In a non white jet ARC unit, the Full timers exist to get the part time force current in the event of a call up. There is no way anyone in the 130 world can stay NVG, Airdrop, Assault Landing, Low-level, SKE, and approach and landing current without living at their airline job and having their ARC unit in the same city. Even at that, we had guys non-current all the time in my unit.
A 6-8 day average participating part timer would be nice in every commander's perfect world but it just doesn't make sense. What are they gonna do, hand out mini-active duty activations to make guys come to work?
The idea does make some sense in our world where the focus is on undergraduate student training. We don't have enough AGRs to keep part timers current, and our active duty customer doesn't have enough IPs for that either. So you really have to stay current, meet your CT beans, and do your required number of student sorties in a quarter/half/year.
BTW I am not saying that I agree with all of our policies, just that I understand where they are coming from. I key on the word average. After 12 plus months of troughing, if I ever get a real job, I figure I could not show up for a year and still be doing 6-8 days as an average.
