The "Split S" is an aerobatic maneuver commonly used in aviation, particularly in aerobatic flying and military training. It involves a half roll followed by a descending turn, allowing the aircraft to change direction while losing altitude. This maneuver is often performed to evade threats or reposition during aerial combat. To execute a Split S, the pilot begins by rolling the aircraft upside down and then pulls back on the control stick to initiate a descent. This technique requires precise control and awareness of the aircraft's speed and altitude, making it a valuable skill for pilots in fighter jets and airshows.
