近年来，可编程逻辑器件在航空机载设备中的应用越来越多，其设计也变得愈发复杂，适航认证已成为航空器件发展的必然趋势。DO-254标准的有效性得到了美国联邦航空局和欧洲航空安全局等业界权威的一致确认，为机载电子硬件的设计开发提供了指导与保障。本文从DO-254中硬件的生命周期出发，对可编程逻辑器件在生命周期的各个阶段如何开展质量保证活动进行了深入研究，以确保机载设备的安全性与可靠性，降低航空可编程逻辑器件的开发风险。%In recent years, airworthiness certifi cation has become an inevitable tendency in the development of aviation devices because of the popularly application in the aviation devices and complicated project of PLD. DO-254 provides guidance and protection of airborne electronic hardware design and its effectiveness has been unanimously confi rmed by the industry authority of the FAA and the European Aviation Safety Agency. To ensure the safety and reliability of airborne equipment and reduce the risk of developing aviation programmable logic devices, this paper deeply researches how to carry out quality assurance at all stages of the life cycle of programmable logic device with the start of the life cycle of hardware in DO-254.
