Which of the following represents the three primary rotational movements of an aircraft about its axes?

• A. Yaw
• B. Roll
• C. Pitch
• D. All of the above

Answer: (D)

Rotations of an aircraft about its axes describe how its orientation changes in three ways. The aircraft rolls when it rotates about its longitudinal axis, which runs from nose to tail. It pitches when it rotates about its lateral axis, which runs wingtip to wingtip. It yaw’s when it rotates about its vertical axis, which runs top to bottom. Put together, the three primary rotational movements are roll, pitch, and yaw. Each movement is controlled by a different control surface—ailerons for roll, the elevator for pitch, and the rudder for yaw—so recognizing all three together is essential. Since only one option mentions all three movements, it is the best choice. The other options capture only a single motion, not the complete set.
