Introduction to the Boeing 767
The Boeing 767 is a low wing, twin-engined, long-range jet airliner which was Boeings’ first wide-body twin-jet. This was Boeing’s first new model after the introduction of the Boeing 747 and was designed to take over the market that was serviced by the ageing Boeing 707 and Douglas DC8. Through its lifetime the 767 also filled the space left over by the phasing out of the Lockheed L1011 Tristar as well as the McDonnell Douglas DC-10.
The Boeing 767 was developed in parallel with the Boeing 757. Where the Boeing 767 was a widebody aircraft, yet not as wide as the Boeing 747, with a standard economy layout of 7 abreast as opposed to the 747’s 10 abreast. The 757 was a narrow body, much like the Boeing 707 with 6 abreast. The 767 and 757 shared much of the same design and technology which was a huge saving for Boeing.
One of the new technologies was the introduction of the glass cockpit.
One of the new technologies was the introduction of the glass cockpit. For the first time, computer screens started to replace or at least duplicate many of the flight, navigation and system status dials. There were obvious advantages of weight saving as well as fail-safe systems. However, for the first time, a large airliner was produced that only required a crew of two. Even the first Airbus A300, the first model produced by Airbus Industrie started life with a 3 crew cockpit. Some airlines, like Ansett Australia, still opted for a 3 crew cockpit, due to union pressure.
The Boeing 767 was produced in three difference fuselage lengths as well as short and long-range versions of these which can be seen in the specs table below.
The first aircraft produced was the 767 200 variant which went into service in 1982. This was still the early days for large twin-engined jet airliners and there were ETOPS (Extended-range Twin-engine Operational Performance Standards) restrictions in place which prevented these aircraft from being flown initially more than 90 minutes from a serviceable airfield. This was gradually stepped up through the 1980s as engines became more reliable, with 767s equipped with General Electric CF-6 engines being granted ETOPS180 approval in 1989.
This meant that the 767 could now fly up to 180 minutes from the nearest airfield
This meant that the 767 could now fly up to 180 minutes from the nearest airfield and enabled trans-North Atlantic flights. By 1993 all engine options for the 767 were granted ETOPS180.
Initially, the 767 was used on domestic and transcontinental flights (USA). With the extended ETOPS approval, the door was now open to use this mid-range aircraft on routes like the North Atlantic, a route previously reserved for aircraft with more than 2 engines. This was great for the airlines who could now schedule aircraft with varying capacity over this heavy traffic route.
The Boeing 767 has been in production now for 33 years and was planned to be phased out and replaced by the very popular Boeing 787 Dreamliner. The 787 suffered many delays and some airlines chose to take the Boeing 767 300ER in its place as they could no longer wait. Many 767s that were for due retirement in favour of the 787 were kept in service and airlines had to implement extensive D check maintenance to ensure these aircraft remained flight worthy and free of corrosion.
Boeing also offered a retrofit of winglets in 2008.
Boeing also offered a retrofit of winglets in 2008. These 3.35-metre wing extensions enabled a 6.5 per cent fuel saving and several airlines took this option up to extend the life of their 767 fleets. Boeing, seeing this renewed interest in the 767, proposed to the market an updated version of the 767 200 and 767 300F. The reception was very lukewarm and the idea was soon shelved.
In February 2011 a 767 300ER that was delivered to All Nippon Airways of Japan was the 1,000th 767 to be delivered. Boeing held the record of having produced the only too wide-bodied jets to have reached this milestone. It also signified a change as 767 production was moved to a smaller part of the Everett factory to make room for the Boeing 787 Dreamliner assembly line. Orders for the 767 passenger version started to wane, however, the 767 cargo version was still in demand as is the air force tanker version.
Let’s have a look at the timeline for the Boeing 767.
|1972||Development study begins on the 7X7 which would replace the Boeing 707|
|1976||A twinjet layout was decided upon, much like the Airbus’ A300.|
|February 1978||The 767 designator was decided upon and three variants planned. The 767-100 (190 seats), 767-200 (210 seats) and the 767-MR/LR (Medium Range / Long Range). The 767-MR/LR was proposed as a tri-jet to get around ETOPS restrictions. This was later redesignated the 777 with the tri-jet configuration dropped. The 767-100 was dropped as its capacity was too close to the 757.|
