SYSTEM AND METHOD FOR ROTORCRAFT HEIGHT CONTROL

A method of operating a rotorcraft includes receiving multiple first height data signals from multiple first height sensors on the rotorcraft, wherein the first height sensors measure height using a first technique, receiving multiple second height data signals from multiple second height sensors on the rotorcraft, wherein the second height sensors measure height using a second technique that is different than the first technique, determining a first height signal from the multiple first height data signals based on a selection scheme, determining a second height signal from the multiple second height data signals, selecting the first height signal or the second height signal to determine a selected height signal, and generating a flight control signal and controlling operation of the rotorcraft according to the flight control signal, the flight control signal based on the selected height signal. 一种操作旋翼飞行器的方法，包括：从旋翼飞行器上的多个第一高度传感器接收多个第一高度数据信号，其中，第一高度传感器使用第一技术测量高度；从旋翼飞行器上的多个第二高度传感器接收多个第二高度数据信号，其中，第二高度传感器使用与第一技术
