eye sight Hyperphoria

Help!

Have been poking around on CAA website, for JAR Class1 it states under eye function that

in excess of 12^ exo and 8^eso or 1^hyperphoria at 33cm will require further evaluation by en eye specialist at Gatwick

I am approx 3^hyperphoria (slightly over). Obviously i will need further examination, but does anyone know what the cut off would be? Should i just give up now???

Cheers

FAA medical

I recently spoke to an aviation medical examiner who said that although my eyesight was out of limits through the CAA on account of my astigmatism (CYL), there is a possibility it would pass an FAA medical allowing me to fly in the USA. Any pilots under the wing of the FAA shine any light on it? Prescription:

R: +0.75 SPH -4.50 CYL 5 Axis
L: +2.25 SPH -1.50 CYL 1.70 Axis

They are extremely irritating and more so if you are young and/or have excellent vision.
An eye test normally shows that your eyesight is just the same as before and you need not worry (it did with me). They take the pressure of the fluid inside the eyeball as part of a thourough test (i forget what this is called, ocular pressure??)

Hi,
For a FAA Class I or a Class II medical you only have to correct 20/20.
You may want to check what the CAA wants for renewel because if you have a FAA Class I and apply for a CAA/JAA Class I they use the renewal limits. Your astigmatism may be out offlimits for renewal but check it out.
Best of Luck.
PS- Don't lose your dreams.

east sider, the FAA light signal test has a 95% pass rate. This probably means that all trichromates will pass. You have to have faith in yourself.

I DO understand the family ties. I am in much of a same situation - 10 year relationship and an elderley mother, now on her own after my father died a few years ago. However there IS work on an FAA licence in this country and very kind people have messaged me about contract work overseas - like one month on and one month off - gives you great time to spend with love ones and fly - and get a good pay day!!

It is never going to be easy. Even without CVD professional aviation requires dedication and is a long uphill ride, even more so for the likes of us.

As for other JAA states - why not have a few days holiday with your other half and take a few hours off to do the tests.

I have had a message from this forum from someone who it took 5 years to pass a test - he recons he failed everything going, but passed in the end and got an unrestricted class 1 - now that is dedication.

In the end, none of us can tell you what you should do, only you can decide that, you must go with what is right for you. Just remember we are all behind you. I know how it feels to fail the tests. I have been described as moderate deuteranomaly - probably worse than you, but I have the FAA letter of evidance to fall back on and that gives me hope.

All the best mate you are not alone in your feelings.

East_ sider. You mention Australia and USA as moves and possible aviation career paths at one stage.

Unfortunately, I suspect with or without color vision, a UK citizen would have little chance to fly professionally in Australia. I'd imagine the same would go for the USA. You would need to research the Department of Immigration's identified job skills shortfall and if aviation is identified (which it isn't) the subsequent requirements and criteria for resident status to obtain work. About two to three years from the time of entry to the country.

Nevertheless, good luck with your color vision tests.

Ok, I went to see an opthamologist here in Dubai with a fistfull of papers and forms showing the CAA requirements. My vision is dam near perfect apart from officially 2 diopters of hyperphoria (Caa limit is 1).

I called Gatwick and faxed through the completed form. The Opthamologist there looked at the form and called me back within ten minutes, which i thought was impressive!!!! They said that i should definitely come for the medical as the 2 diopters doesn't really matter, they want to test and see that i can cope with it. Any ideas what this means or what they will be looking for????? (they could ask me, I'll tell them i cope fine ). Will i just have to wait in limbo now until i go over to the UK in July? Very frustrating!

anisometropia

I am just wondering if anyone suffers from this. It is the condition where there is a difference in myopia in both eyes.

I really hate having this as I might not be able to get a class 1.

my presription is:

L -0.75 -0.25 180
R -2.25 -2.00 177
.
As you can see my right eye is letting me down. I see fine with my left eye and I dont really need my glasses.

The max difference is 2 at the moment with the CAA. I was just wondering, if my much better eye was knocked down, then I would get a class 1! that means i would not be able to see without glasses but it would mean i would get a class 1. so weird!

Technically it is outside published limits, but if you haven't already done so, ask to speak to the UK CAA's optometrist Mr. Adrian Chorley as there is sometimes a little more flexibility in the system than may first appear. If you have already spoken to the CAA (recently)then ignore this post.

