Single-engine planes are aircraft that have one engine, which provides the necessary power for flight. These planes are commonly used for personal travel, flight training, and recreational flying. Their simpler design makes them generally easier to operate and maintain compared to multi-engine aircraft. Many single-engine planes, like the Cessna 172 or Piper PA-28, are popular among pilots due to their reliability and efficiency. They typically have a smaller wingspan and can land on shorter runways, making them suitable for flying to smaller airports. These planes are often used for scenic flights and are a great way to experience flying.
