Adverse Yaw
Tags: Flying
A condition of flight in which the nose of an airplane tends to yaw toward the outside of the turn. This is caused by the higher induced drag on the outside wing, which is also producing more lift.
Adverse Yaw
Adverse aileron yaw is caused by the down going aileron creating more drag than the up going aileron which in turn causes the aircraft to yaw in the opposite direction to which you want to turn.
Adverse Yaw - Yaw generated when the ailerons are used. The lifting wing generates more drag, causing an airplane to yaw (or turn) toward it.
Adverse yaw The tendency of an aircraft to yaw in the opposite direction of aileron control input.

During the time that the ailerons are activated, an unwanted effect occurs. In the left turn shown above the pilot turns the control wheel to the left, raising the left aileron, and lowering the right aileron.
Adverse yaw in the Citabria is not nearly as noticeable as in a Champ, but it is very definitely there. It's a good compromise in that area.
The dependence of adverse yaw on airspeed can lead to trouble. Pilots spend almost all of their time buzzing around at cruise airspeeds, where ignoring the rudder is OK or nearly so. Sometimes this leads to complacency.
This is done to compensate for the adverse yaw that results from the use of ailerons. Further, to prevent the aircraft from continuing to roll, the pilot must use opposite ailerons in order to maintain the angle of bank that is desired.
Remember, the main purpose of rudder is to compensate for a lowered aileron's adverse yaw, which tends to move the nose opposite the direction you desire to turn. So, simultaneously apply aileron and rudder in the direction you want to turn.
Ailerons and rudder are not interconnected, and when banking into a turn, the nose will yaw opposite the direction of the turn (adverse yaw) unless positive rudder control is exercised. Control cables are stainless steel for corrosion protection.
