Color vision
GiJoe,
My son just passed his 1st class medical but struggled a bit with the Ishihara and took a lantern test.
In your message, it sounds like it is an established practice that once a color vision test has been passed, no further tests of color vision will be required at renewals etc.
This would be a great comfort for my son, who is afraid that he could invest a big chunk of time and money in a career that could be taken away from him by a cranky AME
Could you provide a little more info on your sources of info?
Thanks in advance,
dennis
