A turboprop airliner is a type of aircraft that uses a turbine engine to drive a propeller. This design combines the efficiency of jet engines with the performance of propellers, making turboprop airliners ideal for short to medium-haul flights. They are commonly used for regional travel, connecting smaller airports to larger hubs. These airliners are known for their ability to take off and land on shorter runways, which allows access to more remote locations. Popular models include the Bombardier Q400 and the ATR 72, both of which are widely used by airlines around the world for regional services.
