Nonlinear fly-by-wire aircraft control

A method of electronically controlling a rotorcraft, comprising:

• receiving via a first data source a flight control displacement;
• receiving via a second data source a secondary condition;
• querying a data structure with the flight control displacement and the secondary condition;
• and
• translating the flight control displacement into an actuator displacement according to a gain value received from the data structure.

A rotary aircraft, comprising:

• an operator flight control system;
• an engine;
• a rotor blade drive system mechanically coupled to the engine;
• a fly-by-wire control system comprising electronically controllable actuators to adjust flight control surfaces to affect yaw, pitch, and roll of the rotary aircraft;
• an environmental sensor;
• and
• a flight computer comprising a processor microcircuit and logic to:
• receive an input from the flight control system;
• receive an environmental datum from the environmental sensor;
• query an n-dimensional ratio table, n>2, for an actuator ratio according to the input and the environmental datum;
• and
• actuate the fly-by-wire control system according to the actuator ratio.
