  2. Adverse yaw - Wikipedia

    en.wikipedia.org/wiki/Adverse_yaw

    Adverse yaw is the natural and undesirable tendency for an aircraft to yaw in the opposite direction of a roll.It is caused by the difference in lift and drag of each wing. The effect can be greatly minimized with ailerons deliberately designed to create drag when deflected upward and/or mechanisms which automatically apply some amount of coordinated rudde

  3. Flight control surfaces - Wikipedia

    en.wikipedia.org/wiki/Flight_control_surfaces

    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.

  4. Skid (aerodynamics) - Wikipedia

    en.wikipedia.org/wiki/Skid_(aerodynamics)

    Airplane in a right turn skid. In a straight flight, the tail of the airplane aligns the fuselage into the relative wind.However, in the beginning of a turn, when the ailerons are being applied in order to bank the airplane, the ailerons also cause an adverse yaw of the airplane.

  5. Flight with disabled controls - Wikipedia

    en.wikipedia.org/wiki/Flight_with_disabled_controls

    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.

    "In Dutch roll, the aircraft experiences a rolling motion primarily driven by the design (dihedral effect) of the wings, while simultaneously yawing due to the adverse yaw effect caused by the ...

  7. Spoiler (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Spoiler_(aeronautics)

    Some aircraft use spoilers in combination with or in lieu of ailerons for roll control, primarily to reduce adverse yaw when rudder input is limited by higher speeds. For such spoilers the term spoileron has been coined. In the case of a spoileron, in order for it to be used as a control surface, it is raised on one wing only, thus decreasing ...

  8. Aircraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Aircraft_flight_dynamics

    Applying an impulse via the rudder pedals should induce Dutch roll, which is the oscillation in roll and yaw, with the roll motion lagging yaw by a quarter cycle, so that the wing tips follow elliptical paths with respect to the aircraft. The yaw plane translational equation, as in the pitch plane, equates the centripetal acceleration to the ...

  9. Aileron - Wikipedia

    en.wikipedia.org/wiki/Aileron

    Adverse yaw moment is basically countered by aircraft yaw stability and also by the use of differential aileron movement. [39] The Frise-type aileron also forms a slot, so air flows smoothly over the lowered aileron, making it more effective at high angles of attack. Frise-type ailerons may also be designed to function differentially.
