s just don´t pass it. Besides, it´s not a valid test as per JAR-FCL.. it is just for their evaluation purposes.

Beware - don't confuse this with the City Uni test which is 5 dots arranged in a cross pattern where you then have to identify the odd one out.

This is totally different from the new unaccredited test.

The old colour thing

Hi guys,

I read back a long way in this forum and there is so much info.

Myself, I have a slight green CVD and confuse certain greens with white. Of course never in real life, just on a lantern!

I have done a lot of my own research into the subject and have read so many things in so many different places. Some have caught my attention such as the shades of greens used in aviation as appose to the ones used in traffic lights (I have read that the green in traffic lights is specifically chosen so as to appear green to more CVD's) I bet this isn't the case in aviation! (and incidentally I don't know if this is true of traffic lights but they always look green to me)

I personally have an unrestricted FAA medical after passing a lantern test (not sure which one) with no faults. But guess what? I failed the CAA one. I have also been for tests at my local opticians where I passed colour normal on the 'hue test' (not ishiara which I always fail but not by far) and have spent endless nights looking out to sea and asking friends/relatives to verify the colours I see are correct! (and they are)

I have read that the CAA plan to bring in a new test soon and all I would like is a world-wide standard that is fair (as per Arthur Papes research) and not just another test to weed out us unfortunates. I too have taken the test on the city university web site with no problems at all.

What is clear by looking back along this forum is that all we seem to do is talk about it. This forum goes back five years and what's changed? Anyone made a difference? I'm not saying I could but I'm sure a few of us could. Why don't we all chip in five hundred quid each to get some research done? Or at least pursue some legal angle on this. I talked to ACASS recently who told me it wasn't classed a disability because it didn't affect our everyday lives (and I'm not for one minute suggesting were dissabled) But I'm sure we could look at other angles. What about changing all green lights to blue! I'm sure that will attract a multitude of reasons but it would allow a lot of CVD's a chance to distinguish nav lights. It's only a bulb!

Personally I have to make the choice of going to the states and biting the bullet to do an FAA commercial hoping I might get a job in an FAA jurisdiction (marry and American) or in an N-reg plane. For a lot of investment that is a huge risk to take. The other option is to try to get something done about these rules or at least get some standards set so I wouldn't have this dilemma of whether to go to the USA or not.

Incidentally the CAA won't tell me when they plan to introduce a new test and the City University don't reply to emails, but why not try as well.

I am looking into the possibility of taking my medical in another JAA country so if anyone has any info in this please PM me. Perhaps we can at least set up a web site to get as many people with CVD's passed as possible by offering information and address's/hotels/directions and booking details for medicals in other countries and what type of tests they do. In fact, thinking about it, all we would need to do is get one place where you can come and take all the tests, see which you pass and then point you in the direction of the country/doctor who conducts that particular test. We all know these rules are absolute Boll**ks so lets do something about it!

Hope this thread has been helpful.

Geat idea,

Nothing happens because we cant do anything to it!!
Rules are Rules and the JAA is one though bitch!

If you want to have some influence you need 3 things!

1. money
2. time
3. a team of investigators

We all want to pass the test. Some of them would even cheat!!
I can understand that. Why is it possible to fly day and night on the biggest aircraft in australian airspace and not in european airspace?? Why is SODA valid in US but not in europe??
Invstigation is not neccecery because it is proven that a SODA is SAFE!! The FAA used it since the early days of aviation.

The only thing that we can do is fly SEP's during daytime.
No IR and no CPL!!
It is really un******* believable!!
I still can get pissed off if they tell me: due to CRT's its more difficult to distinquish colours so an error is possible.
And you could have problems with PAPI. Those people dont know anything about flying!

Ever heard of an ILS??? or VOR/NDB???
Proffesional pilots dont use PAPI! And if they fly VFR its a nice backup to check your glidepath but not neccecery!!

Investigation is no pre because there are enouch pilots without a job!

The only thing we can do to hope for a miracle.

any info is always welcome.

Chris,

I can't speak for the idiosyncrasies of other JAA states but certainly in the UK, even with a CVD you CAN hold both a CPL and IR with a deviation on your medical restricting you to daytime flying and No Public Transport. But you can fly IFR and you can do some forms of aerial work.

I have never had any problems in actual flight conditions, with runway / taxiway lights, VASI, PAPI, tower signals or recognising aircraft colour lights but with current standards I am unable to obtain an unrestricted JAA Class 1 medical. That is not the fault of the CAA, they merely apply the standards that have been applied by JAA - it is the standards that need to be questioned.

