During a 720° steep turn to the right, what is the primary purpose of using the rudder?

1. Prevent yawing

2. Control the rate of turn

3. Hold the aircraft in the turn

The correct answer is: Prevent yawing

In a 720° steep turn to the right, the primary purpose of using the rudder is to prevent yawing. As the aircraft enters a turn, the centrifugal force acting outward and the aircraft's inherent tendency to yaw in the opposite direction must be countered. The use of rudder in this scenario ensures the aircraft maintains coordinated flight, which is crucial during steep turns. When the pilot applies right aileron to initiate and maintain a right turn, the left wing experiences a decrease in lift and consequently less induced drag compared to the right wing. This imbalance can cause the aircraft to yaw to the left, leading to potential unwanted altitude loss or an uncoordinated turn. Using right rudder corrects for this left yawing tendency, allowing the aircraft to turn smoothly and efficiently without slipping or skidding. It also assists in maintaining the desired bank angle while enhancing the overall stability and control of the aircraft during the maneuver, thus making the turn safer and more effective.
