Azerbaijan Airlines (Azerbaijani: Azərbaycan Hava Yolları), also known as AZAL, is the flag carrier of Azerbaijan, as well as the largest airline. Based in Baku, adjacent to Heydar Aliyev International Airport, the carrier operates a fleet of 30 aircraft to 57 destinations across Asia, the CIS, Europe and the USA. Azerbaijan Airlines is a member of the International Air Transport Association (IATA).
The city of Nakhchivan (Azerbaijani: Naxçıvan) is the capital of the eponymous Nakhchivan Autonomous Republic of Azerbaijan, located 450 km (280 mi) west of Baku. The municipality of Nakhchivan consists of the city of Nakhchivan and the villages of Başbaşı, Qarağalıq, and Daşduz. It is spread over the foothills of Zangezur Mountains, on the right bank of the Nakhchivan River at an altitude of almost 1,000 m (3,300 ft).
The Boeing 757 is a mid-size, narrow-body twin-engine jet airliner that was designed and built by Boeing Commercial Airplanes. It is the manufacturer's largest single-aisle passenger aircraft and was produced from 1981 to 2004. The twinjet has a two-crew member glass cockpit, turbofan engines, a conventional tail and, for reduced aerodynamic drag, a supercritical wing design. Intended to replace the smaller three-engine 727 on short and medium routes, the 757 can carry 200 to 295 passengers for a maximum of 3,150 to 4,100 nautical miles (5,830 to 7,590 km), depending on variant. The 757 was designed concurrently with a wide-body twinjet, the 767, and owing to shared features pilots can obtain a common type rating that allows them to operate both aircraft.
The 757 was produced in two fuselage lengths. The original 757-200 entered service in 1983; the 757-200PF, a package freighter (PF) variant, and the 757-200M, a passenger-freighter combi model, debuted in the late 1980s. The stretched 757-300, the longest narrow-body twinjet ever produced, began service in 1999. Passenger 757-200s have been modified to special freighter (SF) specification for cargo use, while military derivatives include the C-32 transport, VIP carriers, and other multi-purpose aircraft. Private and government operators have also customized the 757 for research and transport roles. All 757s are powered by Rolls-Royce RB211 or Pratt & Whitney PW2000 series turbofans.
