Class 1 Renewals and colour perception
I have had a class 1 medical now for 2 years and recently had it revalidated in Spain.. during the examination the person doing the examination pulls out the Ishihara book and starts asking me to read off the numbers on the pages.. During my Initial class 1 at Gatwick, I struggled with this and ended up doing the Holmes-Wright Lantern test which i passed no problem and thankfully was issued with a new class 1 medical.. I have had it revalidated by an AME in the Uk but they didn't conduct a colour perception test, however the woman in spain was sort of helping me to read the colours by asking me can you see '8' or '5' etc... and informed me if i couldn't see them i would fail the renewal, is this the case that you can fail a revalidation based on colour perception....
