During a roll, what action is required to counteract adverse yaw?

Apply rudder to counteract adverse yaw. Increase pitch attitude to counteract yaw. Use ailerons only; no rudder. Reduce power and retract flaps.

Correct Answer:

Apply rudder to counteract adverse yaw.

Explanation:

When you roll, using the ailerons creates a drag difference between the wings, so the nose tends to yaw opposite the direction you’re rolling. To keep the turn coordinated, you add a bit of rudder in the same direction as the roll. This rudder input cancels the yawing moment caused by the unequal drag, letting the airplane roll smoothly without slipping its nose out of alignment. The other options don’t address the yaw caused by differential drag: increasing pitch doesn’t fix yaw, using only the ailerons adds yaw, and changing power or flaps changes thrust/drag but not the yaw moment from the roll.
