Widebody vs narrowbody aircraft

Widebody vs narrowbody aircraft Boeing, Airbus

  • Widebody aircraft have historically dominated the transatlantic market due to their high capacity and low costs.

  • With the rise of long-range narrowbodies, many airlines are opting to put single-aisle jets on flights across the pond.

  • Narrowbody jets are preferable for their high efficiency and profitability for low-demand city pairs.

For decades, transatlantic flying had been dominated by wide-body jets designed for high capacity long-haul travel. Historically, these twin-aisle planes were efficient because they could carry more passengers and cargo at lower operating costs, effectively pushing down ticket prices.

Jet-powered transatlantic flying, however, did not start with widebody aircraft, but rather with the de Havilland DH.106 Comet 4 operated by British Overseas Airways Corporation. The single-aisle plane flew the first regularly scheduled commercial flight across the Atlantic in 1958.

After the 747 came the wide-body trijet McDonnell Douglas DC-10 in 1971, which was engineered after airlines like American and TWA asked manufacturers to come up with a smaller, yet still high-density, long-range aircraft to meet demand.

The DC-10’s competitor was the Lockheed L-1011 TriStar, which was the third widebody to enter commercial operations in 1972 with a capacity of up to 400 passengers and a range of over 4,000 nautical miles (4,603 miles).

Commercial aircraft with three engines became standard in the industry after the FAA implemented the 60-minute rule, which restricted twin-engine jets from flying further than 60 minutes from the closest suitable diversion airport.

However, the rule was waived for trijets, opening the door for carriers, like Delta Air Lines, to operate routes that twin jets could not legally serve. Delta used the L-1011 on its first transatlantic flight from Atlanta to London Gatwick Airport in 1978.

After the success of the trijet, engineers wanted to take transatlantic flying to the next level and began engineering the famous supersonic Concorde jet. The aircraft had four engines that could propel 100 passengers across the ocean in less than four hours.

After years of flying trijets across the Atlantic, manufacturers and airlines realized the need for more efficient twin-engine jets. The trijet’s design proved to be too complex and maintenance issues arose frequently due to the middle engine being mounted on the stabilizer.

In 1972, Airbus revolutionized air travel with the world’s first twin-engine widebody aircraft, the A300B. However, twin jets were still unable to fly over oceans due to the FAA’s strict 60-minute rule, but that changed with the introduction of the Boeing 767.

The first twin-jet introduced that was capable of transatlantic flying was the Boeing 767-200ER in 1982, which pushed the development of Extended-range Twin-engine Operational Performance Standards, known as ETOPS.

The modern technology on the 767 gave the aircraft enhanced safety, reliability, and redundancy that was not seen on former commercial aircraft. The engines were highly reliable and its computerized systems enabled it to safely fly further than 60 minutes from the closest airport.

For years, ICAO, the FAA, and Boeing collected data of every engine shutdown and malfunction on the 767. The organizations wanted to determine how the aircraft would operate outside the 60-minute rule and if the change would be a safe decision.

In late-1983, Air Canada officially received an exemption to operate the Boeing 767 on routes that flew within 75 minutes of the nearest suitable airport.

Soon after, Trans World Airlines, also known as TWA, and Israeli national carrier El Al received the same permission. This opened routes across the Atlantic and to the Caribbean.

In 1984, two years after the debut of the Boeing 767, El Al operated a route from Tel Aviv, Israel to Montreal, Canada on the aircraft’s first transatlantic route, though the carrier stayed inside the 60-minute margin.

By this time, FAA director Lynn Helms, who was adamant about not changing the 60-minute rule, was no longer in charge. His successor Donald Engen was more open-minded about extending the rule.

In June 1984, Boeing received a one-time waiver to deliver the 767 from Washington Dulles to Ethiopian Airlines in Addis Adaba, Ethiopia.

Later that year, Air Canada received its first ETOPS-certified 767 that could fly the 75-minute exemption.

In 1985, Boeing engineer and test pilot Dick Taylor lobbied the FAA to extend the restrictive 75-minute rule to 120 minutes. Many airlines had already started petitioning the FAA to make the change, including TWA.

However, the FAA said that before the rule was changed, the aircraft had to prove “statistical maturity,” meaning it had to show its onboard systems and Pratt and Whitney JT9D turbofan engines were safe and reliable. Part of the test included logging 250,000 hours of consecutive passenger flight time with minimal engine shutdown.

The first revenue passenger flight to operate under the new 120-minute ETOPS rule was TWA flight 810 from Boston to Paris, using Greenland’s Kangerlussuaq Airport as the diversion airport. The 767 shortened the flight time and burned 7,000 pounds less fuel than the L-1011 on the same journey.

The 120-minute ETOPS extension was a success, but Taylor wanted to go further because it was still not enough time to make the jump from California to Hawaii. Boeing continued to collect transatlantic data and in 1989, the FAA approved the 180-minute ETOPS rule for the 767.

American Airlines operated the first ETOPS-certified flight from Dallas to Honolulu in 1989, and in 1993 the entire 767 family received 180-minute ETOPS certification.

After the certification of the 767, Airbus’ A300 family aircraft were able to fly transatlantic. American Airlines operated the twin-engine jet on several routes, including New York to London and Boston to Paris. The plane was 30% more fuel-efficient than the L-1011.

With the enhanced efficiency of twin-engine jets and the extension of ETOPS, the popularity of trijets and four-engine jets was losing momentum. By 1991, the number of passengers flying across the Atlantic on 767s exceeded those flying on jets with three or four engines, and by 2000, 50% of transatlantic journeys were made by the 767 family.

The 767 set the foundation for future twin-engines to take flight, like the Boeing 777, the Boeing 787, the Airbus A330, and the Airbus A350, which took over the routes that were traditionally dominated by trijets and four-engine aircraft.

Nevertheless, airlines have struggled to fill large passenger jets like the 500-seater A380 and point-to-point travel has become more popular among consumers who prefer direct routes versus stopping in a hub city.
