Yes.I think a campaign should be started against the CAA for discrimination against pilots with a colour difficiency.I have over 2000 hrs on a PPL/IR and cannot progress further because of their intransigent attitude.I am allowed to fly on airways in zero visibility down to 250 feet on the ILS yet denied a CLP/ATPL.In U.S.A.or Australia I would have a class one but in the U.K. zilch.
