In ERAU you can do an accelerated program Bachelor's & Master's in five years. The Aerospace Engineering program is ranked #1 by U.S. News & World Report as the #1 aerospace engineering program at a non-Ph.D.-granting university. Riddle definitely has an excellent engineering program no doubt about that, but if you want to fly. I recommend flying off campus, add it as your minor which is easy to do, and youre set to go.
I attend the Daytona Campus (Class 08) So I cant help you there on the AZ side. But If you go to erau.edu then to communities AZ. All your question will be answered. As well for Purdue, they have communities boards for guidance.
Best of Luck
