Turboprop, twin-engine ATR 42, is the regional aircraft designed primarily for passenger transport on short in routing. Final assembly of the aircraft ATR 42, like the Airbus, made in Toulouse.

The program for the development of ATR 42, was officially opened in October 1981 years.

As the concept of the aircraft, the design of a twin-engine monoplane was chosen, with a high-lying, elongated wing of a trapezoidal shape and a "T" -shaped tail unit. The first prototype aircraft was designated ATR-42-200, This modification was built for testing purposes and was not released serially. The wing of the aircraft and the engine nacelles were designed by the now abolished French, aerospace engineering company, Aerospatiale. The length of the wing of the aircraft is equal to 24,57 meters. Such a wingspan, with an overall length of an airplane of 22,67 meters, allows it to remain as stable as possible at low flight speeds, for example during a landing approach. Under the wings of the first prototype, ATR-42, turbo-prop engines Pratt & Whitney Canada PW120, powered by 1800 hp, were used as powerplant. The aircraft was equipped with a three-column retractable landing gear, for which the French company Messier Hispano Bugatti. "

It allows you to transport 42 passengers at a distance of 1500 kilometers with an average speed of 450 kilometers per hour. This modification was produced before 1996 year, after which it was withdrawn from production, but is still in operation. Improving the version of ATR 42-300, there are two of its modifications. The first modification - ATR 42-320, which received engines Pratt & Whitney Canada PW121 power 2100 hp The second modified version, designated as ATR 42-400, had engines that were previously installed on the 42-320 ATR, but with a six-blade propeller.

In the cabin of the airplane new, comfortable and lighter passenger seats are installed. The aircraft's flight indices also became much higher. The cruising speed of the new machine is 556 kilometers per hour. It is capable of carrying up to 52 passengers for an average distance of 1555 kilometers. ATR 42-600, is equipped with the latest avionics and navigation equipment, which includes five multifunction LCD monitors for displaying all flight information, and a multipurpose computer MPC (Multi-Purpose Computer). This contributes to the convenience of management, and hence to further improve flight safety.
