What can I do to make sure I get accepted to become an aviation warrant officer?

First off, you're on the right track. Seeking info from those of us who have been there is an excellent start. I've been out of the Army for awhile now but find your way over to the airfield and introduce yourself to the aviation warrants there. Just like you did here, tell them your goals and seek their advice. If things are still the same, you're going to need a senior warrant officer or field grade officer recommendation for your selection packag. Go over to personnel and ask to visit the warrant officer there as well. He or she can help guide you on the requirements for putting together your packet.

if selected you will enlist just to go thur basic and be sent to Fort Rucker for Warrant officer candidate school, basic course and flight school which pending on aircraft is a.two year process

being a recent graduate of WOCS i did see a 7 week class that consisted of "street to seat" high school kids. pretty much 18 to 20 year olds with no army experience and their job is to just fly. Give me your email and i can shoot a message to peer of mine who i graduated with. He ended up recruiting a high school kid that turned out to be in the junior class below us.
