The piloting profession is very diverse. A pilot's mission varies significantly depending upon the type of operation he or she is involved in, such as crop dusting, instructing, helicopter flight, military operations, regional airlines or transoceanic international flights on the new Airbus A380. Pilot training was focused on two areas: classroom and practical. Classroom instruction dispensed knowledge about aircraft structures, flight controls, aerodynamics, engines and rules of the air. The practical application was learning to fly, or the "hands-and-feet" skills. Advanced Qualification Program (AQP) is a voluntary alternate pathway for traditional pilot training regulations. While some Flight Crew Licensing and Training Panel panelists advocated the use of AQP to define competence, others held the perspective that pilot competencies were driven by non-technical skills. The structure established for the multi-crew pilot license competency framework has been used for competency frameworks of all the other aviation professional groups, with one exception.
