Thrust levers in a Boeing 747 Classic. The center and rear levers are used during flight, while the forward levers control reverse thrust.. Thrust levers or throttle levers are found in the cockpit of aircraft, and are used by the pilot, copilot, flight engineer, or autopilot to control the thrust output of the aircraft's engines, by controlling the fuel flow to those engines. [1]
For a gasoline engine, the throttle most commonly regulates the amount of air and fuel allowed to enter the engine. However, in a gasoline direct injection engine, the throttle regulates only the amount of fuel allowed to enter the engine. Historically, the throttle pedal or lever acts via a direct mechanical linkage. The butterfly valve of the ...
Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the aircraft, providing deceleration. Thrust reverser systems are featured on many jet aircraft to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing ...
Thrust levers of an A320 set to the autothrust position during cruise flight. An autothrottle (automatic throttle, also known as autothrust, A/T or A/THR) is a system that allows a pilot to control the power setting of an aircraft's engines by specifying a desired flight characteristic, rather than manually controlling the fuel flow.
The flight crew accordingly carried out the necessary ECAM actions with No. 2 engine's thrust lever moved to the idle (or minimum-thrust setting) position. The crew set No. 1 engine to maximum continuous thrust to compensate for the low thrust of No. 2 engine.
Thrust lever or throttle, which controls engine speed or thrust for powered aircraft. The control yokes also vary greatly among aircraft. There are yokes where roll is controlled by rotating the yoke clockwise/counterclockwise (like steering a car) and pitch is controlled by moving the control column towards or away from the pilot, but in ...
When the pilot wants more thrust the rate of increase in fuel flow that comes with moving the thrust lever (throttle) must not be too great but at the same time must be enough to accelerate the engine quickly without stalling the compressor. When reducing thrust the rate at which the fuel decreases must not be too quick or a flame-out will occur.
The engine is designed to operate at a constant speed, no matter the thrust output—a characteristic permitted by the Astafan's use of precise fuel metering and fan blade pitch adjustment. [1]: 555 To control the engine, the pilot first sets the speed lever, which adjusts fuel flow in proportion to the selected engine speed.
