Yes, unbelievable, although in Europe I'm unfit to fly, I can be a pilot in Brazilian airlines with ANY limitations.
Being portuguese its easy for me to speak the language and to migrate but is that what I want? NO!
I'm Portuguese, I want to fly in Europe, where I live and where my family is.
In Brazil, the exam is performed with Ishihara, of course and, if you fail, you get 6 colored paper strips (brown, white, red, pink, strong green, yellow). I've easily passed.
The question is not to prove if you're a Daltonic but weather you're able to perform pilot activities and identify on field colors, not some old-dated 40 years old exams which equipment that they're still paying for.
