About the Edge Aerodynamics 540

The Edge 540 is a high-performance aerobatic monoplane designed by American engineer Leo Loudenslager and refined by Zivko Aeronautics (now Edge Aerodynamics) in the 1990s. Built for unlimited-class aerobatic competition, the 540 features a composite fuselage, symmetrical airfoil, and a powerful Lycoming engine that delivers an exceptional power-to-weight ratio, enabling sustained vertical climbs, knife-edge flight, and snap rolls that have made it a dominant force on the Red Bull Air Race circuit and at world aerobatic championships. The aircraft's short-coupled design and rapid roll rate (over 400 degrees per second) allow pilots to execute complex sequences with precision, though the same characteristics demand constant attention and smooth inputs from less experienced hands.

While purpose-built for competition, the 540 has found a niche among serious aerobatic enthusiasts and airshow performers who value its docile low-speed handling and forgiving stall characteristics alongside its aggressive aerobatic capability. The type's relatively light empty weight keeps it within the reach of owner-operators, and its tandem seating configuration makes it a popular advanced trainer for pilots transitioning into unlimited aerobatics. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
