System and method for electronic lateral-directional stability augmetnation

A method for providing electronic lateral and directional stability for an aircraft, the method comprising:

• receiving with compensation modules input from sensors mounted to the aircraft, wherein the sensors are configured for sensing one or more conditions experienced by the aircraft in real time;
• determining compensation commands via the compensation modules, wherein the compensation commands include instructions for at least one servo motor based upon the input from the sensors;
• and
• outputting the compensation commands to a servo control and dynamics system including the at least one servo motor, wherein the at least one servo motor is physically coupled to an aircraft control inceptor and is configured to, based on the compensation commands, provide reactive forces to flight surfaces of the aircraft that work against the pilot or assists the pilot as the pilot manually manipulates the aircraft control inceptor.

• determining compensation commands via the one or more compensation modules based on input from the sensors, wherein the one or more compensation modules are configured to determine the compensation commands according to at least one of the following:
• reduce roll force based on speed or roll rate,
• modify roll force with estimated side slip,
• increase rudder force with side slip to prevent rudder force lightening,
• level wings of the aircraft to drive the aircraft to level when bank angles are less than a predetermined angle,
• provide yaw damping in a torque mode, and
• provide rudder bias force when at least one engine is not operating;
• summing the compensation commands from a plurality of the compensation modules into a lateral or directional stability compensation command, wherein the summing is performed in a weighted manner in accordance with flight control requirements;
• and
• outputting the lateral or directional stability compensation commands to a servo control and dynamics system including at least one servo motor, wherein the at least one servo motor is physically coupled to an aircraft control inceptor and is configured to provide reactive forces via actuation of flight surfaces of the aircraft that work against the pilot or assists the pilot as the pilot manually manipulates the aircraft control inceptor.
