Application of design pattern in MBIT ground software of flight control system

Maintenance built-in-test (MBIT) system of Flight control system is the major software for pre-flight test. As the flight control system is the core of a plane, its system testing and fault diagnosing has very important significance. In order to quickly adapt to the flight control system, design patterns were introduced in this software, which provides a range of easy operation, high reliability, interactive software for the ground staffs. This paper introduces the concepts and functions of the ground system, and describes the application of several design patterns in MBIT ground system. After the test of practice, the application of design patterns makes the software low coupling, high reliability and easy maintenance.
