It's been addressed before in the great scheme of things to go to a dual-track system in the AF similar to the Brits, Aussies, Germans, etc. I did a bunch of research on it down at Maxwell and the Air College library. Drove up for the weekend when I was scrambling to do my mandatory masters degree. Quite a few papers on it and the Warrant Officer program had been written by Air War College, ACSC and Army CGSC students over the years.
Everyone starts out the same as it works now, but at the 7-year mark you make a decision whether to aspire to be the General-type or if you just want to fly. By then, most will know a bit about the way things work in the AF and the bosses know what kind of officer/leader you'll likely turn out to be. Only about 35% of the corps is allowed to go "Specialist Aircrew" (to use the Brit term) after a good look at their aviation skills, work ethic, good-old boy check (important to know if you can play well with others), etc. The rest of the flyers/officers slog it out as usual in the big blue AF.
The SpecAircrew status slows down their promotion capability...usually only a few making O-4 and only a very, very, very few making O-5. But, they become extrememly good at their flying job, and go between the various ops squadrons and the training side of the house. But, as they develop their aviation skills, their flight pay goes up annually...so they can become fairly well compensated over the years. And the squadrons have top-notch folks in the important positions that the commander can look to for guidance and expertise. There's less people competing for school slots (helping those who want them), less numbers to move PCS every 2 1/2 years (saving money), less OPR's to write (they have a place on their annual flight eval paperwork that says if they meet/maintain Officer standards or not).
At the 14-year point, there's a chance for a crossover. Some SpecAircrew who thought that flying was all they ever wanted may have lost thier appetite for it and want to persue the higher ranks. And those who thought they wanted to be a General may have found out that they're a whole lot better at flying than the politics and meat-grinder of command and staff work. Not many swap over, but there is the chance. There's a lot more detail than this, but it gives you the idea.
It's not a bad system. You look at the winners and high scorers at a lot of the Gunsmokes and Airlift Rodeos and other flying competitions of the past couple of decades and it was the Guard/Reserve guys (closest version of the SpecAircrew I can see in our AF) that were continually taking the Blue ribbon. Flying for a living (versus being a rent-a-crowd for the commander or blood drive officer) tended to make them pretty good at their craft.
Just food for thought...maybe you guys who are still active duty can float it across the FORM 1 suggestion box and see if you can get an answer from the higher ups...good luck.
