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
Inverted spinning and erect or upright spinning are dynamically very similar and require essentially the same recovery process but use opposite elevator control. In an upright spin, both roll and yaw are in the same direction, but an inverted spin is composed of opposing roll and yaw. It is crucial that the yaw be countered to effect recovery.
For main rotors with counter-clockwise rotation, that is wind from 9 o'clock. Analysis of flight test data verifies that the tail rotor does not stall. The helicopter will exhibit a tendency to make a sudden, uncommanded yaw that will develop into a high turn rate if not corrected.
On aircraft with propellers that rotate counter-clockwise, such as the de Havilland Dove, the right engine would be the critical engine. Most aircraft that have counter-rotating propellers do not have a critical engine defined by the above mechanism because the two propellers are made to rotate inward from the top of the arc; both engines are ...
The yaw motion is induced through the use of ailerons alone due to aileron drag, wherein the lifting wing (aileron down) is doing more work than the descending wing (aileron up) and therefore creates more drag, forcing the lifting wing back, yawing the aircraft toward it. This yawing effect produced by rolling motion is known as adverse yaw.

Attack therapy is one of several pseudo-therapeutic methods described in the book Crazy Therapies. It involves highly confrontational interaction between the patient and a "therapist" or between the patient and fellow patients during group therapy , in which the patient may be verbally abused, denounced, or humiliated by the therapist or other ...
