If you already have a Class 1, and have passed the Lantern Test at the CAA then as far as the CAA are concerned you are fit to fly.
However, (as I understand it) if you fail those STUPID plates at the BA medical...then BA don't have the facility to perform the H.W. Lantern Test in house. As to what they will do, I haven't got a clue......sorry!
However, if you have passed the H.W.Test..then let them know and take some documentation to support it.
If all else fails, do what I am going to do......Piss off to America, where colour perception is not a major issue.
However, on a final note however, be warned. In the UK, for those who are colour deficient, there are only TWO tests for a Class 1;
The Ishihara Plates & the Holmes Wright Lantern test. There are NO other alternatives.....fail both of these and it's curtains!And don't be fooled by anyone else telling you otherwise
If you want anymore info.....please feel free to E-Mail me, as I can provide some additional advice, especially in respect of the US system.
Kind regards, & good luck.
