Directions of rotation or pivot possible on a weapon system mounted on the aircraft. Which term describes left-right rotation?

• A. Elevation
• B. Azimuth
• C. Pitch
• D. Roll

Answer: (B)

Left-right rotation is azimuth—the horizontal sweep of the weapon about a vertical axis. It sets where the gun is pointing along the horizontal plane, like turning your turret left or right to aim toward a target. Elevation moves the gun up and down in the vertical plane, changing the angle of shot upward or downward. Pitch is rotation about the aircraft’s lateral axis, tilting the gun up or down along that side-to-side axis, while roll is rotation about the aircraft’s longitudinal axis, tipping the mount as the aircraft banks. So for left-right aiming, azimuth is the correct term.
