The 737-300 is a second-generation stretched version of the 737 family of airplanes and is 109 ft 7
in long. Two sections were added to the 737-200 fuselage; a 44-in section forward of the wing and a
60-in section aft of the wing. Wing and stabilizer spans are also increased. The 737-300
incorporates new aerodynamic and engine technologies in addition to the increased payload and
range. The -300 can seat as many as 149 passengers in an all-economy configuration.
The 737 is a twin-engine airplane designed to operate over short to medium ranges from sea level
runways of less than 6,000 ft (1,830 m) in length.
Significant features of interest to airport planners are described below:
Underwing-mounted engines provide eye-level assessability. Nearly all system maintenance
may be performed at eye level.
Optional airstairs allow operation at airports where no passengers loading bridges or stairs
are available.
Auxiliary power unit can supply energy for engine starting, air conditioning, and electrical
power while the airplane is on the ground or in flight.
Servicing connections allow single-station pressure fueling and overwing gravity fueling.
All servicing of the 737 is accomplished with standard ground equipment.
Boeing announced it was developing the 737-300 in March 1981. This new variant started off as a simple stretch over the 737-200 but Boeing decided to adopt the CFM International CFM56 high bypass turbofan to reduce fuel consumption and comply with the then proposed International Civil Aviation Organisation Stage 3 noise limits.
Despite the all new engines and the 2.64m (104in) fuselage stretch, the 737-300 retains 80% airframe spares commonality and shares the same ground handling equipment with the 737-200. A number of aerodynamic improvements were incorporated to further improve efficiency including modified leading edge slats and a new dorsal fin extending from the tail. Another feature was the flattened, oval shaped engine nacelles, while the nosewheel leg was extended to increase ground clearance for the new engines. Other internal changes include materials and systems improvements first developed for the 757 and 767 programs, including an early generation EFIS flightdeck (with four colour CRT screens).
The 737-300 flew for the first time on February 24 1984, while first deliveries were from November 1984. Since that time well over 1000 737-300s have been sold and it forms the backbone of many airlines' short haul fleets.
