Boeing 737-500 vs. ATR 42-600

The Boeing 737-500, introduced in 1987 as part of the 737 Classic series, is a narrow-body, twin-engine airliner designed for short to medium-haul routes. Recognized for its compact size and efficiency, the 737-500 catered to airlines needing a smaller capacity jet with the performance qualities of the larger 737 models.

At 101.7 feet (31.0 meters) in length and with a wingspan of 94.5 feet (28.8 meters), the 737-500 was adept at serving routes that required flexibility for airport size and range. This aircraft was particularly appealing to airlines for its ability to operate efficiently on shorter and less dense routes, providing a practical solution for smaller markets. While the -400 expanded on the -300, the -500 was actually constructed to considerably smaller than the -300. Comparatively, the 737-500 is closest in size and capacity to the 737-200. Powered by two CFM International CFM56-3C1 engines, the Boeing 737-500 has a total thrust capability of 40,000 lbf (178.0 kN). With a fuel capacity of 5,310 US gallons (20,100 liters), it boasts a range of 2,376 nautical miles (4,400 kilometers). The 737-500's cruise speed of 495 mph (796 km/h) contributed to its reputation as a reliable and efficient aircraft for regional travel.

In the commercial aviation landscape of its time, the Boeing 737-500 was a competitor to aircraft like the McDonnell Douglas MD-80 series. Its introduction provided airlines with a versatile option in the 737 family, bridging the gap between the larger 737 models and the need for a more economical, smaller jet. Southwest Airlines was the first customer of the -500, making their first flight in 1989. Lufthansa, United Airlines, and Continental also operated the Boeing 737-500. The aircraft played a significant role in these fleets, enabling the expansion of domestic and regional networks.

The Boeing 737-500 has faced accelerated retirement due to its smaller size. A majority of models were out of service after just 21 years in service. Most freight companies didn't even have interest in turning the -500 into a cargo jet. The 737-500 was replaced by the 737-600 of the Next Generation series.

The ATR 42-600 is a twin-engine, turboprop aircraft is designed for regional travel. Its role in the aviation industry focuses on connecting regional and remote areas, making air travel accessible to smaller communities. The ATR 42 is most recognizable by its high-wing design , T-tail, and propeller engines.

The ATR 42 was originally introduced in 1984, with the -600 variant beginning flight in 2010. The -600 comes in at 22.7 meters (74.4 feet) long with a wingspan of 24.6 meters (80.6 feet). Its wing area of 54.5 square meters (586.6 square feet) is designed to provide efficient lift for short-runway takeoffs and landings. With a typical seating arrangement for 44 passengers, the ATR 42-600 is an optimal choice for airlines serving regional routes with lower passenger volumes. Powered by two Pratt & Whitney Canada PW120s, the aircraft delivers a total output of 3222 kW (4,320 shp), ensuring reliable performance for its operational requirements. The ATR 42-600 has a fuel capacity of 5,730 liters (1,514 US gallons), contributing to its range of 1,326 kilometers (716 nautical miles). Its cruise speed of 556 km/h (345 mph) enables efficient travel times for regional connections.

In the competitive landscape of regional aviation, the ATR 42-600 contends with aircraft like the Bombardier Q400, Fokker 50, an Embraer EMB 120 Brasilia. Its appeal lies in its operational efficiency and suitability for short-haul routes, particularly in regions where larger jet aircraft are not viable. Airlines that have integrated the ATR 42-600 into their fleets include Silver Airways and Logan Air. These carriers utilize the aircraft to serve regional networks, capitalizing on its capacity to operate efficiently on shorter routes and provide essential connectivity.

The development of the ATR 42-600 was driven by the growing need for efficient, reliable aircraft in the regional market. Its introduction into service has been instrumental in expanding the reach of air travel to smaller markets, underscoring the importance of regional connectivity in the broader aviation industry.
