The rudder may also be called upon to counter-act the adverse yaw produced by the roll-control surfaces. If rudder is continuously applied in level flight the aircraft will yaw initially in the direction of the applied rudder – the primary effect of rudder. After a few seconds the aircraft will tend to bank in the direction of yaw.

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 rudder pedal is a foot-operated aircraft flight control interface for controlling the rudder of an aircraft. [1] [2] The usual set-up in modern aircraft is that each pilot has a pedal set consisting of a pair of pedals, with one pedal for each foot. Each right and left pedal works together so that one pedal pops out when the other is ...
Adverse yaw is a secondary effect of the inclination of the lift vectors on the wing due to its rolling velocity and of the application of the ailerons. [2]: 327 Some pilot training manuals focus mainly on the additional drag caused by the downward-deflected aileron [3] [4] and make only brief [5] or indirect [6] mentions of roll effects.
Four different rolls, as seen from the pilot's perspective. In both the barrel roll and the rudder roll, the aircraft is at its lowest altitude when the nose is in position one, and at the highest part of the maneuver when the nose is in position five. A maneuver that greatly resembles a tight barrel-roll is the rudder roll.
Diagram of the Wright brothers' 1899 kite, showing wing bracing and strings attached to hand-held sticks used for warping the wing while in flight. The Wright brothers' first powered aircraft, which utilized warping wings. Wing warping was an early system for lateral (roll) control of a fixed-wing aircraft or kite.
The asymmetric lift causes asymmetric drag, which causes the aircraft to yaw adversely. To correct the yaw, the pilot uses the rudder to perform a coordinated turn. In a multi-engined aircraft, the loss of thrust in one engine can also cause adverse yaw, and here again the rudder is used to regain coordinated flight.
