✈️All maneuvers are done based on different combinations of primary flight movement including Roll, Pitch and Yaw.
...
👨🏻✈️Aircraft moves along three axes of rotation.
✈️Longitudinal Axes: Extends from nose to tail
✈️Lateral Axes: Extends from one wingtip to another wingtip
✈️Vertical Axes: Passes vertically through the center of gravity
...
👨🏻✈️What is the primary flight control on the aircraft?
✈️Aileron (Roll): By turning the yoke or joystick
✈️Elevator (Pitch): By pulling or pushing the yoke or joystick
✈️Rudder (Yaw): By stepping the rudder pedal

Hello~
The Secondary Effect of aileron 會有adverse yaw. 當introduce roll to the left, aircraft with yaw to the right~ (thats becoz of the right aileron deflects down and more life(drag) acting on the right wing.)
So you might able feel the air yaw to the opposite side.
Of coz, the Relative wind will hit the aft fuselage and realign the directional control.
Thats related to directional stability.
In conclusion, the adverse yaw will lead the aircraft yaw to opposite side of the roll. On Aircraft with strong directional stability will minimize the yaw and realign the aircraft to RAF.
Got it?~
你好，想請教下Secondary effect of aileron 就係yaw 因為sideslip, RAF hit CG aft fuselage, 但roll同時又有adverse yaw, 咁究竟roll left 時，係yaw 去right 定left, 謝謝
