Airbus cockpit retard7/30/2023 The final airspeed should remain constant. As the pilot commands a pitch up to climb or banks into a turn, the autothrottle system automatically commands more power to the engines. Olivier Cleynen Thrust levers of an Airbus A320Īutothrottle technology uses the aircraft’s angle of attack to choose an appropriate amount of power to maintain specific airspeeds. Likewise, the system will optimize power settings for every phase of flight, like climb and cruise. By setting the throttles or power levers to max takeoff, the system will deliver the maximum thrust without the pilots fussing over power settings. An autothrottle is an automated technology designed to make the pilot’s job easier and to increase safety. Benefits of AutothrottlesĪutothrottle technology has been around in jetliners and corporate airplanes since the 1950s. Laypeople and aviation outsiders, on the other hand, will wonder how on earth such an abnormal callout every came to be automated into the cockpit of some of the world’s most advanced airliners. When told to retard power, their hands will fly to the power levers, because that word has been associated in their minds to the throttle position. By the time a pilot get to the flight deck of an airliner, he or she has many hours under their belt. On jet-powered aircraft, thrust lever position is usually advanced or reduced. The use of open and closed is related only to reciprocating engines, however. When the throttle is closed, or retarded, the amount of fuel and air is reduced, and power decreases. When the throttle is advanced, or opened, the butterfly valve allows the maximum amount of fuel and air into the cylinders. Often, mechanical throttles found in small aircraft use the terminology open and close, to describe the actions of controlling the butterfly valve inside the carburetor.
