飞机可用性是反映飞机维修性、可靠性和运行成本的重要指标之一。因此,在飞机设计和运营的过程中在应在不超出适航规范内尽可能提高飞机的利用率。通过对国外飞机制造商的保障性工程,维修大纲和飞机监控管理等提高飞机可用性的措施进行分析,为国内飞机可用性的设计和管理提高提供了借鉴。 Aircraft availability is one of the key indicators of aircraft maintainability, reliability and operating costs. Therefore, during the design and operation of the aircraft, the utilization of the aircraft should be as high as possible without exceeding the airworthiness standards. By analyzing the measures to improve aircraft usability, such as the assurance engineering of foreign aircraft manufacturers, maintenance programs and aircraft monitoring and management, it provides reference for the design and management of domestic aircraft usability improvement.
