Blinkz,
Your chances of getting a re test are slim at best.Even then,you might not pass it again.
I went to City university in london,where a lady there, Theresa Squire,is doing research for the CAA. It involved doing the good old lantern test again,using other equipment that our friends on the continent use.
Even though I failed to meet to CAAs standards,I did do the city university test which they have produced.
Its designed not so much to say your colour defective,you are not safe...it asseses by how much and in which areas.Its a much better and fairer test,computer based.
I`ve got a link to it here:
http://www.city.ac.uk/avrc/colourtest.html
I was assesed and was suprised to hear my colour vision is not all that bad,very slightly red defective.
The test involves a large box which has a smaller box inside it.The smaller box moves from corner to corner diagonally,changing colour whilst you do so.You have a keypad which has four buttons in a 2 x 2 grid. If you see the box moving upwards and rightwards,you press the key in the top right hand corner of the control pad,if it moves bottom left,press the bottom left button.
The test is about as good as we can wish for really in the short term until we get an on the aerodrome assesment like the USA / Australia.
Also,I have learnt that British Airways and I also think BMI did some assesments on the A321 / B757-200 cockpits and how much colour vision comes into play. Interestingly..the results are that its not as critical as the myth we are led to believe,the A321s FMC having a multicoloured display compared to the boeing variant being a so called "issue"..and that this is not a critical issue. !!
The next part of the study is happening now by Qinetiq (formerly DERA).They are concluding the study on anything that is not based in the cockpit..ie taxiway lights,aerodrome lighting etc,assesing if a colour defective would be dangerous in this enviroment.
We should get an answer in a year or so and then perhaps a year or so after that,we`ll see the changes filter to the CAA / JAA,people being tested soley on this new test.
Also,there is always the way of the legal system if things do not turn out ,arguing that Captain America is flying his american registered 747/777 into EGLL when,using our tests,they would be considered dangerous.
I`m sure that would be a good argument and one the authories might not be able wriggle out of.
