On the most fundamental level, flying is about controlling three axis – pitch, yaw, and roll. However, in today’s dynamic cockpit environment, there is a fourth axis to control…speed. The mission of AutoPower® – the Automatic Throttle System (ATS) from Safe Flight Instrument Corporation – is the precise management of speed through the control of thrust during all phases of flight. Safe Flight pioneered the development of automatic throttle technology which is now standard equipment on most large transport aircraft. Today, Safe Flight brings this level of cockpit sophistication to the Gulfstream G150. AutoPower® delivers significant flight performance advantages resulting in reduced crew workload and increased situational awareness. Precise Speed Control AutoPower® is an automatic throttle system designed to provide precise air speed control and engine target settings, from takeoff to touchdown. AutoPower® manages N1 for takeoff, climb, and go-around power modes and for speed control. It delivers smooth and precise speed control, increased situational awareness, reduced crew workload, greater passenger comfort, increased payloadrange potential, and fuel savings. AutoPower® manages engine thrust through the aircraft’s thrust levers, keeping the pilot in the loop. When the system changes thrust, the thrust levers move. Overriding the throttles never takes more force than moving the throttles when AutoPower® is not engaged. Flight crew transition to AutoPower® operation is intuitive. The system automatically controls thrust during takeoff, climb, cruise, approach, landing, and go-around. It integrates seamlessly with the AFCS vertical modes while automatically capturing the selected speed, Mach number, or N1 position.
