    The Department of Civil Aviation Engineering was originally founded in September, 1994 as Civil Aviation Engineering College (CAEC) with the approval of the Aviation Industries of China (AVIC) and the Civil Aviation Administration of China (CAAC).

    There are 26 faculty members, including 7 professors, 5 doctor instructors and 14 associate professors and senior engineers. 93% of the faculty members are doctor or master degree holders. 16 of them have the experience of taking professional technical training programs abroad given by Boeing in USA and Lufthansa in Germany.

    The department offers bachelor’s degree in three majors:  flight vehicle design engineering, electronic Information engineering, electrical engineering and automation.

    The department offers master’s degree in four disciplines: means of transport operational engineering, airworthiness technology and management, science of material, communication and information system. The department offers doctor’s degree in the first two disciplines.

    There are two labs: the integrated test, fault simulation & diagnosis lab, the corrosion and protection lab. And there are three research organizations: institute of airborne system airworthiness and maintenance, corrosion and protection center, civil aircraft maintenance engineering research center.

    The department consistently focuses on the targets of building the up-to-date disciplines, managing the state-of-art environment for its education of students, educating high quality students and aiming at perfect performance.
