A turboprop is a type of aircraft propulsion system that uses a gas turbine engine to drive a propeller. This design combines the efficiency of a jet engine with the thrust of a propeller, making it suitable for short to medium-haul flights. Turboprop engines are commonly found in regional and commuter aircraft, providing good fuel efficiency at lower speeds. Turboprop engines are often used in smaller planes, such as those manufactured by Bombardier and ATR. They are particularly effective for flying shorter distances, as they can take off and land on shorter runways compared to pure jet engines.
