Aircraft Control Stick Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft piloting systems are complex for crew members to use for both short-term and middle-term piloting, requiring multiple control members and modes, which complicates the generation of primary and secondary set points.
Innovation Solution
A method and device that allow switching between primary and secondary set point generation modes using a single control member, such as a control stick or throttle, based on acquired mechanical properties, enabling the computation and generation of set points for flight control, engine control, and guidance systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional flight conduct systems use separate control members for primary and secondary set points, then the generation of set points can be achieved, but the system becomes complex to use by the crew
Solution Approach 1:
The control stick is designed to perform multiple functions: it can generate both primary set points (for flight control system) and secondary set points (for guidance system) depending on the operational mode. The stick includes a first position for generating primary set points and a second position for generating secondary set points, allowing one control member to replace what would traditionally require multiple separate control members
Solution Approach 2:
The control stick incorporates a movable component that can be positioned in different locations along the stick. This dynamic positioning capability allows the stick to switch between different operational modes: when the movable component is in the first position, the stick generates primary set points; when in the second position, it generates secondary set points. This dynamic reconfiguration enables a single control member to adapt its function based on operational needs
2Adaptability or versatility
If multiple control members are used for generating primary and secondary set points, then comprehensive control capability is achieved, but the number of control members increases
Solution Approach 1:
The control stick serves as a universal control member that can generate both types of set points. By incorporating a movable component with selectable positions, the stick provides comprehensive control capability for both the flight control system and guidance system without requiring separate dedicated control members for each function
Solution Approach 2:
The invention merges the functionality of multiple control members into a single control stick. The stick integrates both primary set point generation (for short-term flight control) and secondary set point generation (for middle-term guidance) capabilities, combining what would traditionally be separate control devices into one unified control interface

AI summary
A method and device for generating at least one set point from a flight control set point, a motor control set point and an aircraft guidance set point, a related computer program product and an aircraft are disclosed. In one aspect, the method includes acquiring a mechanical property relative to at least one corresponding primary control member and computing at least one set point from among one or more primary set points and one or more secondary set points. The method also includes generating at least one of the computed set point(s) and switching, based on the mechanical property acquired for the corresponding primary control member, between a first mode in which one or more primary set points are generated and a second mode in which one or more secondary set points are generated.
