What is the Flight Warrant Officer application process and requirements for active duty?

Sir, I was reading a bullet in that link that stated:

All In-Service applicants must have a digitally signed letter of recommendation from an Army Aviator (CW3 to CW5) currently serving (Not Retired). In-Service Applicants may supplement (not replace) the Army Aviator (CW3-CW5) LOR with hand signed LOR's from Retired Army Aviators as desired. Active or Retired Army Aviator LOR’s for Non-In-Service applicants (WOFT) is encouraged but not required. If the unit commander or above is a field grade aviator, the aviator interview may be part of the commander's endorsement. In this case, the commander's endorsement must contain the same statement required for the aviator interview. Use a memorandum format and start with the statement I have interviewed (your name) and find (he/she) has the needed personal characteristics, motivation, physical stamina, and qualifications to be appointed a U.S. Army Reserve warrant officer and appears acceptable for selection into the WOFT program as a warrant officer candidate. Applicants from other military services may be interviewed by a field grade aviator from their branch of service if an Army aviator is not readily available. Army aviators will conduct the interviews whenever possible.

My CO is an Aviation officer. Could this mean that his recommendation/interview be a great help in getting me selected at the board?

Alexander,
If your commander a Field Grade officer? LTC or above Major and Below are staff grade officers, therefore if he is LTC by all means that will help and he may be able to assist you with locating a CW3-CW5 for the LOR that you will need, the biggest thing about becoming a Warrant at least from my perspective and I am sure that there are at least a few out there with it, I personally do not care what your commander states about you although it is required documentation, I care more about what my peers think and say about the potential candidate, if I were you I would contact one of the POC's listed in the link and ask there opinion and advice, because at the end of the day one of those gentlemen are going to be the final decision makers, I hope that helps with your question.

Thank you Sir, your insight has been extremely helpful in getting me in the right direction!

Good point sir.

Sir, I am currently working on the SIFT test. I have a 130 line score on the ASVAB. Also I am working on becoming MOSQ for 15T, so I will have a good understanding on the mechanics and component identification of a helicopter. I got a SIFT study guide and my old pre calc and calc books to practice with from college. So I am hopeful about the SIFT test. The flight physical may be hard to get right now, but I am sure with a little persistence and some help from my NCOs I could get one while I am here or on leave. For letters of recommendation I currently have a retired 2 star Marine Aviator (Cobra Pilot), a retired Marine COL and an active duty 1st LT from the Air Force. All who know me very well. I am also in the process of trying to meet with my CO in order to get a letter from him since he is a Active Duty Army Pilot. Do you think this may be a good start to the recommendation process aside from needing a Flight Warrants letter?

It is a good start for sure. Study for the SIFT and only take it when you know you are ready. When you pass you are stuck with your score forever, you can not retake it. Your passing score is the final one you get. You need a letter of recommendation from a CW3 or higher or an O4 or higher aviator. I would recommend they be Army. If you can't find one hit me up and I will see if friends I have would be willing to write one for you. Let me know how I can help you and I will. Don't quit on your dream. Read my previous post and you will do great.
