A single or single-engine aircraft is a aircraft powered by one engine.
Both twin-engine and single-engine piston aircraft are well-suited for short missions under 300 miles. They can easily access smaller airports with shorter runways, increasing the number of airstrips they’re able to reach within their ranges. The second engine increases an aircraft’s payload and speed. In addition to faster cruise speeds, the added horsepower of a second engine also improves takeoff and climb performance.
