A barrel roll is an aerial maneuver in which an airplane makes a complete rotation on both its longitudinal and lateral axes, causing it to follow a helical path, approximately maintaining its original direction. It is sometimes described as a "combination of a loop and a roll." The g-force is kept positive (but not constant) on the object throughout the maneuver, commonly between 2–3 g, and no less than 0.5 g.
