UK CAA Policy for Deviations Updated June 2010
Until the implementation of EASA Medical Requirements, the policy of the CAA is to assess for medical certification to JAR-FCL 3 standards. Where one or more of these standards is not fully met, but an equivalent level of safety can be demonstrated, the applicant may be assessed for a JAR medical certificate issued as a Deviation. In this case, the medical certificate will be endorsed in accordance with JAR-FCL 1.015. The CAA will not issue Deviations which jeopardise compliance with ICAO. Accordingly, these medical certificates will be fully ICAO compliant.
JAR medical certificates issued by the UK CAA as Deviations can be used to validate UK-issued pilot licences and restrict the holder to flying UK registered aircraft only.
For the purposes of this policy, if a Deviation is likely to be removed, it is described as ‘short-term’ and if it is likely to be permanent it is described as ‘long-term’.
Use of Deviations
The CAA has identified a number of areas where Deviations may be considered.
1. Where there is a different initial standard from the revalidation/renewal standard
The most common use of a short-term deviation is where there is a difference between the initial and revalidation/renewal medical standard. If the need for the difference in standard is due to a different anticipated adverse effect on flight safety of pilot incapacitation of an inexperienced compared to an experienced pilot, the UK CAA will accept the mitigation of risk that increases with experience. In this circumstance an initial certificate may be issued with a Deviation (allowing flying training to be undertaken in the UK) with a view to removing it once appropriate experience has been gained. The UK CAA defines this experience as being equivalent to completion of flying training to the licence standard and demonstration of competency in the skills test. The Deviation can thus be removed at licence issue if there has been no progression of the medical condition.
2. Where medical evidence and medical developments support an equivalent level of safety
A long-term deviation may be issued if new medical developments support the issue of a medical certificate which is precluded by JAR-FCL 3. The UK CAA will, in this circumstance, contribute to the medical rule-making process to propose an amendment to the medical requirements. If the medical requirements are subsequently amended, the Deviation may be removed if the requirements allow the condition or treatment.
Revalidation/Renewal of a Medical Certificate issued as a Deviation
Pilots with a Deviation on their medical certificate and/or licence should attend for revalidation/renewal with a UK approved AME.
*Important Caveat
Following the implementation of the EASA rules (anticipated 2012-1014), it is possible that EASA may have the power to revoke medical certificates issued as a Deviation. Holders of such medical certificates should be aware of this risk.
Certificate holders who are eligible for the removal of the deviation on gaining their licence should aim to have achieved this prior to the implementation of the EASA requirements.

Suggested text to be included in letters issued with medical certificates issued as a deviation:
I am pleased to assess you as fit for JAA Class … medical certification issued as a deviation. Your deviation is to be considered *short-term/long-term (*delete)
Your medical certificate is ICAO compliant and is valid on UK registered aircraft only. You may use it to exercise the privileges of a UK licence in international airspace. However, if you wish to fly an aircraft registered in another state, you will need to obtain the permission of the licensing authority of that state.
Please note that the European Aviation Safety Agency is developing medical requirements that are likely to be implemented in the UK between 2012 and 2014. As your medical certificate, which has been issued as a deviation, may not be EASA compliant, you should be aware that there is a risk to the maintenance of your medical certification beyond this date.
Our policy regarding medical certificates issued as a deviation is enclosed, and I draw your attention to the guidance regarding types of deviation and how they might be removed.

Is learning the Ishihara-Plates even possible?
Hi there!
First of all I gotta say it´s to late for me anyway
However as I saw some of you recommended learning those Ishihara plates - I wondered whether that is really possible? Can you really learn them and pass? And why didn´t everybody in here (at least those who know about it) do so?
regards

colour testing
Hi, i held a PPL back in the 80's which i let lapse, at the time i had a class 3 medical but initially failed the colour plates and went to CAA for a lantern test which i passed.
My question is, if i now try for a PPL medical again which i think is now class 2 would i be tested on the plates again? or as they have been passed previously would that be sufficient to pass this medical.
Are the standards the same for a NPPL
Does colour blindness get worse with age?
Any help appreciated as i'd like to get back into it if possible, although its probably a case of when you can afford it your healths gone!!!! catch 22
Thanks

