Hello everyone,

Apologies if this has been covered before, but 'Search' didn't return any results. Firstly, I'm having difficulty finding the Belgian adaptation of the JAR-FCL standards. Could someone please either provide a link to their specifications/limits, or write the specifications/limits here?


Secondly, my situation is as follows: Simply put, I am within the UK CAA initial limits (+5/-6) but suppose I were to fall outside of the Belgium limits. Presuming that I pass the UK CAA Class 1 medical, would I be able to renew or (pardon my ignorance here) convert the UK medical to a Belgian Class 1?

Thanks in advance,

Dear Sergs,

I don't Know Belgian limits, but unfortunately I must inform that CAA initial limits are +5/-6, not -8!


Bye!

Thumbs up

ACIDO,

Thanks for the post. You're right, ofcourse, it is -6. I read the entire 22 pages before making my post and I think that's how it shows itself.

Regards

Sergs

I think because my post got moved here, it must've been skipped. Anyways, I'll repeat myself:

Thanks.

can you obtain a class 1 medical if you are just over the -6.00 limit or is it if you are over by any amount you will fail??

hello backtrack,

ive found vision training exercises helpful for my myopia....your son may want to see if they help before trying surgery.

my myopia was -5.25 eight weeks ago. A sight test this week showed it's -4.75.

The two things that have helped me the most have been leaving my glasses/contacts off as much as possible, and wearing plus lenses (+1.5) while doing near work.

I think my progress has been pretty decent considering I have to do a fair bit of reading every day, and have to wear contacts/glasses for hours at a stretch when Im at work (im a medical student).

hope this helps. good luck!

It's in London - http://www.city.ac.uk/optometry/

Personally I found the Farnsworth much easier than the lanterns used in JAA-land, so it might be a decent option for you!

Just wanted to add a few things from experience here.

My perscription is .25 over, and the guys at gatwick asked for my perscriptions for five years, then asked me to go get two more. They then said its 50/50, but if i can read the 20/20 line with my specs on then i will be ok.

So advice from that is, if you are a little over the limits, but can read 20/20 with correction then its worth a shot, if you cant read 20/20, then sorry to say, its not going to happen, thats what they told me.

Another thing, i have read loads about improving vision using natrual techniques.

This is not 100% rubbish to a degree. The techniques actually help the muscles of the eye, and in turn help you focus and see better, however, they dont corrent vision in the true sense.

Its possible that if i trainined my eyes to focus better then i could improve upto 1diopter on the eye test, an optician told me this, and another one reluctantly back him up, but said its a long shot.

The only way to truely know is to take the test, and if you pass you pass, and then that great. If you fail, then thats just the way it is, life goes on, and you;ll not spend the rest of you days asking what if?

With regards to the last thread, I also got an improvement leaving my specs off for a week, i went from +5.25 to +4.75, which is very similar to yours.

I considered the laser too, however, there is a 30% chance i will get 20/20 vision, even if i can see now 20/20 corrected they informed me at my consultation that there is a good chance i will loose the ability to see 20/20 corrected or uncorrected, which is why i said no way, as the CAA told me that 20/20 corrected is a must, and i will take no chances.

The last thing, at my consultation they told me about an astigmatism reduction surgery, where they make two cuts and this can reduce astigmatism, which in turn, usually correct vision by a small ammount. However, since its a small ammount i need, i am looking into this very serious.

For the guyes that are long sighted, there are new ways now to improve your vision using a lens when you sleep, my optician sells them but tells me they are only useful for long sighted people, dont know any more about this as i am short sighted.

Hi, I'm in the process of researching for my flying training in Australia. I may be calling up an AME in Australia within the next few days as I have astig of 1.0 in both eyes and myopia of 4.0 also in both eyes. This may be of interest to you: http://www.casa.gov.au/manuals/regulate/dame/index.htm

Hey guys,

Ok, have been browsing around on this site and there seems to be a lot of helpful info being shared, so hope i'll be able to get something back for this.

OK, like so many of you... im really passionate about being a pilot, but because of my eyesight i dont think i can get a JAR Class 1. Funnily enough, after looking at the criteria i believe i can get a transport canada or FAA licence, but since im european (irish) i'd like to try whatever i can to get a JAR one.

OK, the result for my recent eyetest (2 weeks ago) are as follows:

-small to moderate right convergent strabismus which on occasion is alternating (right esotropia)

- bilateral inferior obliques over action in a V pattern

-visual acuity or 6/24 in the right and 6/6 in the left. Weak vision in the right is due to a myopia and astigmatism (-3.5 ds with a -075 cyl axis 165).

- a correction improves right vision to 6/5 part

-1 dioptre of myotropic astigmatism in the left eye, with correction, left vision improves to 6/5.

-Generally eyes are healthy. Ichihara colour vision test normal, as is intraoccular pressure.

