Careers In Aviation For Someone Colourblind?
Just today, I took the Ishihara colour test, which I expectedly failed. However, upon taking the Farnsworth D-15, I flawlessly passed the first two tests, made one error on the third test and then flawlessly passed the fourth test. Upon taking the Holmes-Wright lantern test, I was informed of being inconsistent in determining green and white.
My question is that if I consistently demonstrated complete competency and accuracy with the Farnsworth D-15 (supposedly the alternative to the Ishihara, while the Lantern is the alternative should one fail the Farnsworth), upon which grounds will Transport Canada consider my colour vision competency? Will failing the Holmes-Wright outweigh my successes on the Farnsworth?
Thank you in advance.
