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.

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 ...
The term throttle has come to refer, informally, to any mechanism by which the power or speed of an engine is regulated, such as a car's accelerator pedal. What is often termed a throttle (in an aviation context) is also called a thrust lever, particularly for jet engine powered aircraft.
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.
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.
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 ...
In February 2012, GE announced studies on a more efficient derivative of the GE90, calling it the GE9X, to power both the -8 and -9 variants of the new Boeing 777X.It was to feature the same 128 in (325 cm) fan diameter as the GE90-115B with thrust decreased by 15,800 lbf (70 kN) to a new rating of 99,500 lbf (443 kN) per engine.