the issue that most cvd people have, is that the ishihara test plates need to be tested using the proper methods, ie, updated plates and the proper lighting.
is the test was administered as the istrauction were set out, ie, the instructions states, that if 13 or more plates are read correctly, then the colour vision is classed as normal or cp2. The RAF set the standards to the full 15, but remember this is due to the selection for the RAF being high so i can understnad that element, but the Army and the Navy state 13 or more..
what makes me laugth is that to become a train drivewr, police, or firebrigade, pass the plates to the instructions, but CAA/JAA, hah no . the cad test is a joke, i believe people who failed the cad can resit after 6 months, please correct me if im wrong or right on this..
You could learn the plates but, the authority would have to show the plates in random order to eleminate cheating, which is not good, cause if you are going though the plates and you give the complete wrong answer, ie an 8 on the plate and you say 29, you look a complete idiot...

So it is possible that individuals who have been working in aviation for years on deviations may, at the stroke of a Eurocratic pen, lose their livelihoods.
I admire the way in which CAA Medical states that EASA may be able to revoke the Medical Certificates, giving the appearance that EASA and not the UK CAA is responsible for whatever happens.........when it is the UK CAA that is chairing and steering the EASA Part-Medical Sub Committee.
I wonder when someone down at Gatwick is going to develop a backbone and start telling the truth.
Then again, why change the habits of a lifetime?

I am one of the "deviants" with a restricted Class 1 and an ambition to become a flying instructor. I am working on my CPL and will be starting my FI rating soon. I am aware that the EASA change may make life difficult for me, but it would be incredibly unfair if they were to revoke my earning priviliges (by denying me a class 1) for no safety benefit.

CAD Test
Hi,
Can the CAD test only be taken at Gatwick or is it available in other locations?
If only Gatwick, anyone know how much it is and what sort of waiting list for appointments here is at present?
I previously passed the lantern test with CAA in 1987 and got an unrestricted Class 3 for a PPL, would i need to pass again using the new CAD. Guess i'm saying if you manage to jump the hurdle in the past is that it or does colour blindness get worse with age and require regular testing?
Thanks

Hi
The CAD is Gatwick only; the waiting time seems to be about 2 weeks but you should give them a call to find out. £130.
Colour perception stays the same over time (unless you've got something wierd going on) so you only need to do a colour perception test once, so your lantern test might still be valid if you've kept your medical current. By the same reasoning, if you fail the CAD it's failed forever.
Re learning the Ishihara plates; I can see something in all but one of them but on some its unclear- in my case trying tests online got me used to what the unclear ones were. My intention was not to cheat- I'd booked myself in for the CAD after all- just to get an idea of how bad my colour perception was. Not that bad at all as it turns out!
Well, I'm not sure about the 100% bit, but I'm going to trust City University's published research over any second hand anecdotes 
(I don't mean that to sound bitchy, I just like solid evidence).
The test goes as fast as you want it to go. They explain before you do it that if you want a break, just don't press the button. It only goes on to the next square once you've selected which direction the last one went. And like you say, it isn't easy. Like the hearing test (which I did on Wednesday, passed my class 1
) it's designed to be difficult. Take your time.

Now the CAD test, the option is that this test is supposed to be and this is what CAA say and City university state 100% accurate, i laught at this cause no test on the plannet can give you 100%, thats like saying to the CAA, produce a pregnancy test, which is agian 100%, cant happen, subject to human error and other factors. They state the cad test is easy, its not, and the test itself goes at a very fast rate and they say it is presented on a gray pixalised background which flickers, will it does flicker but not a grey nuteral background.