It is very easy to design and use an unrealistic test that will classify people as 'Colour Unsafe'; what is needed is an objective test that is based on practical situations and what could be more real than a test at night in actual flight conditions. However, I accept that it may not always be pratical to test under actual flight conditions but I do not believe for one second that, in this day and age it would not be possible to create such conditions in a purpose built simulator. What prevents that? Simple, cost. Why should the powers that be go to the time, effort and expense of creating such a beast when they have an inexhaustible supply of non-CVD wannabees ready to fill the vacancies?

What are the discussions between JAA and FAA about? I don't know (I am not a mole or any other form of nocturnal mammal.....as a CVD I'm not allowed to be, even the rodent world has its standards!) but if its simply a case of accepting a common standard I wonder which way the pendulum will swing. Will the FAA move towards the more stringent testing standards of the JAA or will JAA swing towards the FAA standards? Only time will tell but I wonder whether the NTSB's recommendations following the Tallahassee incident will have any bearing on the decision.

The next question is, assuming the FAA went for the JAA standards, how would the decision affect current pilots? Would grandfather rights be transferred or would all FAA Lantern Test / SODA holders be required to retake the new test - what sort of an impact would that have? I have no idea of the actual figures involved but if the FAA went for the more stringent testing and required all Lantern / SODA holders to take the new test, given that 1 in 12 Caucasian males is CVD then potentially the USA could stand to lose as many as 8% of its pilot force overnight (assuming pilot numbers follow population trends) and I don't think that is going to happen. And if the standards went the other way, would that mean that holders of unrestricted FAA medicals would automatically qualify for unrestricted JAA medicals?

I think the reality is that we will be looking at some form of new test, as designed by City University, being adopted on both sides of the pond but as for existing CVD pilots with deviations or unrestricted medicals, who knows what the future will hold?

I suppose it's a case of 'watch this space' but I for one will not be holding my breath.

NTSB

ha 2close,

I heard of the Tallahassee accident. I read the peace yesterday.
The NTSB conclusion is rather strange. They believe that de FO's colour weakness is the biggest cause of the crash. But that is not certian. The Capt. en SO told the NTSB that they also saw a positive PAPI. The only difference is that they saw it as white, pink, red, red and the FO saw it as white, white, red, red.

And because the weakness of the FO is the only realistic thing to blame, he is the bitten man! The pilot passed the Falant and failed 7 other tests. Ok thats something to consider. But the milliondollar question is??

why did the other 2 pilots also saw a positive papi indication?

This man has a flying history for more than 20 years.
Nobody ever doubt about his ability. Why should this be his misinterpretation? I think the statement of the other 2 pilots is vital in this peace. But thats my vision.


2close

I will ask the JAA about a CPL. I would like to become a FI.
With a CPL thats possible. Although is only for ppl at daytime I would like to do that. It is a nice way to earn your money and you improve your flying experience.

Good luck to Ya'll

Greetzz

It's nice to know that I am not battling alone and that you guys are also giving CAA some sh?@t

Great thread so far - I suggest we shame the CAA into action by forming a pressure group and using humour to point out the ridiculous illogical contradictions imposed on us - Group to be called - "Vampires" with some witty acronym such as Vampires Against Bull**** (VAB) - Can anyone think of a funny acronym ! Anger seems to get anger in response hence the suggestion to try and get a laugh out of CAA.

2Close - Totally agree that we need a practical test for pilots to determine if competent at night and yes you are right you can invest in ATPL, CPL, IR etc but that is a hell of an investment for a license that restricts you to the point that you cannot practice your profession like everyone else (perpetually stuck in training others for something that you yourself cannot ever do?) - Banner towing sounds fun for an hour or 2 but not as a longterm career move.

We could also turn the tables and get some press attention by organising a mass "breaking of the rules" to focus attention on this issue "Vampires for justice?" - What about an organised group mass flight which will land 5 minutes into night dressed as draculas complete with false teet and fake blood !

Benefits of this mass law breaking:
1 - CAA to foot the bill to get us all into court
2 - Publicity and awareness of our issues
3 - We can then challenge CAA by defending ourselves as a group and using our individual circumstances to tie CAA up in illogical prosecutions
4 - Gain support from AOPA and our fellow pilots to stick it to CAA if they decide to proceed (which I very much doubt !)

Not bad I think for a few minutes brainstorm, I for one think it would be a great laugh and would make a valid and humerous point (pleased don't respond with safety concerns or I will just drive a stake in my heart right now and head on back to the coffin)

If anyone has time to organise please PM everyone on this Forum and we can take it from there

Just thought that we should try a softer and more humiliating stunt first and see if that helps our cause without risking our licenses just yet - Suggest we all meet at CAA headquarters at 09:00 am one morning dressed as Dracula's with banners - chanting "Draculas for justice" - obviously beforehand we send press releases to AOPA, PILOT MAGAZINE, FLYER ETC so that we get global coverage and support - we could then make sure that our press release gives a balanced and reasonable case for changing the current regulations.

