engines, yielding significant gains in fuel economy and a reduction in noise, but also posing an engineering challenge given the low ground clearance of the 737 – a trait of its 707-derived fuselage. Boeing and engine supplier CFM International solved the problem by placing the engine ahead of (rather than below) the wing, and by moving engine accessories to the sides (rather than the bottom) of the engine pod, giving the 737 a distinctive noncircular air intake. The wing incorporated a number of changes for improved

A further stretched model, the 737-400, was launched with an order for 25 aircraft with 30 options from

in June 1986. That aircraft first flew in February 1988 and entered service later that year with Piedmont Airlines. The final model of the series, the 737-500, was launched with an order for 30 aircraft from Southwest Airlines in May 1987. That aircraft, which was designed as a replacement for the 737-200 and had similar passenger capacity and dimensions, as well as the longest range of any member of the 737 Classic family, first flew in June 1989 and entered service with Southwest Airlines in 1990.


Engines

Boeing selected the CFM56-3 exclusively to power the 737-300 variant. The 737 wings were closer to the ground than previous applications for the CFM56, necessitating several modifications to the engine. The fan diameter was reduced, which reduced the bypass ratio, and the engine accessory gearbox was moved from the bottom of the engine (the 6 o'clock position) to the 9 o'clock position, giving the engine nacelle its distinctive flat-bottomed shape, which is often nicknamed the "hamster pouch". The overall thrust was also reduced, from , mostly due to the reduction in

Speed Trim System

The 737 Classic saw introduction of Speed Trim System (STS), a flight augmentation system that adjusts the stabilizer automatically at low speed, low weight, aft center of gravity and high thrust with autopilot disengaged. Most frequently it can be observed during takeoffs and go-arounds. The system relies on most of the same hardware and software used in autopilot mode. STS is not fail-safe in that it uses only one of each sensor types required for its functionality and a single computer. Such a single-channel design is not common for augmentation systems that have full control of the stabilizer. This design was considered acceptable because of the ability for the aft and forward column cutout switches as well as center console cutout switches to constrain its malfunction. The limited flight envelope protections on the 737 Next Generation series, as well as MCAS on the 737 MAX, are later extensions of this system.


Further developments

Throughout the 1980s, the 737 Classic series attracted large orders from airlines in the United States and Europe, with its order totals exceeding those of preceding 737 models. By far, the most successful model was the 737-300, with deliveries totaling 1,113 aircraft (the 737-400 and -500 reached 486 and 389 deliveries, respectively). Major operators included US carriers, small national airlines, and charter carriers. By the 1990s, when regular Boeing customer

, this prompted Boeing to update the slower, shorter-range 737 Classic -400 into the rewinged, updated, more efficient, longer 737NG-800. Production of the 737 Classic continued alongside that of the Next Generation for a period of time; the first 737-700 was completed in December 1996; the last 737 Classic was completed in February 2000.

Variants


737-300

The prototype of the -300 rolled out of the Renton plant on January 17, 1984, and first flew on February 24, 1984. After it received its flight certification on November 14, 1984, USAir received the first aircraft on November 28. It proved a very popular aircraft: Boeing received 252 orders in 1985, and over 1,000 throughout its production. The 300 series remained in production until the last aircraft was delivered to

In November 2018, VX Capital launched an ABS secured on 35 737-400 freighters valued at $250 million (an average of $ million), to be leased for $100,000 per month each.


737-500

The -500 series has the smallest dimensions of the 737 Classics. The -500 was offered, due to customer demand, as a modern and direct replacement of the 737-200, incorporating the improvements of the 737 Classic series in a model that allowed longer routes with fewer passengers to be more economical than with the 737-300. Though smaller than the -300 and -400, the fuselage length of the -500 is longer than the 737-200, accommodating up to 140 passengers. Both glass and older style mechanical cockpits arrangements were available. Using the CFM56-3 engine also gave a 25% increase in fuel efficiency over the older -200s P&W engines. The 737-500 was launched in 1987, by Southwest Airlines, with an order for 20 aircraft, and flew for the first time on June 30, 1989. A single prototype flew 375 hours for the certification process, and on February 28, 1990 Southwest Airlines received the first delivery. The 737-500 has become a favorite of some Russian airlines, with Nordavia,

As the retirement of all 737 Classic models progressed, with retirement of 300s and -500s reaching 40% in 2012, the 737-500 has faced accelerated retirement because of its smaller size. Aircraft of this series were being retired after 21 years of use, as compared to 24 years for the 737-300. While a few 737-300s are slated for freighter conversion, no demand at all exists for a -500 freighter conversion.
