Takeoff/Landing Touchdown Protection Management System
First Claim
1. An air/ground contact logic management system for use in an aircraft, comprising:
- a first sensor configured to provide an output signal;
a logic management system in communication with the first sensor being configured to receive and process the output signal and classify a mode of the aircraft; and
a controller in communication with the logic management system to receive signal data from the logic management system, the controller being in communication with a control axis actuator to regulate a level of control authority provided to a pilot based upon the mode of the aircraft.

Abstract
An air/ground contact logic management system for use with fly-by-wire control systems in an aircraft. The system includes a first sensor configured to provide an output signal to determine when the aircraft is in a transition region. A logic management system is in communication with the first sensor and is configured to receive and process the output signal and classify a mode of the aircraft. A controller receives signal data from the logic management system and communicates with a control axis actuator to regulate a level of control authority provided to a pilot. The control authority is individually regulated within each integrator as a result of the individual landing gear states.

14. An aircraft comprising:
-
a landing gear coupled to the aircraft; a fly-by-wire control system used to control the aircraft; and a air/ground contact logic management system configured to communicate with the fly-by-wire control system to regulate control authority during selected maneuvers, the air/ground contact logic management system including; a first sensor coupled to the landing gear and configured to transmit an output signal pertaining to a landing gear state condition; a logic management system in communication with the first sensor being configured to receive and process the output signal and classify a mode of the aircraft based upon the landing gear state condition; and a controller in communication with the logic management system to receive signal data from the logic management system, the controller being in communication with a control axis actuator to selectively regulate the level of control authority provided to a pilot based upon the mode of the aircraft. - View Dependent Claims (15, 16)

17. A computer-implemented method for regulating the control authority of an aircraft, the method being performed using one or more processing units, the method comprising:
-
receiving an output signal from at least one sensor; assigning an integer value to the output signal, the integer value being predetermined by a mathematical method programmed into a logic management system; compiling the integer values from the at least one sensor into a total score; transmitting the integer values and the total score to a score management logic; determining a mode of the aircraft through the score management logic, the mode of the aircraft being based upon the total score; and regulating an axial control actuator to adjust the control authority of a pilot, the axial control actuator being controlled through a controller in communication with the score management logic and existing fly-by-wire control laws in the aircraft. - View Dependent Claims (18, 19, 20)
