摘要： A rotorcraft including a control element, a control sensor connected to the control element, where the control sensor is operable to generate trim data indicating a displacement of the control element in relation to a trim position of the control element, and a flight control computer (FCC) operable to monitor the trim data and determine an active detent state of the control element. The active detent state is one of an in-detent state, an out-of-detent state, and an in-transition state. The FCC is operable to buffer a transition of the active detent state from the in-detent state to the out-of-detent state using the in-transition state. The FCC provides a first flight management function when the active detent state is the in-detent state or the in-transition state, and provides a second flight management function when the active detent state is the out-of-detent state.

摘要： An rotorcraft including a pilot control, a pilot control position sensor connected to the pilot control and operable to generate a position signal indicating a position of the pilot control, a flight control computer (FCC) in signal communication with the pilot control position sensor and operable to provide a tactile cue in the pilot control in response to the position signal indicating the position of the pilot control exceeds a threshold associated with an operating limit, and further operable to determine a tactile cueing value for the tactile cue according to a relationship between the position of the pilot control and the threshold, and generate a cue control signal according to the tactile cueing value, and a tactile cue element connected to the pilot control and in signal communication with the FCC and operable to control action of the pilot control in response to the cue control signal.
