ATR42 and ATR72 Quick overview
The ATR is produced between a co-operation of Aerospeciale (France) and Alenia (Italy), and is a high-wing twin turboprop aircraft. Normally considered extremely fuel efficient and often related to as a "Work-horse" it is not surprising that it has been chosen as the number one regional aircraft in the industry.
The first ATR produced for production was the 42-300, which was "adopted" by Air Littoral, Eurowings, Finnair and Cimber Air as the pioneers for this turboprop aircraft.
The ATR42 is a smaller version of the ATR72, and as seen below it has been produced in different models over the years. The latest one is the -600, is an upgrade of the extremely popular -500.
Engines are PRATT and WHITNEY and propellers are UTC (Hamilton and Ratier).

ATR42 technical information
ATR72
The ATR-72 is manufatured, as the ATR42 by Aerospatiale from France and Alenia from Italy.
The ATR 72 is derived from ATR42, with its fuselage extended by 4.5 meters to increase the passenger capacity 64-72 seats (ATR42 has capacity only 42-52 seats).
ATR-72 aircraft flew for the first time on October 27 1988, followed by the awarding of French and then US certification in late 1989. Entry into service was on October 27, 1989
Compared to the ATR72-200 productivity of the ATR 72-500 is improved as the result of increase engine power,significantly extending the payload and range capability.
The ATR72-500 can easily be identified by its new 6 blades propeller.with a reduced diameter and slower rotational speed. The Hamilton Standard/Ratier-Figeac 568 F propellers reduced the noise and vibration transmitted to the passenger cabin.
The ATR72-500 is powered by two Pratt & Whitney Canada PW127F/M
The ATR72-600 is a major visual improvement of the -500. Not only has the cockpit undergone a major change (Glass cockpit), but also the cabin has been improved.
