Barrel roll

<p>A <b>barrel roll</b> is an aerial maneuver in which an <a href="/en/Airplane" title="Airplane" class="wl">airplane</a> makes a complete <a href="/en/Rotation" title="Rotation" class="wl">rotation</a> on both its longitudinal and lateral axes, causing it to follow a <a href="/en/Helix" title="Helix" class="wl">helical</a> path, approximately maintaining its original direction.

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 on the object throughout the maneuver, commonly between 2 and 3g, and no less than 0.5g. The barrel roll is commonly confused with an aileron roll.
