A yoke, alternatively known as a control wheel or a control column, is a device used for piloting some fixed-wing aircraft. [1] The pilot uses the yoke to control the attitude of the plane, usually in both pitch and roll. Rotating the control wheel controls the ailerons and the roll axis.
When the pilot moves the aileron control to the left, or turns the wheel counter-clockwise, the left aileron goes up and the right aileron goes down. A raised aileron reduces lift on that wing and a lowered one increases lift, so moving the aileron control in this way causes the left wing to drop and the right wing to rise.
Some pilots consider hovering the most challenging aspect of helicopter flight. [7] Because helicopters are generally dynamically unstable, deviations from a given attitude are not corrected without pilot input. Thus, frequent control inputs and corrections must be made by the pilot to keep the helicopter at a desired location and altitude.
Holding the reed beater bar in the left hand, and the (picking-stick-mounted) string tugged to return the flying shuttle in the right hand.See video below. In a typical frame loom, as used previous to the invention of the flying shuttle, the operator sat with the newly woven cloth before them, using treadles or some other mechanism to raise and lower the heddles, which opened the shed in the ...
Although its principle is also found in earlier patents by other screw inventors. The first successful implementation of the swashplate was made by de la Cierva in 1922 in his autogyro. [2] In 1907 before the flight test of Cornu's helicopter. Can be seen wheels (plates) with levers controlling the pitch of the propellers.
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 ...
During landing, the reverse happens when the nose-wheel touches the runway and the wing assumes a negative angle of attack with no lift. For aircraft with a tailwheel, the pilot initially pushes forward on the yoke during the takeoff run, lifting the tailwheel off the runway, and the aircraft lifts off the runway once sufficient speed is achieved.
Flying shuttle showing metal capped ends, wheels, and a pirn of weft thread. John Kay (17 June 1704 – c. 1779) was an English inventor whose most important creation was the flying shuttle, which was a key contribution to the Industrial Revolution. He is often confused with his namesake, [10] [11] who built the first "spinning frame". [12]
