Boeing 737-500 vs. Bombardier CRJ-700

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 Bombardier CRJ-700 is a narrow-body regional aircraft, designed for short to medium-haul routes. Introduced in 1999 as a member of the Canadair Regional Jet series, the CRJ-700 is a stretched derivative of the CRJ200. Regional carriers use CRJs, like the -700, to serve smaller cities and transport passengers to hub airports for connecting flights.

The CRJ-700 is approximately 32 meters (106.0 feet) long, and 23.3 meters (76.4 feet) from wing tip to wing tip. This aircraft is tailored for operations in smaller airport environments with limited runway lengths. The size and design of the CRJ-700 facilitate efficient airport operations and quick turnarounds, essential for the high-frequency schedules typical of regional airlines. Powered by General Electric engines capable of delivering a maximum thrust of 122.6 kN (27,600 lbf), the CRJ-700 is equipped for a range of approximately 2,593 kilometers (1,400 nautical miles). This range allows airlines to deploy the aircraft on a wide array of routes, from short hops to longer regional journeys, without sacrificing efficiency or performance. CRJ-700 flights can typically range anywhere from 30 minutes to a couple hours in duration.

The cabin of the CRJ-700 is designed to seat around 66-78 passengers in a standard single-class configuration. Features such as improved cabin lighting, ergonomic seating, and overhead storage contribute to an enhanced passenger experience. Additionally, the cabin's design allows for quick and efficient boarding and deplaning, a key consideration in regional air travel.

In the competitive landscape of regional aircraft, the Bombardier CRJ-700 holds its ground against counterparts like the Embraer E175. The CRJ-700's introduction served to address a growing market demand for regional jets that could offer better performance, more seats, and improved passenger comfort compared to earlier models. US-based airlines including American Eagle, Delta Connection, and United Express have utilized the CRJ-700 extensively. Its operational strengths make it well-suited for building and maintaining effective regional networks, providing vital connectivity between smaller cities and major airports. The aircraft's role extends beyond just transportation; it facilitates economic growth and accessibility to remote areas, proving to be a valuable asset in the regional aviation sector. At launch, the -700 had an estimated sale price of $35 million. Production for the entire CRJ family was discontinued after 2021.
