What are the three degrees of motion that illustrate rotation around axes?

• A. Pitch, yaw, and rate
• B. Pitch, roll, and yaw
• C. Roll, pitch, and yaw rate
• D. Roll, yaw, and pitch

Answer: (B)

Rotations in flight are described by three motions about the aircraft’s three axes: pitch, roll, and yaw. Pitch is rotation around the lateral axis that runs wingtip to wingtip, so tilting the nose up or down changes the aircraft’s angle of ascent. Roll is rotation around the longitudinal axis that runs from nose to tail, causing the wings to tilt one side down and the other up. Yaw is rotation around the vertical axis, turning the nose left or right without banking. These three movements together capture the three degrees of rotational motion around the axes, which is why this trio is the correct answer. Options that include “rate” refer to how fast the rotation occurs (angular velocity), not the actual rotation about an axis, so they describe speed rather than the direction of rotation.