I would wholeheartedly agree with your sentiments over trusting solid scientific evidence over anecdotal comments..........unless the supposedly scientific research had been conducted in such a manner that it would produce desired results.
Unless a full study is conducted over a large sample of subjects, including full investigation of all reported problems, in particular safety related problems, NO test is valid.
I can give you a 100% cast iron guarantee that NO investigations took place over reported safety problems vis-a-vis adverse side effects with the CAD. These were reported verbally at the time to the staff and subsequently in writing to the relevant persons but dismissed out of hand with no investigation.
I have no doubt that it was feared by the relevant persons that any investigation into possible safety problems may delay or even prevent the release of the CAD and as such it was decided to accept the risk of causing harm to persons over a possible lack of financial revenue from the sale of the CAD.

well first of all, i did not write the article as a point of blame. I am mearly stating the facts on this.
Im also going to ask to redo the tests, i believe you can retest after 6 months not for ishihara but any secondary if felt the tests were not conducted fairly.
the benye lantern was done and will as holmes, but i was not given night adaption nor was i advised the 3 runds of the lantern would be done in one.
i will fight for want i believe is right.

Cathay Color testing
I was just wondering if anyone knows the color testing process for the Cathay Pacific cadetship?
I hold an Australian class 1 medical with no restrictions, however in my initial medical I was shown a number of pictures with numbers (I think it is called Ishihara by what I read on the forums) and I got 2 of them wrong. The DAME told me that I was color safe for GA, but that I might have problems getting into the airlines as their testing is more rigorous.
I currently hold an Australian CPL + MECIR with 200 hours, and not once did I have any problems associated with color decoding (day/night ops). I'm planning on applying for the Cathay cadetship, but I'm not sure if I meet their color vision requirements. Could someone please share some info with me? Thanks.

Hi all,
I've recently been looking into doing the CAD test as I know I have trouble with my colour vision just not really sure as to the extent. I have found however that the CAA isn't the only place it can be done, it can also be done at City University in London as part of a full colour assessment.
The cost for doing the assessment at City is £125 +VAT however they do more than just the CAD. I do however have a couple of questions about this if anyone might know the answers.
1:- Should I pass the CAD at City, does anyone know if this is acceptable to the CAA and therefore not require me to retake this test with them as well?
2:- On the flip side should I fail but only marginally would I be able to go to the CAA a week later and take the test there again as I know there is a 6 month wait if you fail at the CAA before they allow retests?
Anyone wishing to contact City about this the link is here:- Colour Vision Clinic - City University London
On a more personal note I've wanted to be a pilot since a very early age and failed the RAF medical on my colour vision but only just. I've only just again started looking into becoming a pilot again and the news of the CAD test gave me some, albeit small, hope that I could finally pass a medical (before then it was always a kind of 'no I can't do that because of my eyes' attitude, I took a fail as a fail for good not as a I could pass the next one as it was that marginal!). I'm 30 now so I'm guessing sooner rather than later would be best to start doing this otherwise I could end up being too old! lol
On a different note, are there any height restrictions on Class 1 medicals?! I'm 6'5"!
Cheers all!

welcome, and this should answer so things.
u applied to the airforce? u failed colour vision for pilot cp2 no mistakes on ishihara, did you do the lantern, would class u as cp3.
if u do the cad at city, caa in practice should accept these, they might as u do ishihara again.
the other thing is that the cad test is under debate, most people feel that the test is unjust, because when you do the test the person says to you just press the button in the direction of the motion of the square, and they say if you in doubt GUESS???
i find that completly unacceptible myself, ive done the test, and found it horrible, 15 minutes staring at a tv linked to a laptop, and a dodgy remote control.
you could pass it at one point and fail the next, its not proactive.
best of luck, but to be honest are you sure you want to progress in a flying career..

Thanks for the reply.
I do see peoples point about the whole 'being told to guess' if they are unsure about the direction on the CAD, however I would also say that it's surely no worse than someone 'learning the Ishihara plates' as has been suggest a few times in this thread? You could be completely devoid of colour vision but if you have learnt the plates well enough not get any wrong, which as there are only 38 on the test surely makes it less reliable than the many passes the box makes in 15 minutes of the CAD? Just a thought.....
Don't get me wrong I can see both sides of the argument, the bottom line is that no matter what test they bring in someone will find fault with it. Simplest answer in my opinion is to change the way colours are relied on in aviation (clearly this would take a LOT of work by a LOT of people), this would do away with the whole argument.
On another note, just out of interest what makes you question if I'm sure its what I want to do? I've wanted to do nothing else since I was about 10 but naively accepted that once the RAF told me no, that was it I had no future in flying, I've since learned that this may not be the case so just curious as to what made you ask?

