The Boeing 737-500 is a passenger aircraft for short and medium-haul airlines. It is the youngest model of the “classic” Boeing 737 series (737-300 / 400/500), which was mass-produced in 1990-1999.
In 1983, Boeing launched the development of a 100-seat 737-250 aircraft, which would occupy a market place in terms of capacity between the 737-100 and 737-200 aircraft. The Boeing 737-500 is a shortened version of the 737-300 with an increased range. With a fuselage longer than the 737-200, half a meter, the Boeing 737-500 was an excellent replacement for it. The main competitor was the 115-seat Fokker 100, which was being designed by Fokker at the time.
In 1986, Boeing ceased operations on the 737-250 aircraft and concentrated all its efforts on the 737-400 project. The reason for this decision was that the American Pacific Southwest and U.S. Air Airlines preferred British Aerospace BAe 146 and Fokker 100 to Boeing.
In January 1988, it became clear that the operation of the 737-200 aircraft, which did not meet the new noise standards, would be severely limited. The Boeing company again began to talk about the version of the aircraft with CFM56 engines, but already as a direct replacement of the 737-200 aircraft. The project, designated 737-500, was designed to transport 132 passengers in the economy class, which is 15% more than the previously proposed aircraft.
The development of the Boeing 737-500 began in May 1987 after receiving 73 orders. Ultimately, an aircraft with CFM56 engines were developed, replacing the 737-200. One of the greatest technical achievements of this model is the development of dynamic turbojet engines. Thanks to this technology, only a small stream of air captured by the turbine blades enter the main turbine. The main airstream flows around the turbine, absorbing the sound of the jet stream at the output and significantly reducing the noise level. This effect, which reduces the impact of engines on the environment, increases comfort inside the aircraft.
The noise level generated by these engines is significantly lower than the maximum permissible values provided for in Stage 3 of the ICAO Convention. It is also lower than the noise floor stipulated for Stage 4. Due to its high fuel efficiency and relatively low capacity, this type of aircraft is optimal for flights on short and medium-haul lines, including low passenger traffic.
Flight tests of the prototype aircraft began on June 30, 1989. In mid-February 1990, it received the FAA certificate, and at the end of this month, Southwest Airlines received the first aircraft.
The aircraft is designed to carry 104 passengers: 96 people in the economy class cabin and 8 in the business class cabin. The Boeing 737-500 has a spacious cabin, low noise in the cabin, and other advantages that allow for a comfortable flight on board this aircraft.
The aircraft uses the EFIS digital avionics system of the American company “Honeywell” with six flat, color, multifunctional, liquid crystal displays. It is possible to install a GPS satellite navigation system.
On February 15, 1991, the German airline Lufthansa received another 737-500 aircraft, which became the 2000th in the 737 families of aircraft since December 1967. The aircraft has been in serial production since 1990. As of 01.01.1997, 7 aircraft were operated in Russia Boeing 737 (the beginning of operation – 1993).
As noted in the Russian branch of the Boeing company: – “Passengers like Boeing 737 airliners. They are comfortable and very reliable, which ensures the high accuracy of the flight schedule. Airlines, in turn, give preference to this model, because it has a very low level of operating costs. Also, the Boeing 737’s universal advantage is its low noise and emissions. ”
According to the magazine MRO Management, for 2010 in the world park in operation, there are 386 Boeing 737-500.
