Inverted flatspin,
Thank you for your reply.
The CAA have just received a new piece of colour vision testing equipment - the Beyne Lantern. It is currently being tested. If I can re-apply and take this test I will.
I have spoken to a colour vision specialist who basically said the same as you. The various colour vision tests measure how you are seeing things - which is fundamentally wrong.
I have two questions for you;
1. What are N registered aircraft?
2. If I fail this new test in the UK, what is the best way for a UK citizen to apply for a FAA medical and can you recommend any good flight schools?
Regards. .Ice
