High G Barrel Roll

High G Barrel Roll

A high-g barrel roll is a combination of a loop and a snap roll. A high g barrel roll is a last-ditch defensive maneuver, performed when the attacker has achieved a suitable guns solution, in order to cause an overshoot. The high-g barrel roll is a violent maneuver which is performed much more aggressively than a normal barrel roll. Range is critical to the success of the roll, and the defender will usually turn very hard, or employ other measures to draw the opponent very close before performing the roll. The roll is executed by applying hard back-stick pressure, creating the high g-forces, and adding hard rudder input to assist the ailerons in rolling the fighter. A high-g barrel roll can be performed "over-the-top", or it can be performed "underneath", which is accomplished by rolling upside-down and beginning the maneuver from the inverted position. The high-g barrel roll is an energy-depleting maneuver that rarely causes the attacker to fly out in front, but usually will result in a flight path overshoot, a flat scissors, or, at the very least, will temporarily disrupt the attacker's aim.
