M Maybe I can say we are lucky in the Netherlands then.
We have got a few AMC's and they all got a different colourvision test.
It is also possible to do the test as much as you want but the say you didnt pass the first time so it is almost certain that you wont pass this time either.
we got:
www.aviationmedical.com
they got the anomaloscoop test in Maarssen(Utrecht)
We also got:
www.alc-srv.com
they got the lantern (the little flashing dots red, orange, yellow, blue, green)
And the last one:
www.aeromed.nl
The got the old original test. I believe the same test as on gatwick.
the vertical green, red and white test
I believe you can test yourself at all 3 AMC's. If you pass it is great and if you dont pass ask if they will destroy the result papers.
The tests costs about 40 to 60 euro's (30 pound)
And JAA is JAA and it is possible to do only this test. It is valid in england too.