hi, well the reason is that i am the same, i can read upto 13 plates and as per ishahara instructions that is classed as normal cp2, but caa and raf have other plans, u can be an army navy pilot, train driver, all that stuff, but fly an airliners NO.
i wanted to fly all my like and i did, i got my FAA CPL cause im classed as normal under the FAA and they allow more errors, ive got no soda(statement of demonstration of ability) cause my CV is normal but the standard for JAA is to high , even the head of medical branch admitted this to me but i powerless to do anything (POLITICS again)
the cad test is no good, and they say 100% accurate, bollock, if you see the box to right and changed fast and you press the botton right in mistake, there is you human error right there, and how do you know if the remote that is used with is a blue tooth thing is picking up the signal, should i not be connected to the laptop to avoid this....
mate these are the fact and i dont appologies for the direct approach answers but see when people say things on pprune about statistics and probability, TAKE THE TEST. lol....
anymore questions feel free to ask buddy,

No worries on asking direct questions as long as you don't mind a direct answer 
Thanks for the input though. Like I say I do agree to a certain point on the CAD test however like I said before I don't see how it can be classed as less reliable than a test that you could effectively learn the answers to. I am of course assuming that although you might be able to guess the answer on the CAD there is no way to learn each and every directional answer for the full 15 minute test?
I do fully intend to take the CAD probably next month, but at City rather than Gatwick, mainly because my CV is the biggest question mark for me as I honestly don't know how good or bad it is and City will give me more results from more tests and a better idea of the severity. This was the reason for asking if the CAA would accept these results if I passed. Didn't want to pass it at City to have to then go and have to do the same thing at Gatwick...... that said if I had to I'd do it if it meant gaining the Class 1!
I do have some questions about the testing process for the CAA though for CV. Is it just the CAD now? I.E. when you walk in they say they're going to test for CV and all you do is the CAD? Or do they do the Ishihara's first then make you do the CAD after if you fail that? Or do they do both regardless of if you pass the Ishihara's? If they do both do they take any notice of the Ishihara's at all if they base the granting or denying of the Class 1 purely on the results of the CAD alone from a CV perspective?

well the caa website still shows ishihara first and depending on the results, pass gr8 fail CAD.. how do u perform on the ishihara test then? have u done any lanterns yet. well people in the past, and erm in the present have passed the plates by memorising them, but i would assume that any doubt in that area, the plates are done in random order to prevent this, but the most IMPORTANT thing is the lighting, i have a sight green weakness, and yes people will confirm that it plays a big part in the test, u need to do the test in a room with no floresent lights, ie no yellow, cause it makes issues.
ive done the plates and i have also redone them for another profession, and they used brand new plates and read everyone of them, and also a version that was a printed book and there is a major difference, even when i did the book and passed, there was another guy and he really struggled with it and i was amased that it was not a fluke, the bases with caa is that the plates look old and falling to bits, ie old a faded..

Thats part of my problem, the last time I did the Ishihara's was when I tried to get into the air force, from what I can remember the examiner only showed me a few plates and I after i got a couple wrong he stopped with them and went onto a lantern test. I was borderline on this one, but he failed me on that too. Oddly enough though it was the white and green that i was mixing up not the red and green. I don't think it helped that I'd never seen a test like that before and didn't really know what to expect, and the white light he was using was a long way from white.... although I suspect that would be the same with all of them.
I think now I know what to expect from a lantern test and what they class as white I'd probably find it easier to pass. From what I remember also about the Ishihara's I did (this was a while back though!) on the majority of them I could see both sets of numbers, i.e. I could see the one that normal colour vision people see, but I could also see the other numbers that colour deficient people see, which is odd to say the least. On some the normal number stands out more on others the colour deficient number stands out more, but like I say on most I can still make out both. I do definatly agree with the lighting aspect as I did it in an artificially lit room which wasn't great.
Guess I'll just have to see what the results from City say.
