A recently granted patent (Publication Number: US11884379B2) discloses a control system for a high lift assembly on an aircraft, allowing for the adjustment of the assembly into different aerodynamic configurations to control lift. The system includes a manual control device operated by the pilot, comprising a movable member and a base body. A lift control unit is connected to the manual control device, generating lift control vectors based on input data from the manual control device, including signals from a rest detection system for detecting the position of the movable member.

Furthermore, the control system incorporates a visual indication device on the manual control device to display the commanded aerodynamic configuration to the pilot. The system also includes features such as redundancy in position sensors, transitional visual indications for configuration changes, and authorization indicators for switching between different aerodynamic configurations based on flight parameters. The manual control device, which can be a joystick with a lever, is designed to emit signals when the lever reaches specific positions, triggering changes in the high lift assembly's aerodynamic configurations. Overall, the patented control system offers a comprehensive and innovative approach to efficiently manage the high lift assembly on an aircraft, enhancing control and safety during flight operations.
