Haha I didn't know much about them either until I recently I found out about tritanomaly. Every test I took growing were the red-green PIP plates. This is pretty standard because only about .01% of the population has a varying degree of this deficiency (which could be exactly why the Navy doesn't check for it either). I have been flying for six years, attained a Mulit-Engine Commercial certificate with glass cockpit experience in that time, and haven't been hindered by it.
I gotcha brother. 2 things:
1) You are an aviation medical dork
2) I had 8 years worth of 2nd and 3rd class FAA medicals prior to going to API, and NAMI was the first time I ever read less than 20/20 in one of my eyes. I won't say that is the same thing, but as a generality, they are much more strict and detailed during your initial Navy physical than any FAA doc I ever went to. There really is no point in saying this, because worrying does you no good, but I would say the same thing about this entire thread. You have no control over it......and the bottom line is that you will either 1) continue to pursue this goal and possibly be turned down at the door for some random physical DQ, 2) continue and be just fine, or 3) give up because maybe there is possibly a chance that down the road, things won't work out. Hopefully #3 isn't going to be one of the courses of action. As for #1 vs #2, there are 100000 things in addition to having a potentially disqualifying medical condition that could prevent you from getting your wings. If you worry about all of them, you are going to die of a stroke. Worry about the things you have control over, and see what the future holds for you, at least if you want to do this. I remember what it was like, the not knowing and the variables, but it's all just wasted energy in the end. Either you are going to pass your NAMI physical in a year or two, or you aren't. There is not going to be any changing the system, there isn't anything you can do to make any problem with your color vision go away, and it will either be ok or it won't.
