FULL AUTHORITY FLY-BY-WIRE PEDAL SYSTEM
First Claim
1. A method of controlling a yaw axis of a rotary-wing aircraft comprising the steps of:
- (A) maintaining stability and coordination through a fly-by-wire flight control system;
and(B) receiving a pilot yaw control input only when a change in a yaw axis state is demanded, the pilot yaw control input provided through a double gradient force feedback pedal dynamic for control of an anti-torque system.

Abstract
A pedal system particularly tailored to a Fly-By-Wire (FBW) flight control system includes a double gradient linkage assembly. The double gradient linkage assembly includes a damper system and a spring system that improves yaw axis (azimuth) control of the aircraft. Control is only required when a change in the yaw axis state is demanded. Since only minimal displacement inputs to such a FBW flight control system is required, the travel of the pedals are exceeding compact, such that pilot workload is significantly reduced through the reduction in the frequency and magnitude of aircraft control inputs.
