What is the minimum horsepower requirement for an airplane to be categorized as high performance?

To categorize an airplane as "high performance," it must have an engine with more than 200 horsepower. This classification is important because aircraft with high performance engines have specific operational characteristics and piloting requirements. Pilots must hold a high-performance endorsement to operate these aircraft, as they often feature enhanced capabilities compared to lower-powered planes, including higher speeds and different handling characteristics.

The minimum threshold of 200 horsepower establishes a standard that distinguishes high performance airplanes from those that might be simpler to operate. This ensures that pilots are trained and familiar with the complexities that can arise from operating such aircraft, thus enhancing safety and operational proficiency.
