i have a color diffency but have 20/20 visoin but still can see red and green can i still fly?

Answer 1

If you can pass the dot tests (where they show you an array of dots, and color differences will reveal some hidden number, letter, etc.) then you will have no problem. If that doesn't work, then you have a couple of options (In the U.S.A. anyway...)

You can get a statement of demonstrated ability (SODA) by showing an inspector that you can identify the necessary colors for flight. I don't know what the exact criteria for the test are, but everyone I've talked to whose been through it says all they did was stand on the ramp, look up to the tower while the controller flashed a red, green, and white light. They merely had to identify each color as it was flashed. If you are able to see red and green, this should be no problem for you at all.

Your second option is to NOT attempt to get a medical certificate, and become a sport pilot. This would allow you to fly small 2-seater aircraft, with other limitations on where you can fly, the conditions in which you can fly, etc., but it would still allow you to fly.

Where you need to be careful is if you apply for a medical certificate and fail the exam, then you CANNOT qualify for sport pilot priviliges anymore. You always have to have a 3rd class medical to become a private pilot, a 2nd class to be a commercial pilot, and a first class to be an airline transport pilot. All of those medicals involve vision tests.

I would call your local Flight Standards District Office (FSDO) and inquire more about the SODA. I don't know exactly how you get it, I just know it is an option. That, to me, sounds like your best route.

Answer 2

It's "deficiency". If you pass an alternative test, you can still qualify for a first class medical. In addition to what has been mentioned, glass cockpit technology uses different colors, as well: such as "cyan", amber, white, red and possibly other colors. Again, so long as you can pass an alternate test, you are okay. There are some persons who are unable to pass the standard in-office color vision tests, but who truly have no difficulty in the field differentiating in the actual operational environment.

Answer 3

There was a guy who managed to get a commercial license (UPS or something) but then there was an accident and lawsuit and they found out he was color deficient.

says
"Color vision is essential for recognizing aircraft position lights, light-gun signals, airport beacons, approach-slope indicators, and chart symbols, especially at night"

I think private license is legal with CVD.
