The pitch axis (also called transverse or lateral axis), [5] passes through an aircraft from wingtip to wingtip. Rotation about this axis is called pitch . Pitch changes the vertical direction that the aircraft's nose is pointing (a positive pitching motion raises the nose of the aircraft and lowers the tail).
For example, a pitching moment comes from a force applied at a distance forward or aft of the cg, causing the aircraft to pitch up or down. A fixed-wing aircraft increases or decreases the lift generated by the wings when it pitches nose up or down by increasing or decreasing the angle of attack (AOA).
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 ...
A Boeing 737 uses an adjustable stabilizer, moved by a jackscrew, to provide the required pitch trim forces. Generic stabilizer illustrated. A horizontal stabilizer is used to maintain the aircraft in longitudinal balance, or trim: [3] it exerts a vertical force at a distance so the summation of pitch moments about the center of gravity is zero.

A number of early aviation pioneers, including A. V. Roe and Louis Breguet, used propellers which could be adjusted while the aircraft was on the ground. [3] This was also the case during World War I with one testbed example, "R.30/16", of the Zeppelin-Staaken R.VI German four-engined heavy bomber. [4]
Blade pitch control is a feature of nearly all large modern horizontal-axis wind turbines.It is used to adjust the rotation speed and the generated power. While operating, a wind turbine's control system adjusts the blade pitch to keep the rotor speed within operating limits as the wind speed changes.
The television term “pilot” is likely inspired by the aviation industry, given it's the first time a show lifts off or "airs." Like an airline pilot operating a plane, these episodes steer ...
For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero. Acceleration – In physics, acceleration is the rate of change of velocity of an object with respect to time.
