I can tell you a thing or two about height waivers, since I'm on one.
I went the off-the-street OTS route and did my FCI physical as a civilian while going through the application process for a pilot slot. During my FCI, the measured me 64.5" standing. Shoes off, feet together, up against a tape measure on the wall. I forget what I measured sitting, but it was good enough to pass.
After OTS, I went to Brooks and measured up 63.7" standing. Shoes off, feet apart, away from the wall using their super-duper-body-measuring-device. They measured me twice, but unfortunately I was not able to magically gain .3". I passed everything else that day (sitting height included), but was DQ'd for .3". To be honest, I really wasn't worried about my height going into Brooks. It was literally the last thing on my mind. I was worried about them finding a heart or vision problem. I never imagined that my height would vary almost a full inch from what they had measured me before in the FCI. I always knew I was *around* 64" and when I measured 64.5, I figured I was good to go. Obviously, the individual who measured me during my FCI didn't do such an accurate job.
Because I failed the height requirements, they took additional measurements on me (reach length, but to knee length, etc...). This had given me some hope because I figured; why would they take additional measurements if they were DQ'ing me? However, at the end of the day, I got the walk-o-shame to the office for the, "I'm sorry, but you're going to have to go to the MPF tomorrow to pick another job in the Air Force." spiel.
The staff at Brooks told me there was no such thing as a "height waiver" because it is not a medical condition. They said I would have to get an "Exception to Policy", which at the time had to go all the way up to the Chief of Staff for approval and could take up to a year to be approved. In the meantime, they wanted me to reclassify and ship off to a new base somewhere while I worked the issue.
So there I was... faced with having to reclassify to a new career field so I could start working up through a chain of command that most likely wouldn't have given two poops about me and my flying career.
What did I do? Long story short... I raised the BS flag and basically refused to reclassify. I had spent the past 10 years of my life flying airplanes, left a civilian flying job to go to OTS and I wasn't going to give in and let them take the opportunity to go to UPT away from me because someone couldn't read a damn tape measure. I was furious. :mad: This was something that could have been avoided. Things got a tad hot that day, but I ended up being able to proceed to my UPT base and spent 6 months as a casual Lt while I worked the waiver. It was a long process and was an emotional roller coaster, but thanks to a kickass commander and the help from the flight medicine staff at the base, I was granted a cockpit fit check and subsequent waiver to fly T-1's. Overall, not a process I would want to go through again, although would if I had to.
It is my understanding, that due to this very thing getting more and more common (especially with more and more women getting UPT slots), they have streamlined the process. I hope for their sake they have.
