Caa Restricted Medical and FAA Unrestricted

Can people who have a Restricted Medical fly Cargo Aircraft in day time hours? Does Cargo Aircraft count as public transportation? CAA states that you can do your Night rating with a Instructor at all time. Can the Captain of a Cargo Aircraft be your instructor? Thus letting you fly at night? I also have an Unrestricted FAA Medical is it easy to find a Job in the states if I did my flight training in America? Thanks for your help

Class 1 medical colour vision

So I have been to the CAA in gatwick today and failed the colour vision test, 1st the ispharia plates and then the CAD test. Now I no that its probably the end of the line with regards commercial flying is concerned, but it was mentioned to me about another test in America and Canada the signal gun test. Does anyone know Any more about this, or any other alternative ideas ? Is Australia the same with regards colour vision testing? An I now doomed as I have failed the ispharia plates and CAD or is their a chance I may pass the signal gun or fansbury lantern test. Any advice would be great.
I was sure I would have a chance of passing the CAD test as I already knew I wouldn't pass the ispharia plates, but it seemed their was a problem with the colour red. The colour issue has never really affected me before but obviously their is an issue with it.
All other parts of my medical were passed with flying colours so I am gutted.
Thanks!

Hi Rockets11
I failed the CAD at Gatwick (red deficiency) a few months ago- so I decided to go to City University, London to take the Holmes-Wright lantern and the Nagel Anomaloscope (the other 2 tests that the CAA recognise but don't administer themselves) - at City Uni they conduct several tests when you go, one of which is the CAD. Surprisingly I managed to pass the CAD there and failed the HW lantern and the Nagel Anomaloscope. Sent my results off to CAA and now I'm deemed colour safe.
I don't want to get your hopes up too much, but it might be worth your while going to UCL and getting these tests done there, if you pass either the HW lantern of the Nagel one then the CAA will deem you colour safe (you might even do better on the CAD). Keep in mind that the CAD test, from my experience, is dependent on how you perform on the day so make sure your feeling well and have had a good nights sleep. Second time round at the CAD, I took my time, had several short breaks in between each clip and managed to pass. If you want any more info, just ask!

I agree with you matt1991 I'm thinking of going to ulc, it's just getting there from up north! Also I agree with the taking your time as this is not a option at gatwick and I got so pissed off with the whole test after fifteen minutes

I had to travel down from Manchester (yeah, your quite a bit further haha..) so I can understand what you mean! I wish they did these tests in more places so it would be a lot easier for people who don't live in London!
At Gatwick I was told to take my time and take breaks but I didn't feel relaxed there at all. At UCL it was very friendly and so a lot easier to be relaxed and take breaks...

hey, my experience was different, i turned up for my renewal and did the cad last, the lady put the tv on and the laptop on and i went through the mockup test so i knew what i was doing, now bearing in mind that i was not told about the quick screen and was changed for the whole test, i was told to look at the middle of the screen and to press the direction, i was not given any breaks at all.

also what is annoying is that i scored r/g 7.44 so a straight fail, but was told that if i scored between 6 and 7, they could test me again and average the results out, ok fair enough, now i am being told that any results i have will be average into any other test results, that's not fair for a start.. and that came from the new head of medical section who has no idea what he is talking about, and certainly there i nothing in the medical that tells of this method to be used..

Well I just came back from several colour assessment tests at City University. To cut a long story short, after a couple of different colour tests, I went on to do the CAD test.

At first, I did the blue/yellow test, and I got a threshold of 0.79 - Better than a normal person with normal colour vision according to the lady. But then I did the red/green test... Threshold: 21 - Green deficient. Way over the limit. The lady herself looked and sounded a bit shocked when she came back into the room to see that result. Especially because she seemed fairly confident that I would pass the CAD test relatively easily and quickly. Unfortunately, that wasn't the case...

I have to say though, the test really is frustrating. Sitting in a pitch black room facing a computer screen seriously messes with your vision, and tires your eyes quite quickly - Especially on the longer red/green test (9 minutes). Also, I've got to admit, that I really started rushing the test and ended up clicking buttons as quick as possible, which might have contributed to such a bad result, but to be fair, I think I would still fail if I got a chance to do it again, as 21 is extremely high.

The CAD test really does move extremely quickly. In all honesty, it feels as if you have less than a second to look where the square block is moving to.

Nevermind. I think that is the final call now, and there will be one less pilot in the skies. It's extremely painful to throw away my childhood dream of being a commercial airline pilot, especially after saving up, gaining the courage and spending the money on my Lasik eye surgery to pass the vision restrictions to then find out I am colour deficient - At least I have better than perfect vision now.

All the best to you colour deficient guys & girls. It's not a fun experience to find out you are colour deficient just before you aim to start taking flying lessons. Good luck with your medical/vision tests in the future guys!

