Aérospatiale/Alenia ATR42 & ATR72
Aérospatiale and Alenia jointly developed the ATR42 commuter aircraft in the 1980s, as a response to the deregulated air transport market in the USA. The 45-50 seat ATR42 was later joined by the longer ATR72. The aircraft can especially be recognised by large vertical stabiliser and associated dorsal fin, with two bents in the leading edge. Other characteristics are the short landing gear, retracting in pods underneath the fuselage, and the pointed tail cone. The latter is also a characteristic of the smaller Dornier 328, with which the ATR42 can be confused.
How to recognise the different versions of the ATR family will be added later.
Confusion possible with
The aircraft that looks most like an ATR42 is the Dornier 328-100 pictured here. It has the same pointy tail cone and short landing gear, but has oval cabin windows and four instead of six cockpit windows. Also note the streamline body on top of the fuselage.
While being of the same size and basic configuration as the ATR, the Dash 8 series can be easily recognised by longer engine nacelles, in which the long main landing gear retracts.
