ren - What unit are you going to? The average time studs were home varied from a couple of weeks to almost a year. From what I was told...Yes, helo slots are fewer than fixed-wing...only about 4 each year for the guard. Once you start in the pipeline, (Phase I, I don’t think IFT or AMS count) you stay on active duty orders until you are done with everything, including your home seasoning. If it's a long break between pilot training bases, they'll keep you at that base (or PCS you to the next base) doing admin-type work. I was halfway done with Phase II before I got dates to Rucker...and halfway complete with Rucker before I got my dates for Kirtland. Basically, you'll just have to be patient.
Rainman...I don't know exactly why only 90 days. We come out of Kirtland (equiv to FTU) fully MQT. It's a 6+ month long course so they throw a lot at students. Studs start tac training (very basic) while at Rucker now (NVGs and tac form) too. So, maybe that's why only 90 days home seasoning to get LMQT (slings, day water, night water, etc.). It's hard to get/stay proficient with only 90 days. Plus, there’s only one place with a Pavehawk sim, so we can’t even practice at our home unit.
