The term for the nose moving up and down relative to the horizon is

• A. Yaw
• B. Pitch
• C. Climb
• D. Roll

Answer: (B)

Pitch is rotation about the aircraft's lateral axis, which runs wingtip to wingtip. When the nose moves up or down relative to the horizon, you’re seeing a pitch motion that tilts the aircraft nose up for climb or nose down for descent. This is different from yaw, which is nose movement left or right around the vertical axis, and from roll, which is the wings tilting up or down around the aircraft’s forward axis. In flight, pitch control is what you use to change your climb or descent, and the attitude indicator shows this pitch relative to the horizon.
