Neeonlizard brings up some excellent points. ERAU is on my DS’s list of universities he will apply to this fall. I do contract work at ERAU and other universities in the southeast and yes ERAU is expensive. Current out of state estimated cost is $58,189 per year. That number include tuition & fees, room & dining plan, and books (estimated). That number is for Non Flight Undergraduate students. I have found that some state/public schools post only tuition rates, so do your research.
ERAU is a great school. I know two ERAU Daytona Aeronautical Science alumni who are professional pilots. One is a 737 Captain for a major carrier the other is a captain for a corporate charter company. ERAU, University of North Dakota, Perdue University, Middle Tennessee State, etc. are great universities to become a professional pilot. As others have stated above going to ERAU, UND, etc. for Aeronautical Science (flight training) then entering military aviation and doing the same thing defeats the purpose of ERAU, UND, etc. Aeronautical Science.
As for military aviation you should understand there are NO guarantees in military aviation. Do not self eliminate, go until someone in authority tells you no. Hopefully that will not happen to you but things can go sideways. I have known Air Force & Navy officers that have been selected for pilot/aviator and not passed the physical at Wright-Patterson/Pensacola. The DoDMERB physical is not the same as a USAF/USN/USCG flight physical. There was a post on this forum about a cadet/mid that was six weeks away from commissioning/graduating with a pilot/aviator slot and got popped on a drug test and now has to pay back the scholarship with enlisted time. In these 2 examples one is out of your control the other is result of bad judgement. The point here is to have a plan B with the military should the pilot/aviator option not work out.
As for becoming a pilot/aviator from the enlisted side I agree with others on this thread. Is it possible, yes, but the numbers are very low, think single digits closer to 2-3% than 9%. In the Air Force, Navy/USMC, USCG you still need a 4 year degree. The Army is the best option, IMHO, from the enlisted side. A short example of how that works goes like this: Enlist with a MOS in the aviation orbit (aviation power plant technician, avionics technician, etc.); make E-5 (may be a old requirement), be an outstanding soldier, apply for the Warrant Officer Aviation program. The Army has a “High School to Flight School” program but the success rate is low. I would ask a lot of questions about that one.
Back to the college subject I would look at ROTC programs at universities you can attend. I can tell you the NROTC program at ERAU DB has had little to no College Programmer (Non Scholarship) slots the last few years.
Best of luck to you!