Thanks Hawk and TelBoy, I might be taking a holiday in the US this Autumn so I will try and take the FAA test then. Presumably there’s information on this thread on how to go about finding a place and booking in?

to add further

So from what I've read on the net the Anomaloscope should be adjusted yourself. Not by the Optician

east sider. From what I understand to get an FAA Light Signal Test you need to have a restricted medical (FAA of course). At any time during your training you can then take the signal test.

I'm not sure how it goes with the US visa and TSA now if you were there on holiday. I did mine with a M1 visa (TSA did not exist then) when I was doing my PPL in Florida (FAA PPL of course).

It might be worth phoning the FAA - remember the time difference between us and the US, they are very helpful. Also call the US embassy to see if you would need a student visa.

All the best - glad to see you are still fighting.

My latest eye exam.

I know that there is a VISION THREAD...but to avoid the usual suggestions from wannabes I was hoping that some of the vision experts can have a look at it for me.

My amblyopia has not affected my FAA licence (I have a class 1) - what is the big deal about me flying an identical (but non N-registered plane in Europe)

Flyin Dutch etc or any others in this area....should I go to the CAA with this, or should I hang back until I have a 1000 hours ME time??

Am also thinking about shelling out 2000 USD for a NeuroVision treatment package........

Results were:

VA right eye:
Dist: 6/24-2
Near: N18

VA left eye:
Dist: 6/6
Near: N5

Right Eye:
Sphere: +2.75
Cyl: -0.50
Axis: 130.0

Left Eye:
Sphere: +0.50
Cyl: -0.25
Axis: 70.0

Unaided Vision:
Right: 6/30-1
Left: 6/6

Vision is 6/6 with both eyes open

Interoccular pressure:

Right 15.0
Left: 15.7

BVD: 12.0

Binocular Vision: Abnormal (no measurable stereoacuity in TNO Test due to amblyopia)
Colour Vision: Normal
Visual Fields: Normal
Slit Lamp Examination: Normal
Occular Motility: Normal
Fundus: Normal

No other abnormalities.

(Optician states Rx not required)

Just writting a love letter to the CAA. Quick question, do FAA CVD pilots fly widebody commercial aircraft into UK aerodromes? Ta.

Yup, every day of your life because they have no restrictions placed on them if they have a FAA licence and are flying an n reg aircraft...even into EGLL.

The ice has just cracked..

wf, I'm behind you. I also wish to do such a thing when I get my FAA CPL - probably next year.

I think if you have such PROOF ie another ICAO state licence and experience, that it is a good case for the DDA.

Only a word of caution. The UK CAA is a "bit" more relaxed than the JAA and after all it is the JAA standards they are administering. I can see if the s hits the fan, then they will do something like the Australians and we will have a UK CPL - only good for UK airspace (a BIG NPPL). In reality still VERY limited.

I feel that the JAA should be lobbied on this.

Any how good luck and keep us all informed. I will.

I agree on lobbying but I think the target has to be the UK CAA and the UK DfT with a view to having the JAA implement new rules but also the argument must be made clear to EASA.

The JAA is not a regulatory body and has no legal clout whatsoever. You cannot take the JAA to court - you would have to take legal action against individual member states.

Whilst member states quote JAA this and JAA that these are merely agreed standards and the actual legal entity is the governmental department responsible for transportation, in the UK this being the Department for Transport. The CAA (a public corporation) is merely the watchdog for the DfT.

The UK CAA, if it agreed that the argument was valid, would have to put the matter before the JAA for review. If the JAA review board agreed and the rules were changed then this would be a new standard applicable to all member states........sort of.......any member state can file a deviation but that deviation is then only valid in that member state's airspace (e.g. you can fly commercially in the UK up to the age of 65 but not through French airspace where the limit is 60. You can fly commercially anywhere in EU where one member of the flight crew has an OML on his/her medical certificate but in the UK both members can have OMLs.)

When EASA comes into full swing the goalposts will move, their rules will be enshrined in EU law and it wil be a balls-ache of a job to get things changed. Now is the time.

Personally I would be happy with flying regional TPs in the UK only - it would be ideal for me - I'm not and never have been in the slightest bit interested in flying the big airliners but the Dash 8 etc, that sounds like fun and challenging. In the meantime I'll stick to instructing.
