SEP (Single Engine Piston)

A Single Engine Piston (SEP) aircraft is a small airplane powered by one piston engine, similar to car engines but designed for aviation. It typically uses aviation fuel to turn a propeller, providing the necessary thrust for flight. SEPs are commonly used for personal, training, or short-distance travel due to their simplicity, cost-effectiveness, and ease of handling. They are ideal for pilots learning to fly or experienced pilots needing versatile, reliable transportation. The single engine means that if the engine fails, the pilot must rely on skills to glide and land safely, emphasizing the importance of maintenance and vigilant operation.
