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.

Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1. Intake 2. Low pressure compression 3. High pressure compression ...
In contrast, a propeller set for good cruise performance may stall at low speeds, because the angle of attack is too high. A propeller with adjustable blade angle is more efficient over a range of conditions. A propeller with variable pitch can have a nearly constant efficiency over a range of airspeeds. [1]
A 1918 sketch of ground crew receiving instruction on hand starting. Hand starting of aircraft piston engines by swinging the propeller is the oldest and simplest method, the absence of any onboard starting system giving an appreciable weight saving.
Cockpit controls and instrument panel of a Cessna 182D Skylane. Generally, the primary cockpit flight controls are arranged as follows: [2] A control yoke (also known as a control column), centre stick or side-stick (the latter two also colloquially known as a control or joystick), governs the aircraft's roll and pitch by moving the ailerons (or activating wing warping on some very early ...
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.
To increase or decrease overall lift requires that the controls alter the angle of attack for all blades collectively by equal amounts at the same time, resulting in ascent, descent, acceleration and deceleration. A typical helicopter has three flight control inputs: the cyclic stick, the collective lever, and the anti-torque pedals. [2]
The static rollover critical angle can be determined by measuring the angle between level ground and an imaginary line drawn from skid to skid, when the helicopter's center of gravity is located on the upward pivot line. [4] [5] Static rollover also pertains to automobiles. In the study of roll stability of vehicles, the static rollover ...
