Supervisors in the FAA are controllers who have moved up. I, along with most of the VRA guys on here have probably worked with a lot of AOF officers both in the RAPCON/Tower and "across the street". Don't expect to get out of the AF and slide right into a supervisor spot with the FAA. It doesn't work like that. Your best hope is to actually get a CTO or a RAPC while you doing your officer training in the AOF. I know several I have worked with would work at BOPS, get flight data in tower, then come over to the RAPCON and get CD, then we'd never see them again. If you do that, you'll never work for the FAA as a controller. Get checked out the right way, or at least find somebody willing to pencil whip you some ratings (which happens a lot with AOF officers---especially hot young ones
).
Basically, you aren't going to be anymore qualified to be a supervisor in the FAA than I will (I was a line controller and WS), and that's only if you get rated. Get some signatures on that pink card or a CTO!
O yeah, might get a little better response if you put this in the VRA section. Good luck!
