The yaw axis has its origin at the center of gravity and is directed towards the bottom of the aircraft, perpendicular to the wings and to the fuselage reference line. Motion about this axis is called yaw. A positive yawing motion moves the nose of the aircraft to the right. [1] [2] The rudder is the primary control of yaw. [3]
The rudder is a fundamental control surface which is typically controlled by pedals rather than at the stick. It is the primary means of controlling yaw—the rotation of an airplane about its vertical axis. The rudder may also be called upon to counter-act the adverse yaw produced by the roll-control surfaces.
The body rate r is made up of the rate of change of sideslip angle and the rate of turn. Taking the latter as zero, assuming no effect on the trajectory, for the limited purpose of studying the Dutch roll: = The yaw and roll equations, with the stability derivatives become:
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 ...
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. Coordinated flight requires the pilot to use pitch, roll and yaw control simultaneously. See also flight dynamics.
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.

Collection of control yokes at Boeing Future of Flight Museum: 747, 707, B-29, Trimotor.The former two yokes are W-shaped, while the latter two are circular. The cockpit of Concorde, which has an M-shaped yoke mounted on a control column The cockpit of an Embraer ERJ with an M-shaped yoke "W"/"U" style yoke in a Cessna 152 light aircraft, mounted on a horizontal tube protruding from the ...
The cockpit of a Slingsby T-67 Firefly two-seat light airplane.The flight instruments are visible on the left of the instrument panel. Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in flight.
