Colour Vision Demonstrated Ability

[inverted flatspin]

Here is a link to the Irish Aviation Authority (a JAA member) which outlines a process whereby a person may appeal a medical denial. It is written in general terms but could apply to Colour Vision Deficency.
http://www.iaa.ie/aic/4-98.pdf

The most interesting paragraph is 3.1

It mentions the possibility of Demonstrated Ability and a medical flight test.

Also in section 4. it details the relevant standards to be applied ie JAA medical standards or ICAO standards as applicable.

The JAA standards are well known, Ishihara or holmes wright or nothing but the ICAO standards are simply the ability to percieve Aviation Signal RED, GREEN and WHITE. This could leave the door open for the signal light gun test which I believe was available in Ireland before the JAA came along.

At the moment it is impossible to get a straight answer fromthe IAA as they are going through the switch to JAR's and are non commital on the final outcome.

But it does offer some hope for us CVD's out there.

I will be watching for any future developments.

Interesting, I can see a problem though, if they were to give you a class one based on a SODA test as the US and Australia do, when it comes to the 5 yearly extended opthalmic exam required by JAR would you lose the medical if you failed the Ishihara and Holmes-Wright test?. When it came to the 5 year period, they would be on JAR regs and may not allow the SODA test anymore.

Here it is from the horses mouth.

The JAA

It looks like The Irish Aviation Authority Aligned itself with the JAA in 1998 on this issue.

The sustance of both regs is the same, therefore I believe that they are equivalent.

The JAA mentions "medical flight test"

It also says that they will be looking for proof of an equivalent level of safety.

Such proof is readily available for the signal light gun test. The FAA have been doing this for years (maybee as many as 50) and to date not one single accident has been attributed to a pilot with a SODA mixing up colours.

It looks like it is up to someone to request this review. Alas I live in the US and have no immediate plans to move home but come on lads it looks like the door is really open here.
