Yaw string used in front of the cockpit of an F-14D Tomcat. In flight, pilots are instructed to step on the head of the yaw string; the head is the front of the string, where the string is attached to the aircraft. If the head of the yaw string is to the right of the yaw string tail, then the pilot should apply right rudder pressure.
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 ...
ALT1 may be entered if there are faults in the horizontal stabilizer, an elevator, yaw-damper actuation, slat or flap sensor, or a single air data reference fault. [ 7 ] Alternate law 2 (ALT2) loses normal law lateral mode (replaced by roll direct mode and yaw alternate mode) along with pitch attitude protection, bank angle protection and low ...
Using ailerons causes adverse yaw, meaning the nose of the aircraft yaws in a direction opposite to the aileron application. When moving the aileron control to bank the wings to the left, adverse yaw moves the nose of the aircraft to the right. Adverse yaw is most pronounced in low-speed aircraft with long wings, such as gliders.
Yaw – in which the nose of the airplane moves left or right. This is typically controlled by the rudder at the rear of the airplane. Roll (bank) – in which one wing of the airplane moves up and the other moves down. This is typically controlled by ailerons on the wings of the airplane.
A winglet on a KC-135 Stratotanker with attached tufts showing airflow during NASA tests in 1979–80.. In aeronautics, tufts are pieces of yarn or string, typically around 15 cm (6 in) long, attached to an aircraft surface in a grid pattern and imaged during flight.
With a symmetrical rocket or missile, the directional stability in yaw is the same as the pitch stability; it resembles the short period pitch oscillation, with yaw plane equivalents to the pitch plane stability derivatives. For this reason, pitch and yaw directional stability are collectively known as the "weathercock" stability of the missile.
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.