OK, so would anybody be able to give me some advice/help on this one or is anyone in a similar situation?

Keeping in mind that since i live in Ireland (the rip off republic) and its actually cheaper to fly over and back to the UK to get a class 1 medical, its an option i'd consider, so any JAR info would be appreciated.

Thanks!

steve

2close,

I m from Asia, where its national carrier is one of the leading airline in the world.. " )

anyway, yes, it is quite an old equipment and I was not able to find out much about the colour used in the test...it was not so straight forward as for some part of the test, it has a filter that mask the colour as though you are seeing through a layer of dust and mist..

nevertheless, i was still able to pass the test by identify the colours correctly.. hope that, soon i will be able to fulfilled my childhood dreams..and for the rest, not to give up..

cheers,

Good stuff Cookie,


Just don't build your hopes on being able to pass one of the JAA tests on the basis of passing the E-G test.

Sticking with your home national carrier sounds like a good option.

Happy flying,

Hi Tel,

My German is fine but that is one really difficult to understand accent; only the second time I've tried Swiss!!.

All it says, though, is along the lines of "This is a recorded message for Augenpraxis..... The office hours are 9 - 11 in the morning and 12 - 4 in the afternoon. The emergency number is yada yada yada". I hung up then to keep the cost down.

I suggest you give them a call between 11 - 3 UK time.

HTH

Message For Windforce

I'm a little confused about the possibilty of obtaining a night qualification as a colour retard. My class 2 restricts me to day only.

I have been advised by an Instructor that I cannot obtain a night qualification because I cannot comply with the requirement ‘to complete 5 take offs and full stop landings at night as PIC of aeroplanes’ as my licence restricts me to day only and therefore cannot be PIC at night. Further the entry requirement for a CPL course is worded slightly differently, it requires ‘5 SOLO take offs and full stop landings’ which again seems to be contrary to my licence. I have had this view confirmed by the CAA. They have advised that if I want a CPL (restricted to day only) that they will agree a deviation from the requirments and provide a letter to give to the training organisation so that I can undertake the course-but no night qualification.

So my question is-as usual -who the hell is right

In this case the CAA because they unfortunately think they own the air around us.

But my advice would be to be very careful given the EASA chaos that is about to descend upon us. Many others have written here how they think that all of the deviations issued by the CAA for the like of us will be worthless once EASA is in charge.

Stick the instructor in the RH seat as a safety pilot, then fly your circuits and log P1. That's how many people have done it, and the CAA have happily issued their night qual.

The instructor who told you otherwise is incorrect (although the CAA do have a habit of making it up as they go along sometimes, so perhaps he's not entirely to blame!).

Thank you 2close

Thanks 2close for the translation, you are truly a star. I thought I was going to have to go to night school first to get passed the JAA

just a quick reply for anyone who has been in a similar condition to mine...

a few days ago i got my eyes checked by an aeromedical examiner, however, i wasn't given a "yes" or a "no". i was referred on to the aeromedical center in Dublin for the following reason:

basically, my visual acuity is fine, but the main problem is with my stereopsis and binocular vision. The good news is, that my brain hasn't entirely suppressed the input from the weaker eye, as would normally be the case for most people over the age of 20 with the similar condition, however, the problem being that my eyes dont fixate on one particular point, hence the stereopsis problems.

So, its off to dublin i go for a referral, and get the aeromedical examiners opinion. If this fails at achieving the requirements, im gonna have to look at getting my weaker eye straightened, and hopefully try to recover some of the stereopsis this way.

for completeness sake, the rules in the Jar-FCL 3 is

"An applicant with significant defects of
binocular vision shall be assessed as unfit. There is
no stereoscopic test requirement "
"Monocularity entails unfitness for a Class 1 certificate."

"(e) An applicant with imbalance of the ocular
muscles (heterophorias) exceeding (when measured
with usual correction, if prescribed):

2·0 prism dioptres in hyperphoria at 6 metres,
10·0 prism dioptres in esophoria at 6 metres,
8·0 prism dioptres in exophoria at 6 metres;
and 1·0 prism dioptre in hyperphoria at 33 cms,
6·0 prism dioptres in esophoria at 33 cms,
12·0 prism dioptres in exophoria at 33 cms

shall be assessed as unfit.

If the fusional reserves are sufficient to prevent asthenopia and
diplopia the AMS may consider a fit assessment

For Heterophorias: The applicant/certificate holder shall be reviewed by an ophthalmologist acceptable to the AMS. The fusional reserves shall be tested using a method acceptable to the AMS (e.g. Goldman Red/Green binocular fusion test)."


I suppose any input from people in similar cases would be great. thanks!

Anyone else get a letter from City about further red/green CVD research? They say they'll throw me a tenner and travel expenses for my trouble. Wonder if that stretches to 120L of Avgas
