What is the danger of 'over-controlling' an aircraft?

Over-controlling an aircraft typically refers to the pilot making abrupt or excessive inputs on the flight controls, leading to rapid changes in the aircraft's attitude and altitude. This can result in excessive yaw, which is the side-to-side movement of the aircraft's nose. Yawing can destabilize the aircraft and may cause it to enter a spiral or an uncontrolled state if not managed properly. In many cases, particularly in smaller aircraft like the Cessna 152, over-control can lead to a loss of control, as the aircraft may respond unpredictably to the pilot's actions.

While over-controlling can also have implications for drag, fuel efficiency, and stall conditions, the primary and most immediate danger in the context of basic flight control is indeed the excessive yaw that can compromise stability and lead to a potential loss of control, making that option the most relevant in understanding the risks associated with over-controlling.
