Hi Stephen
I'm currently attending Ohio State's flight program, so I can't give you too many specifics concerning ERAU. I've heard around 3.5 cumulative GPA is enough to get into ERAU, but extracurriculars and AP classes really do count just as much as GPA, so don't fret if it's a bit on the low side.
I'm sure you've heard about this already, but my advice to you, as a fellow student and a pilot with significant student loan debt, do not go to ERAU unless you can pay with cash, get a very generous scholarship or you have an arrangement with the Air Force. The cost is astronomical...over $41,000 a year. My question is what are you getting for that? You get the newest airplanes with all the toys, but that doesn't make you a better aviator. The major benefit of Daytona and Prescott isn't the school, but the year round flying weather, and you can get that by enrolling in a public college program anywhere in the South or Southwest for half the cost.
You mention a desire to go into the Air Force. Yes, ERAU has a great relationship with them, but just about every single flight program in the country also has a very active AFROTC program. And it doesn't matter what school you go to, just because you are in AFROTC doesn't mean you'll fly with the AF. I don't really know about loan forgiveness in the military, but I do know that you'll have a tough time paying for more than half of the cost of ERAU through loans...no one owes you financing for your education, so don't assume that you'll have access to adequate credit until you've actually applied for the loans!
Bottom line...I love flying, but I would never pay that much for a flying education. You can get a better deal almost anywhere else in the country. Talk to you high school counselor about aviation programs in your state, paying for college and whether the military will pay of any of your debt. If you haven't already, join a ROTC program at your high school.
