An aviation term that describes an aerobatic procedure:

A high-thrust maneuver that changes a plane's bearing and increases and altitude. By pitching the nose up and climbing, the aircraft can execute one-half of a loop. This is termintated by inverting and executing a roll. (The amount of roll applied determines your new heading.

This leaves the aircraft flying in a different direction, but at a higher altitude. Once the wings are level, the pilot can perform a half-roll again to reassume a normal flight.
