摘　　要：飞机燃油量测量系统是飞机燃油系统的重要组成部分,用于测量和指示飞机各个油箱的可用燃油量以及飞机总可用燃油量。燃油量测量精度是飞机燃油量测量系统的重要性能指标,可分为地面姿态下的燃油量测量精度和空中燃油量测量精度。地面姿态下的燃油量测量精度可通过地面标定试验的方法标定出其实际精度;在空中时由于无法得知飞机油箱的真实燃油量,因此无法通过试验的方法标定出其空中实际精度,空中燃油量测量精度需结合地面标定的精度以及空中精度分析最终给予说明。本文介绍了大型民用飞机在地面姿态下的燃油量测量精度标定方法,主要内容包括标定点的选取、标定方法、合格判据、数据处理等。Aircraft fuel measurement system is an important part of aircraft fuel system,which is used to measure and indicate the available fuel amount of each tank and the total available fuel amount of aircraft.Fuel measurement accuracy is an important performance index of aircraft fuel measurement system,which can be divided into ground attitude and in the air.The accuracy of ground aircraft fuel measurement system can be calibrated by the method of ground calibration test.Since the actual fuel quantity of aircraft cannot be known in the air,it is impossible to calibrate the accuracy of aircraft fuel measurement system in the air through test method,the accuracy of aircraft fuel measurement in the air should be explained by combing the accuracy of ground calibration and air analysis.This paper introduces the calibration method of fuel measurement system of large civil aircraft in ground attitude,including the selection of standard point,calibration method,qualification criterion,data processing and so on.
