The Lycoming O-540 is a family of air-cooled six-cylinder, horizontally opposed fixed-wing aircraft and helicopter engines of 541.5 cubic inch (8,874 cc) displacement, manufactured by Lycoming Engines. The engine is a six-cylinder version of the four-cylinder Lycoming O-360.

Design and development

Producing between 230 and 350 horsepower (170 and 260 kW)[1] these engines are installed in a large variety of aircraft.[2] The main competitors are the Continental IO-520 and IO-550 series.

An AEIO version was developed for high-performance competition aerobatics aircraft. Starting at 260 hp (190 kW) the power was eventually increased to 300 hp (220 kW). The AEIO-540 family has achieved considerable success in aircraft such as the Extra 300, CAP 232, and Zivko Edge 540.

Variants

All engines have an additional prefix preceding the 540 to indicate the specific configuration of the engine.[1] The numerous engine suffixes denote different accessories such as different manufacturers' carburetors, or different magnetos.
