The professional engineer requirements are pretty standard across enginering disciplines, as far as I know. Very few aerospace engineers actually bother to become a professional engineer. The reason is that a professional engineer LICENSE is required by someone who has to officially approve engineering design specifications, USUALLY someone self-employed or working for a small business. Most aerospace engineers work for BIG companies or the government and THEREFORE do not need to become professional engineers. The requirements are to pass a Fundamentals of Engineering exam (that takes a grueling four hours), work under a licensed professional engineer for four years (difficult to do in the aerospace field because there are so few professional engineers to work under) and then take a Principles and Practice of Engineering exam (this one requiring EIGHT hours).
