Abstract: 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.

Abstract: In an embodiment, a method of indicating flight modes of a rotorcraft includes: detecting a change in flight mode of the rotorcraft from a previous flight mode to an active flight mode, the active flight mode and the previous flight mode each being from one of a first subset or a second subset of a plurality of flight modes; determining whether the active flight mode and the previous flight mode are from different subsets of the plurality of flight modes; and updating one or more flight mode indicators on an instrument panel of the rotorcraft in response to the active flight mode and the previous flight mode being from different subsets of the plurality of flight modes.
