Quick Summary

A half-roll is an aerial maneuver where an airplane rotates halfway around its longitudinal axis, resulting in it flying upside down along its original flight path. This maneuver is performed using the ailerons, which are movable parts on an airplane's wing that allow the pilot to control the aircraft's roll. Unlike a full aileron roll, which completes a 360-degree rotation, a half-roll intentionally stops at the inverted position. An airplane can also be described as performing a half-roll.1234