Smiless,
I know exactly how you feeling. The same happened to me in the UK when I was your age.

Know this: the initial tests you failed are standard colour vision tests. You can pilot a plane as safely as a person with normal colour vision if you were allowed to. The CAD test is just another test of colour vision and nothing to do with the task of flying - it's just a red herring, not to mention another way for your aviation authority to make money and keep you thinking they are trying to help you.

Your easiest option is migrate to Australia where court cases have had fantastic results. We have had colour vision deficient pilots for 20 years or more at all levels including international airline captains.

You should research avenues to get funding to fight a legal case within Europe.

Scottish.CPL: I scored 2 out of 25 on the Ishihara plates. And this was the first time doing the CAD test for me. I did one test for the blue/yellow (4mins long) and one test for the green/red (9mins long).

Outofwhack: Thanks for the encouragement & advice. I will look into migrating to Australia, but in all honesty, I've almost lost all my hopes of being an airline pilot right now. We'll see what the future brings. I guess I'll just finish off my Aerospace Engineering degree first before deciding on what to do career wise.

Smiless,

When you say you scored 2 out of 25, do you mean you made 2 errors or only had two 2 correct?

If the latter then that is most definitely a failure, however, if the former then we need to talk. Drop me a PM and we'll take it from there.

I have been informed this weekend of a person who passed Ishihara for a Class 2 medical then went to a local optician for a full eye test to EASA standards prior to the Class 1 medical at Gatwick and passed that, including the Ishihara test......yet, amazingly, s/he managed to fail Ishihara at Gatwick and was charged a further 125 for the privilege of taking the CAD Test, which was passed.

Personally, I am very suspicious as to what is being allegedly perpetrated here.

i recon the plates at gatwick dont get replaced, ive been to gatwick a few times over a period of time and its the same crappy ripped cover..

and to point out that the plates are very sensitive to light and saturation, and so if the plates are old and worn, any small level of the plates being faded is going to cause issues even to anyone that might have a slight colour dificiency,

ive been to opticians and passed the plates random, been to university eye clinics and got the same results, but every time i have done the plates at gatwick i struggle..

No not much happening.
Here's a few topics of interest:

1. A few aviation doctors I have talked to in UK
and Oz admit that during class 1 medical renewals
where the Ishihara cards are shown to
existing commercial pilots they will make
the odd mistake too - but they overlook it
because it is a demanding test and colour
normal people will make the odd mistake.

2. A UK perception scientist Dr Beau Lotto
admits that in some circumstances a
colour can appear as another colour. Search for
him on YouTube. It's very interesting.

3. An appeal court case is in progress in Australia. See CVDPA

OOW

Ok, right i have a question for any one that is an ame on here,

with regards to the lapl colour vision requirements,

say you pass the plates but not to easa req 15/15 but you pass 13/15,

you go to a medical exam for lapl and you have proof on paper from a optician or university showing this, and you want a night rating, would caa accept this,

ive taken cad and failed, not sure to repeat this..

I'm not an AME, but AIUI a 9/15 pass on a LAPL medical allows you to add a night rating to a LAPL. Since higher level licences (CPL PPL) have lower licence privileges embedded in them, it should theoretically be possible for a PPL/CPL to fly at night using their embedded LAPL privilages if they have a LAPL medical and 9/15 pass.

However, are you allowed to have more than one medical certificate, or would you need to give up your class 1 or 2 certificate in order to get night privileges?

This crazy situation just shows how stupid the current system is.

Further reading of the AMCs reveals this:-

AMC1 MED.A.030 Medical certificates
(a) A class 1 medical certificate includes the privileges and validities of class 2 and LAPL medical certificates.
(b) A class 2 medical certificate includes the privileges and validities of a LAPL medical certificate.
So a 9/15 pass should be enough, but I am not sure if there is any mechanism for adding a conditional night rating, ie "valid only when exercising LAPL privileges" on to an EASA CPL /PPL.

How serious is the Ishihara Test?

Dear Forum,

I've been interested in becoming an Air Traffic Controller for a long time now and decided to finally make the move. As I was going through the 'How To Apply' section on NATS' website, I noticed the medical tests and was not worried about any of them as I have no history of health problems. But then I got to the visual tests and noticed something I've never heard of; Ishihara Test. I started searching for more details about this test and have come to a reasonably strong conclusion that I'm fairly colour blind.

I'm quite shocked about this outcome as it seems to have come out of nowhere. However the colour deficiency has never once affected my real world performance. I've passed my driving test and am a competent driver. I also went in for an eye test before knowing of this condition and passed with flying colours (however they only tested for visual acuity - viewing distance). Do I have any chance of becoming an Air Traffic Controller for NATS?
