Zivko Edge 540
The Zivko Edge 540 is a high‑performance aerobatic single‑seater produced by Zivko Aeronautics of Wichita, Kansas. Development began in the early 1990s when designer William Zivko sought a purpose‑built aircraft capable of extreme maneuvers for competition and air‑show work. The prototype flew in 1996 and the type quickly earned a reputation for agility, leading to its selection by the United States Air Force Thunderbirds and numerous national champions.
Key features include a carbon‑fiber monocoque fuselage, a 260‑horsepower Lycoming AEIO‑540 engine, and a compact, symmetrical airfoil wing with a 7‑meter span that produces exceptionally low roll inertia. The aircraft’s control surfaces are oversized and hinged on push‑rod linkages, delivering instantaneous response throughout a ±15‑g envelope. A fully retractable landing gear reduces drag, while the cockpit is equipped with advanced telemetry and a dual‑axis stick for precise input.
The Edge 540’s significance lies in setting new standards for aerobatic performance and safety. Its dominance in world championship events has inspired a generation of pilots and designers, cementing Zivko Aeronautics as a cornerstone of modern aerobatics and influencing subsequent composite‑constructed sport aircraft worldwide. Today the Edge 540 continues to be a benchmark for performance, regularly flown in international displays and training programs worldwide.
