Which wing increases drag when the ailerons are moved?
- Both wings increase drag but the wing with the up-going aileron has more.
- Both wings experience an equal increase in drag.
- Both wings increase drag but the wing with the down-going aileron increases more.
Explanation from PART66Online
The down-going aileron raises that wing's lift coefficient, which also raises its induced drag, so the wing with the down-going aileron gains the most drag. This unequal drag yaws the nose away from the turn, the effect known as adverse yaw, which differential ailerons are designed to reduce.

Down going aileron will produce more drag than up going aileron because it has larger projection to the airflow. It also increases curvate of the profile what leads to increased lift, and as result increased induced drag. This effect can cause adverse yaw. To avoid this effect aircraft can be equipped with differential aileron controls or frise ailerons.

thanks.i was thinking normally aircraft are installed with differential aileron but still how could down going wing could have more drag...
