The FALANT is a series of 3 colors, red, white and green, shown in a series of 2, with one on top of the other. So you'll be looking at a red light over a green light, then the next will be a red light over a white light, ect. The lights are at a distance of 8 feet against a black background to simulate either ship or aircraft positioning lights at night and at a distance. Some applicants who are weak with the PIP plates have no problems with the FALANT, but there are just as many who have problems with the PIP plates who fail the FALANT.
The PIP plates can be difficult even for an examiner to read. I wouldn't worry about it right now. If you do the FALANT and don't pass that, then it will be an issue for the Naval Academy, but not for AF. AF will re-test you in your junior year again if you desire aviation.
