Shgsaint, we call those approach lights T-VASI. We use those and 4 PAPI in Australia.

I'm an EU citizen, and I've got more than 1800hrs Multi Engine Night Command and 600+I.F flying all sorts of aircraft including commuter turboprop, and it drives me nuts that i can't even fly a PA28 at night or IFR in the EU!!

Bring on the PAPI tests!!

Those are the ones!

Very easy to determine your glide path from my experience.

Cheers mate.

City uni tests again

2Close, I agree there seems to be mixed information, I'm not doubting what you say for a moment, all info welcome to try and work out together what is going on!

Here is a relevant extract of an email I received yesterday (14/08/06) from the lady who did my tests at City uni:

".....As explained to you we are carrying out a new study to eventually assess what level of colour vision is necessary to perform certain tasks in aviation environment. The tests have been finalised and I've started to test some people on them, especially normals. About 2 hours of testing may be required, probably less. If you would like to participate let me know and we can set up an appointment."

I think she's pretty keen for volunteers for this, both with known CVD and normal colour vision, anyone who is interested to know more please PM me.

(Please note I'm in no way associated with City Uni - just your average wannabee trying to work out if he's got a chance). Although I dunno why I'm bothering anymore seeing as I can't get that class 1.....

On a more positive note at least I'm starting my PPL proper this weekend at Stapleford!

cheers all.

Strobe lights, my guess is that;

your JAA country where you failed can do very little to get your current medical, issued by another state, revoked. If you have been issued with a medical certificate they really can't revoke it on grounds that were known when it was issued. Besides, another JAA member state has as little authority over other JAA states as you and me.

The country where you failed your medical could theoretically invalidate your (future?) flying licence when exercising the priviliges on aircraft registered in that country or, which is even more far out, prohibit you to fly in their airspace. I would say that the first example is against the EU principle of accepting each other certificates (especially since both are JAR) if both countries involved are an EU/EEA member. The second example should be against the ICAO convention since you meet the minimum standard outlayed by ICAO.

So in short, you should have now problem even though the country where you failed might give you a legal challenge in the future. However, do they require that you tell them that you use your JAR licence on their aircraft? If not, they will probably never find out and hence no probalem.

Thanks Martin.. but, how can I know this for sure? I mean, I might end up flying all over EU and suddenly this JAA country appears with a legal challenge against me (or against my Medical Certificate or Licence).. My AMC Dr. told me not to worry as he knew that I had a problem (I aware him) and that I shouldnīt worry about ticking yes or no, it wouldnīt change anything in my medical examination. How can I know that I wouldnīt get my medical revoked later on? I know that it will be against the EU principle of accepting each other certificates (especially since both are JAR) if both countries involved are an EU/EEA member, but shouldnīt they accept the JAA Medical Certificate that I have now and they are not? Itīs all in JAR but still.. some national authorities do what they please !!
Iīve read about some similar cases like mine but my question is if they finally received mutual recognition even with a previous denial?

CAA Paper 2006/04 Part 1: Minimum Colour Vision Requirements for Flight Crew: The Use

CAA Paper 2006/04 Part 1: Minimum Colour Vision Requirements for Flight Crew: The Use of Colour Signals and the Assessment of Colour Vision Requirements in Aviation
I haven't read this yet - just downloaded it so far (I'm a bout to go to work)

Go here: http://www.caa.co.uk/application.asp...detail&id=2407

This paper details an examination as to whether the current colour vision tests and standards for professional pilots are still appropriate for modern aviation. This is part of a study to develop a new colour vision test and establish standard norms for the chromatic sensitivity that can be used to quantify the severity of colour vision lots.
I hope it's good news...

Overflying the specific JAA country should be no problem. The only problem I can see that _might_ happen is if you use your future pilot licence on an aircraft registered in the country where you failed your medical _and_ the authority knows that you, who failed their medical, is flying an aircraft on their registry. However, as stated as of above, even if so happens it should pose no problem. In a few years time EASA might have come into effect and all might have changed by then, probably for the better in your case.

Research Paper

I recommend the above research paper to everyone. I saw the draft about a year ago and this has built upon that.

The paper will give you a good insight into the business of being a CVD and highlights the main issues at stake here.

In essence, the paper says the whole issue needs looking at and a standard test devised. It also says that colour vision is not necessarily linked to safety or the abilility of a person to fly an aircraft.

Well done City University.

FAA 1st class color blindness test worries: please don't shoot me down

Hello fellow aviators:
I do apologize If i'm starting another color blindess thread instead of posting in the designated area.
I have aquestion regarding the Isahara color blindness test they administer for 1st class medicals; I applied for a 1st class yesterday and they asked me to flip through a booklet of about 15 or so circles w/ numbers; you guys know the procedure; 2 of them i couldn't read them so i thought they were the unreadable ones they put in just to throw you off in case your color vision isn't normal; the nurse then tells me I got two numbers wrong so if she was right i'm sure those were the ones she was referring to. I've done this test before and I remember there is always one circle at the end that doesn't have a number emerge to color normal individuals, but it turns out that in this boklet all the circles contained a number. I still got the class 1; the doctor never mentioned anything abou that, but my question is if this has ever happened to any of you before and if you have to get all the samples right in order to qualify to pass w/ the color vison test or if there is some percentage you have to score above. I've taken a bunch of samples online that same day when I got home and I never managed to find that same color circle which I couldn't decipher; so my guess is that my color vision is fine; could I be wrong??

Maybe the illumination in the room was not good.

What happens if the country that denied you the initial medical certificate finds out that you passed it in a different JAA country but you didnīt mention that you had a denial with them??
Does anybody knows? and most important, can that be ammended somehow? can you ask for an ammendment of your statement?
and also, if you put that you had a denial in a JAA country before, will they pass you anyway or what procedure do they follow? Does anybody knows these??
Regards,


Do you know which examination the initial doc failed you on? Why do you think you failed the initial and why did you go for a second?

all the best

There seems to be two issues running here.

One concerns omitting information on a medical application. The second concerns not accepting or liking the results of a medical examination and as result going forum shopping until you get the result you want.

If you omit relevant information you should correct it at the earliest opportunity. Of course you cannot omit something you did not reasonably know at the time, however if you did withold relevant information you can expect undesirable consequences as a result.

If you are denied a medical and then decide to go shopping in another forum to obtain a different result, you cannot really expect the initial authority to simply say "that's fine" and accept the new result, where they have already raised a concern or made a stipulation.

To suggest that any medical deficiency is best judged by the individual themselves as to whether they are "safe" or not is simply inaccurate and irrelevant. An attempt to bypass the criteria set down by a state is probably naive and certainly a risky venture if the applicant ever intends having to make a subsequent application to that state.

I wish you well in your endeavour, and hope you are successful in resolving these difficulties, however I do feel you have been the architect of your own misfortune here and believed what you wanted to believe in order to suit your own situation.

Well finally a breakthrough. This is the study we all been waiting for and compliments to the CAA/JAA and City university. I look a bit like the australian research a few years ago only more extensive.


Is the new test already in production and if not, when will it? and what is the standard for a class 1? I am very curious.

I know some of you guys went to the city university.

thanks for the info.

steelgbr,

Could you elaborate on your experience a little.

Where and when did you take the FAA and JAA tests?
