Health monitoring technology is the key technology to improve the safety, combat readiness and quick response ability of equipment, which has become the necessary technology of modern high-tech equipment.In order to characterize the aircraft health status clearly and effectively, the parameters "health degree" is put forward to characterize the health level of aircraft and its sub-systems.Based on it, the calculation and determination methods of the basic health degree and the mission health degree of aircraft and its sub-systems were given out.Then, the health status evaluation methods of aircraft and its sub-systems were established based on the "health degree" parameter as well as the "healthy", "sub-healthy" and "unhealthy" employed to express the typical three healthy statuses of them.Finally, the condition-based maintenance(CBM) strategies for aircraft and its sub-systems based on the health statuses were described by means of an example:the aircraft and its sub-systems do not need maintenance when they are healthy, the aircraft and its sub-systems need to make maintenance plan when they are subhealthy, the aircraft and its sub-systems need maintenance at once when they are unhealthy, and the final implementation maintenance strategy should be carried out considering the economic requirements.The results of this paper lay a foundation for the effective applications of health monitoring technology in aircraft and its sub-systems, and they can also be extended to the health monitoring of other equipment and systems.
