    • The accuracy of flight management systems, based on mathematical prediction models calculated from aircraft specific data, are improved by adding engine sensor data to the calculations, checking sensor and pilot entered data, and comparing data measured from redundant sensors. A thrust estimate, calculated from available engine sensors (20-22, 26) is added to the thrust-minus-drag aircraft model allowing prediction parameters to be accurately calculated even in a cruise condition. Sensor data and pilot entered data used in calculating predication parameters are checked to improve accuracy. Redundant sensor data is compared to determine the level of agreement. Redundant sensor data is also compared with a valid data range to find the sensor with the most accurate data.
    • 通过将发动机传感器数据添加到计算,检查传感器和飞行员输入的数据,以及比较从冗余传感器测量的数据,可以改进飞行管理系统基于从飞机特定数据计算的数学预测模型的准确性。 从可用的发动机传感器计算出的推力估计值被加到推力减阻飞行器模型中,即使在巡航条件下也能够准确地计算预测参数。 检查用于计算预测参数的传感器数据和导频输入数据,以提高精度。 比较冗余传感器数据以确定协议级别。 还将冗余传感器数据与有效数据范围进行比较,以找到具有最准确数据的传感器。
