ATCO colour vision test
I am applying to become an ATCO and have a question about the ATCO version of the JAR CLass 1 medical for eyesight....
For the JAR Class 1 medical the CAA says that you must pass the Ishihara test, and if you can't do that then you must pass an approved lantern test.
For my own peace of mind I have taken the Ishihara test locally and will take a lantern test next week. I can get most of the questions right in the Ishihara but do have difficulty with some. As I suspect that I failed an RAF medical on colour vision 12 years ago, I am a little anxious.
My question is,
Are the rules for colour vision for ATCO and pilots EXACTLY the same, or are they slightly less strict for ATCO? (The CAA says that the eyesight medical for ATCO "generally" follows the JAR Class 1")
I don't see any posts on the forum colour blind thread specifically about ATC so I hope that someone can help here.
Thanks
