I am 45 years old and still remember how devastated I was, when the doctor told me that I am not fit for flying, due to color-blindness.
I was 16 years old at that time, going for glider PL
However, life goes on, even without being a pilot and the irony of my life wanted, that professionally I deal now with ships and just fly the planes as passenger... And I am still a happy and content person!!!
However, color blindness: I personally am red-green blind.
This does not mean, that I cannot distinguish any colors at all and that I would see the world in black-white.
But before I elaborate further I want to make a technical distinction between additive color-mixing and subtractive color-mixing.
This, at least for persons who have inherited their color-blindness as a genetic defect from the father of their mother (same heredity as haemophiliacs), makes a great difference:
At least according to my own experience it is no problem to distinguish between ANY color, when it is emitted from a white source of light and is then filtered, for example, by a green filter. This is the part of the additive color mixing.
However, when you have a green piece of paper, onto which white (sun-) light is shining, then, depending on the intensity of the light and the kind of green I begin to have severe trouble. - An example of subtractive color mixing.
On top of that comes, that for red-green color blindness there can be dominance of green over red:
The example that the flight-doctor gave to me at the time was, that I might have to land outside of the glider-range on some green meadow, which I had chosen from the air. Only when in the final approach to the meadow, just a few feet above the ground, I would crash into a red-tiled barn that was right in my path.
A very extreme example, I know, but in easier words, a red dot within a green field is overlooked by me, because the green color is dominant over the red color in my reception.
Now, even though I am also very unhappy that I am banned from the cockpit as an active pilot as well as glider-pilot, parachuting etc., I accept this ban because I believe that someone with this kind of color blindness poses a threat to himself and everybody around him. The problem for such a person might perhaps not be so much the environment of the cockpit, but rather when this person has to ground-navigate in visual conditions. Something that is not only exclusive for PPL in VFR, but could also happen to any other pilot who is forced by some untoward circumstances to fly visually.
When you think about it, the earth, as seen from above (pilotÂ´s view) is a great variety of greens and browns and reds, the brown tones being mixtures of green and red. This will of course make life very difficult for a pilot who has at least "my" kind of color blindness.
Zksik, take it easy, in the long run you will not loose. Be sure about it. Just as a small beacon of hope: For me things lightened up a few years ago, when two things happened:
I became a very engaged simulation-pilot, flying an MD
-83 (but not Microsoft!) and a short while later I encountered a former school-mate who is now PPL and sometimes takes me along in his Piper Arrow and except for taking off and landing lets me do the flying (under his supervision, of course!). Believe me, this really gave me the kicks!
Wishing you the best,
