Sorry it took me so long to get back with some more info...
Purdue's Aviation Department is a part of the School of Technology, and features 3 majors - aeronautical technology (maintenance), aviation administration, and flight. If you enter the flight program with no private certificate, as most people do, you will earn one in your first semester, while flying brand new Piper Warrior IIIs. Over the two following semesters, you will learn commercial maneuvers and build time in the Warriors, followed by a semester in Piper Arrows, during which you will earn your instrument rating and commercial certifiacte. Each semester during the second year also features a course in the Frasca flight training device to learn instrument procedures. In the first semester of your junior year, you will fly the Beechcraft Duchess, earning your multi-engine rating, and begin to take classes on the 727 and King Air. Simultaneously, you enter the 727-100 simulator. Finally, in the second semester of your junior year, you upgrade to the 727-200 and become eligible to fly the King Airs (all flight students fly the King Airs, but the semster during which you fly it varies from spring of the junior year to fall of the senior year so that there is a steady supply of copilots year round.)
At the same time that you are undergoing the flight training, you would take other classes as well. Some of the classes required are general education (math, physics, english, communications, psychology, etc.), but most are aviation or aviation related. Coursework includes classes on aircraft powerplants, aircraft systems (general as well as 727 and King Air), crew resource management, aviation weather, ethics and professionalism in aviation, human factors, turbine flight operations, high altitude operations, navigation, and more. Additionally, as a Big Ten University, Purdue offers a large selection of courses in other disciplines as well, so you can take other courses that interest you if you choose to do so. For example, quite a few people in AvTech (aviation technology) are taking a minor in management from the Krannert School of Management.
In all, I have had a great experience with Purdue so far. The faculty really is the best I could imagine. Many of the professors are former airline pilots, while others are career aviator-educators. The staff members all make themselves available to students outside of class for extra help or just to talk, and they make it blatently obvious that they are here because they enjoy working with students - not because the university is paying them to do research. With a campus of roughly 37,000 students, we have a full college experience, and our aviation program is well renowned throughout the industry, with at least one airline expressing a preference for a 300 hour Purdue grad over a 1500 hour pilot who did not go to school here. The only downside I see to Purdue is location (as a San Diegan, I just can't get used to the Indiana topography!), but it's worth it to go to school here.
Hope this has helped - let me know if you have any questions regarding Purdue, our program, or anything else.
