Aeronautical Engineering career question?

Aeronautical engineering is, simply stated, the engineering of aircraft and air (fluid) flow science. A degree in this major is used to design aircraft, avionics, and even propulsion systems.

Richard describes it well. I actually specialized in Aeronautics as part of my Engineering Physics Bachelors degree at the University of British Columbia. An aeronautics program can be challenging from a mathematical, physics, and computer programming perspective, but is just as rewarding in terms of tying together theory and practice, tools and reality.
