Abstract: The importance of aircraft supportability is related and its connotation and the approach of its realization are discussed, and some new aircraft design methods for supportability are briefly introduced in this paper. On the basis of the definition of weapon system supportability, aircraft supportability si referred to the integration of reliability, maintainability and onboard support capability of aircraft itself and the support capability of aircraft's support subsystem. Supportability is to be realized by means of integrated support engineering, i.e. integrated logistics support. The main missions of the engineering are to influence aircraft's design for supportability from the point of view of operational support, including putting forward the supportability-related requirements and assurance of their realization, and to design systematically and to acquire the aircraft's support subsystem based on the operational support requirements derived from the aircraft's design. The main tasks of the engineering are to work out a maintenance concept and to make supportability analysis, i.e. logistics support analysis.

Key words: aircraft, supportability, design, integrated support engineering, integrated logistics support
