About the ATR 42-500

The ATR 42-500 is a twin-turboprop regional airliner built by the French-Italian consortium ATR, introduced in 1995 as an upgraded variant of the original ATR 42 family that first flew in 1984. Powered by two Pratt & Whitney Canada PW127E engines driving six-blade propellers, the -500 series brought significant improvements in cabin comfort, avionics, and hot-and-high performance over earlier models, making it particularly popular for short-haul routes in challenging environments. The type seats 42-50 passengers and excels in the 200-500 nautical mile range segment, where its fuel efficiency and ability to operate from short, unpaved runways give it a decisive advantage over jets.

The ATR 42-500 cruises at around 300 knots and can reach altitudes up to 25,000 feet, though it typically operates lower to optimize turboprop efficiency. Its maximum operating speed of 250 knots IAS and approach speed around 100 knots make it well-suited for smaller regional airports with limited infrastructure. The aircraft's STOL capability—requiring as little as 3,400 feet of runway—has made it a workhorse for operators serving remote communities in northern Canada, the Caribbean, and island nations worldwide. With a maximum takeoff weight just over 41,000 pounds, it falls into ICAO's Medium wake turbulence category.

The type remains in production today as part of ATR's current lineup, competing primarily against the Bombardier Dash 8 series in the regional turboprop market. Its low operating costs, typically 30-40% lower than comparable regional jets on short sectors, have sustained strong demand from carriers focused on thin routes and essential air services. The ATR 42-500's reputation for reliability in harsh climates—from Arctic operations to tropical island-hopping—has cemented its role as the backbone of regional connectivity in underserved markets. SkyMeter has tracked flights across airframes and operators over routes, with the largest observed operator.
