燃油和油量指示系统组件的最低性能标准

[中文适用范围]： 涉及多种航空动力装置的燃油供给链路，重点针对传感器、管路、阀门及指示仪表等组件的性能边界进行界定。标准详细描述了测试方法、工况条件及合格判定准则，确保各部件在复杂飞行姿态和极端温度变化中仍能维持准确、连续的燃油状态监测功能。此类技术规范有助于消除设计差异，提升航空燃油系统的整体安全性与互操作性，为制造商和用户提供了明确的技术参考框架。 [外文原描述]： This AS defines components in "Capacitance Sensor" and "Non-Capacitance Sensor" type Fuel and Oil Quantity Indicating Systems. "Non-Capacitance" systems may employ any measurement technique current in the art including, but not restricted to, float, ultra-sonic and fiber optic devices.The definition of the individual components contained herein is related to the specified Total Installed System accuracy of the entire Fuel or Oil Quantity Indicating System which is a part of the airframe manufacturer's type certification approval data. This data shall be available from the subject airframe manufacturer as published in the operating manual for the aircraft type, model number and configuration. The Fuel or Oil Quantity Indicating System may incorporate optimum compensation based upon measurement of dielectric constant, temperature or density to correct for variations in fuel or oil characteristics due to temperature grade variations or additives. Examples of the type of components covered by this AS are as follows:Cross Reference: FAR25.1359,RTCADOC.DO-160A
