The initial test for color vision is similar to the previous standards and utilizes the color plates. If you cannot read the required plates the limitation would be placed on your medial certificate: NOT VALID FOR NIGHT FLYING OR BY COLOR SIGNAL CONTROL. What has changed is the process for permanently removing this color vision limitation.
Class Three Medical Certificates
The test should be taken during the day, and if you pass there would be no color vision limitation and you would receive a Letter of Evidence (LOE) applicable to Class 3 privileges. If you fail you can take the test at night and if you pass this the certificate limitation would be: NOT VALID FOR FLIGHT DURING DAYLIGHT HOURS BY COLOR SIGNAL CONTROL
One and Two Medical Certificates
Applicants who take and pass both the daytime OCVT and the color vision MFT would have no color vision limitation and you would receive a LOE applicable for all classes. Applicants who can only pass the daytime OCVT will be given an LOE valid only for third-class medical certificate
The FAA stipulates tests can only be taken once and if you
fail a test you cannot have a color vision limitation removed at a future date
by passing one of the approved color plate tests.
The Guide for Aviation Medical Examiners has a flowchart summarizing the above and a full discussion of the color vision standards is in Part 52 of the guide. If you are an ATCS your color vision evaluations are different from those of pilots and refer to the ATCS requirements which are also in the guide
