Establishment of requirements and evaluation yardstick used in assessing helicopter engine control systems; specifications for single engine helicopters and engine response characteristics which must be compatible include engine stall margin, engine power delivery characteristics, fuel control governing sensitivity, system lags, governor authority and rate (static droop), rotor rpm decay characteristics and autorotative rotor speed sensitivity to weight and altitude, transmission torque limitations, optimum rotor rpm latitude, and mission of aircraft; problem areas discussed also apply to twin-engine installation with additional problem of power sharing.
