Aviation engineering involves the operational activities of an aircraft, including maintenance, safety measures, and other performance activities. It entails the processes of compliance with the industry and ensuring efficiency and airworthiness of the aircraft. This professional practices in aviation system, avionics, and flight operation problem diagnostics.
Aeronautical engineering is a subdivision in aerospace engineering which deals with the design, development, and systems analysis of an aircraft including the aerodynamics, propulsion, and structures. It involves the creation of new systems and technologies to increase performance, fuel economy, and safety of flights. Aeronautical engineers perform research and development testing of aircraft and components. Out of all branches of aviation, aeronautical engineering is the most scientific and design oriented while aviation engineering is pragmatic and operationally focused.
