Within the course “Aircraft maintenance” students will gain basic knowledge concerning contemporary theories and praxes in the maintenance and revitalization of both military and civil aircrafts. Furthermore, a part of the course is dedicated to exploration of maintainability, reliability of fighting tenacity, as well as the basic structural characteristics of the system that are defined in the early stages of design and development of modern aircrafts.
After mastering the curriculum, students will be capable of creative thinking and decision making in the domain of aircraft maintenance. By gaining sufficient theoretical and practical knowledge, they will be able to participate equally in a working team designing or maintaining the aircraft and to further improve important flight characteristics such as reliability, maintainability, fighting tenacity or durability (particularly in cases of forced landings).
