What is the typical speed range for turboprop engines?

Turboprop engines are commonly found in regional and commuter aircraft, where their operating speeds typically range from 200 to 300 knots. This range is reflective of the efficiency and performance characteristics of turboprop engines, which are designed to provide good fuel economy and the ability to take off and land on shorter runways.

Turboprop engines are particularly suitable for flights that involve lower altitudes and shorter distances, making their speed range optimal for regional travel. Speeds below this range (like those mentioned in the first choice) are generally associated with light aircraft or specific types of general aviation aircraft, which do not fall within the turboprop category. Similarly, speeds above the 300 knots range are characteristic of turbojet or turbofan engines, typically found in larger commercial jets designed for faster, longer hauls. Thus, the selection of 200 to 300 knots accurately describes the operational speeds of turboprop aircraft.
