Which propeller aircraft cruise at 250 knots?

The ATR 42/72 and the Jetstream 41 are propeller-driven aircraft that have a typical cruising speed around 250 knots, which places them at the higher performance end of regional and commuter aircraft. The ATR series, particularly, is designed for regional airline service and is known for its efficiency and ability to operate at relatively high speeds for turboprop aircraft. Similarly, the Jetstream 41 is a high-speed commuter aircraft, which can also achieve cruising speeds close to or at this threshold.

Aircraft like the Dash 8, Beechcraft 1900D, and Piper Navajo tend to cruise at lower speeds, typically between 150 to 200 knots, making them more suitable for smaller regional flights or general aviation use. Consequently, their operational characteristics and design limitations prevent them from achieving the higher cruising speeds demonstrated by the ATR and Jetstream 41. Thus, the choice of the ATR 42/72 and Jetstream 41 aligns with the question regarding propeller aircraft that can maintain cruise speeds of 250 knots.
