Facility lists usually go up through 9s for the most part for us prior guys If you’re at certain facility’s, usually the top 5 radar (at least Air Force wise) expect 7,8,9s or the rare 10/11 if you have eglin or a combo of those mentioned above. If you’re tower only then yeah there’s a chance with multiple tower ratings, usually 3+ that you’ll end up on that same 7/8/9 but usually you get the 4/5/6 list with maybe a 7 thrown in there. It’s all based off traffic count at facility and then years experience but that’s less important than traffic count/complexity. This is all from the head honcho that runs the assignment program at the ATO office. I was also told if you’re in the 7/8/9 group to expect to get one of your top 3. If you fall in the 4/5/6/7 group then it’s a crap shoot. They try their best for the smaller facility lists but they can go a lot farther down the dream sheet than the higher ones.