THIS WILL WORK AND I FOR ONE WILL TURN UP DRESSED APPROPRIATELY IF WE GET AT LEAST 20 OTHERS !!!!!

Like the idea! It would definately get the attention of the press. Stuff like that does actually seem to work. Im in!

On a more formal note, does anyone know what is happening with the city uni test? That seems to be dragging on. I tried to email the woman at the Uni but got no reply. I'm sure she is sick of people asking. All the CAA will say when you ask them is to keep checking their web site for updates.

Will keep trying.

OK Thats 2 in - Only 18 to go

Heck 10 is a nice even number so we need only 8 others !!!

I will happily co-ordinate things and I would definitely like to see the media and press in attendance, this is the type of thing that attracts camera crews and raises our profiles. Do we have any savvy media experts in our midst ?

I know its a bit daft but it would get across a serious point in a fun way.

LETS SEE HOW STRONGLY PEOPLE FEEL ABOUT THIS !!!!!

Prefer to do this in September if possible and I am passionate enough to make it happen (with help from others of course)

I'm surprised by the comments about City University not being very helpful-I've found totally the opposite. I recently had a full colour deficiency test (cost £35) and they have been very helpful-replying to my e-mails asking for furthr interpretation of the results etc. The university is not a free source of info for 'disabled' (joke) pilots. Their tests may not help you get a restriction lifted but at least you'll know the extent of your deficicency.It appears to me that they are looking at the science how it's interpreted by the CAA/JAA is another matter and I think that is what their research -due to start later this year will look into-namely what part does colour play in aviation! We all want to follow Papes-and I see no good reson not to-it's illogical to have different standards depending on the letter painted on the aircraft! I'm not for lowering a standrd just changing it to one based on the practical requiremnts.

As for protesting-I'd give it a go-I used be a reformist-persuation by argumnet-but I now believe you also need revolutionaries to make change happen-let's revolt! (see the poll tax!)

CVD Makes the band of revolutionaries number 3 !

Nice defence of City University - When I spoke to one of the people at City It was clear that they knew how to interpret and how to analyse results in a logical way, unfortunately the logic did not appear to include any analysis of how pilots might cope or deal with the deficiencies in a safe way. E.G. No study of US (The pilots) and how we cope (or not). When I suggested that any decent analysis or testing would include analysis of the current CVD pilot population in real world scenarios I could tell that eyes were going blank ! I agree CAA should be analysing pilot population but unfortunately they can't be ars$d because there is no money in it for them so hence status quo remains.

Phew! that feels better !

Colour Vision!!!

I recently obtained an ICAO CPL with IR. Although I only passed my class 1 after extensive colour vision testing, (failed the Isihara plates), I had to pass 2 lantern test's (farnsworth and holmeswright and a diagnostic test) before being given the ok!

My question is this, even tho' I was given an unrestricted class 1... What kind of problems will I encounter in the interview room with prospective employer's?

Any insight / views into this greatly appreciated!

Cheers,

B.

If you have an unrestricted class 1 medical why do you anticipate any problems ? ICAO do not issue licences, so you must have one issued by a national authority whose government is a signatory to the ICAO. I always think it draws attention to oneself when claiming to have an "ICAO licence" it suggests the issuing authority is not relevant to the country of application ?

Interviewers are not likely to question or scrutinize your medical certificate unless there is some restriction or endorsement on it that excites their interest. I cannot see the medical aspect causing you any problems unless they all turn up in multicoloured sweaters with subtle numbers weaved into the fabric for your entertainment.

Why do you think this might cause a problem ?

I had the same problem as you with the isahara plates however having passed the lantern tests 100% i was awarded an unrestricted class 1 medical. Been flying regional turbo props for the last 3 years, just moving on to my first jet and the medical has never been an issue. You like me have been deemed fit to hold a class 1 medical and as far as the colour deficiency is concerned that won't change so don't worry.

Hi guys,

I've got a question and was hoping someone on this forum might know the answer. I've got a mild green weakness and have been flying in Australia for 5 years. 2 years ago I travelled from Australia to Switzerland and passed a class 1 medical. Since then I have been back in Oz flying around in transport category aircraft. I recently sent my JAA medical details to Gatwick and they have issued me with a CAA issued JAA class 1 but have advised I must do an extended eye examination at the next renewal. Has anyone been in this situation. In JAA states is colour vision continually tested or once declared colour safe is that it? Has anyone been is this situation?

Thanks in advance and good luck to all others wanting to fly with this condition that has been proven safe to fly with.
