Abstract
Methods and systems for adjusting a force feel profile of an inceptor of an aircraft are provided. The force feel profile is based on a baseline value of an operating parameter of the aircraft and defines an amount of resistive force applied to the inceptor as a function of displacement of the inceptor. An embodiment of the method includes receiving data indicative of a current value of the operating parameter. Based on a difference between the current value and the baseline value of the operating parameter, a portion of the force feel profile corresponding to a range of displacement values is shifted to adjust an amount of resistive force defined by the portion of the force feel profile for the range of displacement values.
Claims18
A method of controlling a resistive force of an inceptor of an aircraft according to a force feel profile defined as a two-dimensional graph having a first axis representing displacement values for the inceptor and a second axis representing corresponding resistive force values applied to the inceptor, the force feel profile being based on a baseline value of a first operating parameter of the aircraft and on a baseline value of a second operating parameter of the aircraft different from the first operating parameter, the method comprising:
- using a current value of the first operating parameter and a current value of the second operating parameter, shifting a portion of the force feel profile along the second axis by an amount determined using:
- a product of a first constant and a difference between the current and baseline values of the first operating parameter;
- and
- a product of a second constant and a difference between the current and baseline values of the second operating parameter, the first constant being different from the second constant;
- and
- controlling the resistive force of the inceptor according to the force feel profile including the shifted portion.
A system for controlling an inceptor of an aircraft according to a force feel profile defining an amount of resistive force applied to the inceptor as a function of displacement of the inceptor, the force feel profile being based on a baseline value of a first operating parameter of the aircraft and on a baseline value of a second operating parameter of the aircraft different from the first operating parameter, the system comprising:
- an actuator configured to apply the resistive force to the inceptor;
- one or more data processors operatively coupled to the actuator;
- and
- non-transitory machine-readable memory storing instructions executable by the one or more data processors and configured to cause the one or more data processors to:

- and
- cause the actuator to apply the resistive force to the inceptor according to the force feel profile including a portion of the force feel profile shifted by an amount determined using:
- a product of a first constant and the difference between the current and baseline values of the first operating parameter;
- and
- a product of a second constant and a difference between the current and baseline values of the second operating parameter, the first constant being different from the second constant.
