Scroll down to the "Army Jobs" section and look for "Transportation & Aviation" Once in there look for the thread: 'Warrant Officer Flight Training - ask your questions here.' It has over a thousand posts and is 72 pages last I looked.

If you can't find an answer there, PM and I'll try to give you a steer.

Good Luck.
