A flight control system includes a controller which defines a controller displacement and a control surface which defines a control surface authority. A module operable to provide a displacement feel to the controller in response to a remaining portion of the controller displacement being greater than a remaining portion of the control surface authority and the module operable to re-reference a center of the controller displacement to equate the remaining portion of the controller displacement with the remaining portion of the control surface authority in response to the remaining portion of the controller displacement being less than the remaining portion of the control surface authority.

1. A flight control system comprising: a controller which defines a controller displacement;a control surface which defines a control surface authority;a module providing a displacement feel to said controller in response to a remaining portion of said controller displacement being greater than a remaining portion of said control surface authority and said module operable to re-reference a center of said controller displacement to equate said remaining portion of said controller displacement with said remaining portion of said control surface authority in response to said remaining portion of said controller displacement being less than said remaining portion of said control surface authority. 2. The system as recited in claim 1, wherein said controller includes a yaw pedal system. 3. The system as recited in claim 2, wherein said displacement is defined by a yaw pedal end stop. 4. The system as recited in claim 2, wherein said control surface is a tail rotor system. 5. The system as recited in claim 4, wherein said displacement feel directly relates movement of said yaw pedal system to movement of said tail rotor system. 6. The system as recited in claim 1, wherein said auto-trim logic is operable to actuate a trim integrator to re-reference said center of said controller. 7. The system as recited in claim 1, wherein said remaining controller displacement is related to a remaining distance to a yaw pedal end stop of a yaw pedal system. 8. The system as recited in claim 7, wherein said remaining control surface displacement is related to a remaining servo authority of a tail rotor system. 9. The system as recited in claim 1, wherein said module provides a unique-trim control as modified by said auto-trim logic. 10. The system as recited in claim 1, wherein said module is operable only in a direct mode. 11. The system as recited in claim 1, wherein said module is operable only when the aircraft is on the ground. 12. The system as recited in claim 1, wherein said controller is located within an aircraft cockpit. 13. A method of flight control comprising: providing a displacement feel to a controller in response to a remaining portion of a controller displacement being greater than a remaining portion of the control surface authority; andre-referencing a center of the controller displacement to equate the remaining portion of the controller displacement with the remaining portion of the control surface authority in response to the remaining portion of the controller displacement being less than the remaining portion of the control surface authority. 14. A method as recited in claim 13, further comprising enabling controller feed forward to a trim integrator in response to the remaining portion of the controller displacement is less than the remaining portion of the control surface authority. 15. A method as recited in claim 13, disabling the feed forward in response to the remaining portion of the controller displacement is equal to the remaining portion of the control surface authority. 16. A method as recited in claim 13, wherein the providing the displacement feel to the controller and the re-referencing the center of the controller displacement only occurs when the flight control system is in a direct mode. 17. A method as recited in claim 13, wherein the providing the displacement feel to the controller and the re-referencing the center of the controller displacement only occurs when the aircraft is on the ground.
