Design and development
editProducing 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 theContinental IO-520andIO-550series.
An AEIO version was developed for high-performancecompetition aerobaticsaircraft. 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 theExtra 300,CAP 232,andZivko Edge 540.
Variants
editAll 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 differentmagnetos.
