Relationship of course to program objectives:

AAE 520 contributes to the following program objectives:

1) Acquire the essential technical components of aerospace engineering.

2) Develop basic engineering skills:

a) An ability to formulate and solve problems, including experimental, open-ended and design problems

b) An ability to work in teams

c) The ability to communicate their work to others, in writing, orally, and graphically

d) A habit of professional conduct.

3) Have opportunities for research, independent study
