K, I'm on your side, but... Sounds like you have a very significant exotropia (the misalignment of your eyes) with monofixation syndrome. The same condition I have, but much more severe. The MFS is where the brain ignores the non-dominant eye's signal. The exotropia is fixable with the right prism glasses, and you can retrain your brain to overcome your MFS while wearing the glasses. But you'll find that when you're stressed, you'll tend to fall back into the habits your body has learned over it's life and will start dropping out the signal again.

Interesting that you point out the limitation of DP to inside a range of 30 feet. You're correct. However, that's exactly how my deficiency was discovered. I had flown the 141 and C-12 and instructed in both the Tweet and T-1. But never had to do air refueling. When I got to the C-17, AR is a required qual, but I just couldn't do it. Had some problems during the day, overcame them, but couldn't do night AR without the glasses. The tanker is about 20 ft away, it's really big, moving in an unusual perspective, and isn't like anything you've ever experienced before. And if you mess it up, at best you divert for gas, at worst you hit the other plane. Add in night, in the clouds, and 18 hours since your last night's sleep, and that adds the stress that leads to loss of the DP, even with the glasses.

Now, you're thinking, okay, how about I come in and just don't fly AR. Not an option; you can't come in on a waiver like that. You need to be assignable to anything. Also, they only have so much training time. They're not going to want to bring you in if they think you'll need extra training time for a known issue. I'm just trying to explain the rationale for why it's so much harder to get a waiver to get in than it is to get one once you're thru.

I, too, applaud your desire to serve. But you may have to settle for not being an AF pilot. I'm not saying it's impossible to get the waiver, but with a 14 degree exotropia, I'm doubtful (my exotropia was a small fraction of a degree, and I was grounded even with that). As previous posters have said, you need to find the reg, and figure out what the limits are and who's responsible for granting the waiver. And either way, start coming up with a plan B. Good luck.
