Operational Context

ATR 42-500 — regional turboprop airliner

The ATR 42-500 first flew in 1994 and entered service in 1995. It incorporated upgraded engines and avionics compared with earlier models. The high-wing configuration supports reliable operation at smaller airports.

Two Pratt & Whitney Canada PW127E turboprop engines producing approximately 2,400 shaft horsepower each power the aircraft. Cruise speed approaches 300 knots (556 km/h). Maximum takeoff weight exceeds 41,000 pounds (18,597 kg), with seating typically around 48 passengers.

The ATR 42-500 has served regional airlines globally. Its efficiency and low operating cost make it suitable for short sectors. Many aircraft remain active in commuter fleets.
