    • Methods and systems for aircraft engine trend monitoring include periodically re cording the outputs of engine-condition sensors and analyzing the results to examine piston- engine performance trends and predict the need for engine maintenance. Various analyses can be performed, separately or in parallel, including comparing the current parameter val ues with values recorded for that parameter in previous instances of similar operating con ditions; comparing parameter values to predetermined nominal ranges; and detecting pa rameter values that exhibit trends over time that if followed would result in out-of-bound readings. Sensed parameter values can also be used to detect when recommended engine operating conditions are being exceeded. By using the results of the analyses to inform en gine maintenance scheduling and provide alerts to the pilot and maintenance staff regarding recommended engine performance trends and/or operating condition exceedances, the methods and systems contribute to enhancing the level of safety that can be achieved de spite significant maintenance-budget reductions.
    • 飞机发动机趋势监测的方法和系统包括定期重新列出发动机状态传感器的输出,并分析结果以检查活塞 - 发动机性能趋势并预测发动机维护的需要。 可以单独地或并行地执行各种分析,包括将当前参数值与在先前类似操作条件下的该参数记录的值相比较; 将参数值与预定的标称范围进行比较; 并检测出随时间呈现趋势的参数值,如果遵循,将导致超限读数。 传感参数值也可用于检测何时超过推荐的发动机工作条件。 通过使用分析结果来通知维护计划,并向驾驶员和维护人员提供关于推荐的发动机性能趋势和/或操作条件超限的警报,该方法和系统有助于提高可实现的安全等级 尽管显着的维护预算减少。
