Bombardier CRJ-700 vs. McDonnell Douglas MD-11

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.

The McDonnell Douglas MD-11 is a wide-body, tri-jet airliner, recognized for its extended range and enhanced capabilities in long-haul commercial aviation. As a successor to the iconic DC-10, the MD-11 incorporated advanced technology and design improvements, making it a significant model in the evolution of wide-body aircraft. The MD-11 took its maiden flight in 1990, and was produced until the turn of the 21st century. There are no MD-11s servicing passenger flights today, but some MD-11 are still being used for freight operations with FedEx, UPS, and Western Global Airlines.

With a length of 61.6 meters (202.1 feet), the MD-11 is notably longer than the DC-10, which provided increased passenger and cargo capacity. This extension in length was complemented by a wingspan of 52.0 meters (170.5 feet), which included winglets for improved aerodynamic efficiency. The MD-11's was equipped with GE CF6-80C2s or PW4000 turbofan engines, which delivered a total maximum thrust of 822.0 kN (123,000 lbf). With a substantial fuel capacity of 146,173 liters (38,615 US gallons), the MD-11 boasts a range of approximately 12,455 kilometers (6,725 nautical miles), enabling it to operate on intercontinental routes with ease.

The MD-11 comfortably accommodated 298 passengers, and could be designed to fit over 340 in a higher density configuration. The most common configurations for the twin aisle jet included 9 seats to a row (3-3-3 or 3-4-2).

In the competitive landscape of long-haul airliners, the McDonnell Douglas MD-11 was positioned as an alternative to models like the Boeing 747 and the Lockheed L-1011 TriStar. By 2004, most carriers that utilized the MD-11 for long-haul passenger routes had replaced it with the Airbus A330, A340, and Boeing 777. When Boeing acquired McDonnell Douglas in 1997, it ultimately created internal competition for the MD-11 with the 767 and 777. A lack of interest from the market also lead to Boeing cutting production for the commercial variant short, while the freight version was continued for slightly longer.

KLM, Swissair, and Delta Air Lines were among the airlines who utilized the aircraft's range and capacity to expand their international route offerings. The MD-11's operational role was characterized by its ability to efficiently serve long-haul routes, offering a blend of passenger comfort and operational economics. Some airlines like China Eastern Airlines and Korean Air had converted their MD-11 aircraft into freighters rather than selling or retiring them.

The MD-11's production and service history reflect its role as a pivotal model in the wide-body aircraft segment. Its design and technological advancements, including the use of winglets and a glass cockpit, marked important steps in the advancement of commercial aircraft design. Although its production was eventually surpassed by more modern aircraft, the MD-11 remains a notable aircraft in the history of aviation, particularly for its contributions to long-haul air travel.
