The Boeing 767-400ER has some characteristics as: is sized between the Boeing 767-300ER and the Boeing 777-200, has aerodynamic improvements, including additional wing span; increased takeoff weight capability; has a lengthened fuselage; and also an all-new main landing gear.
This aircraft is stretched version of the 767-300ER addresses the medium-size (240- to 300-seat) intercontinental market, accommodating growth on routes that don’t require the capacity of a 777.
The 767-400ER also replaces older aircrafts serving transcontinental routes. The first 767-400ERs were delivered to Delta Air Lines and Continental Airlines in August 2000. The first 767-400ER went into service on Sept. 14, 2000.
This aircraft brings major improvements in operating economics over competing aircrafts in the 240- to 300-seat market:
- Additional range
- Increased payload capability
- Commonality with other Boeing jetliners
- Superior passenger comfort
The Boeing 767-400ER: A Versatile Airplane For a Dynamic Market
This model features a fuselage that is 11 feet (3.4 m) longer than the 767-300ER model, and carries approximately 12 percent more passengers. The additional seats reduce seat-mile costs relative to the 767-300ER, which already offers airlines the lowest operating costs in its class.
First widebody airplane to offer a choice of three passenger sizes — the 767-200ER, 767-300ER and 767-400ER.
While debate continues over the best way to reduce noise, one fact is beyond dispute: The 767 family is quiet, and the newest family members, such as the 767-400ER, are the quietest of all.
Boeing 767-400ER Exterior
It is designed to be the most competent aircraft in its size class, making it an ideal substitute for aging L-1011, DC-10-30 and A300 airplanes.
In growing markets, it can fly more passengers on routes served by existing 767s, A300-600s and A310s. Efficient design gives the higher-capacity 767-400ER excellent range capacity (almost 5,635 nautical miles or 10,415 km) to fly about 99 percent of the routes currently being served by airplanes in this size category.
21 feet (6.43 m) longer than the 767-300ER
The three passenger models differ primarily in body length, with the Boeing 767-300ER approximately 21 feet (6.43 m) longer than the 767-200ER, and the 767-400ER approximately 21 feet (6.43 m) longer than the 767-300ER. The twin-engine 767 — sized between the single-aisle 757 and the larger, twin-aisle 777 — has built a reputation among airlines for its profitability and comfort.
The 767 seats from as few as 181 passengers in a three-class seating arrangement on the 767-200ER to as many as 375 passengers in a high-density charter configuration on a 767-400ER.
The extended-range airplanes typically have three-class seating of 181 to 245 passengers, using five-abreast, 747-size first-class seats; six-abreast business class seats; and seven-abreast economy class seats.
Lower-deck volume available for luggage and cargo ranges from 2,925 cubic feet (82.9 cu m) for the 767-200ER to 4,670 cubic feet (132.3 cu m) for the 767-400ER.
Boeing’s 767-400ER was designed to replace early A300, A310 and 767 twins used on transcontinental services and DC-10-30s and L-1011 trijets used for intercontinental work.
It competes with the A330-200.
Design work on the then 767-400ERX began in late 1996 when Boeing signed a technical assistance agreement covering the program with the then independent Douglas Aircraft Company division of McDonnell Douglas.
Maximum Fuel Capacity - 90,770 L
Because of the increased fuselage length the -400 features all new, 46cm (18in) taller landing gear to restore rotation angles for acceptable takeoff and landing speeds and distances which would otherwise have been adversely affected by the fuselage stretch. The wheels, tyres and brakes are common with the 777.
Compared to the 767-300, the 767-400ER’s wing characteristics 2.34m (7ft 8in) long raked wingtips which enhance aerodynamic efficiency. Winglets were originally considered but the wingtip extensions proved more efficient. The wing is also made from increased gauge aluminium with thicker spars.
Wing span 51.92m (170ft 4in), length 61.37m (201ft 4in), height 16.87m (55ft 4in)
Boeing 767-400ER Interior
All passenger models of the 767 family give you a new, even more passenger-pleasing cabin interior. Some essential characteristics are:
- uses state-of-the-art lighting and design concepts to amplify the feeling of spaciousness on an airplane already prized for long-range comfort.
- offers airlines amplified flexibility in positioning and maintaining lavatories.
- also features an improved in-flight entertainment interface.
- includes new, deeper stowage bins, that make easier finding space in the compartments.
The 767 has earned high passenger ratings in every class of service. In economy class seating, the 767 offers a seat-width that is only surpassed by the Boeing 777.
An independent investigation has shown the seven-abreast seating concept in economy is popular because it places 87 percent of the seats next to a window or aisle.
The 767 has the highest percentage of window seats and aisle seats of any jetliner.
Flightcrew of two.
Typical three class arrangement for 245 passengers, comprising 20 first class at 152cm (60in) pitch, 50 business at 97cm (38in) and 175 economy at 81cm (32in).
Boeing 767-400ER Avionics
Inside, the 767-400ER features a 777 style advanced flight deck with six color multifunction displays, which can present information in the same format as earlier 767s, permitting a common type certificate, or as for the 777 and Next Generation 737s. The all new passenger interior is similar to that in the 777.
The LFDS uses six 8- by 8-in liquid crystal displays (LCD) to display information about primary flight and navigation, engine indication and crew alerting system, synoptics, interface controls, and maintenance data.
The 767-400ER flight deck instrument panel has 82 percent fewer parts than other 767s.
The 767-300ER and 767-400ER hold 23,980 gallons (90,770 l) of fuel - enough to fill 1,200 minivans. It takes only 28 minutes to fill the airplane.
Boeing 767-400ER Engine
Other features include common engines with the 767-300, a new APU, new tailskid and increased weights.
The air flowing through a 767-400ER engine at takeoff power could inflate the Goodyear Blimp in seven seconds.
It takes about 60 gallons (227 l) of fuel per passenger to get from New York to London on board a 767-400ER. The same volume of gasoline would propel an economy car about half of that distance.
- Two 281.6kN (63,300lb) Pratt & Whitney PW4062 turbofans,
- or two 276.2kN (62,100lb) General Electric CF6-80C2B7F1s
- or 282.5kN (63,500lb) CF6-80C2B8Fs.
Design cruising speed 0.80 Mach.
Design range at max takeoff weight with max passengers 10,343km (5580nm) with PW4062s, 10,418km (5625nm) with CF6-80C2B8Fs.
Operating empty with PW4062s 103,145kg (227,400lb), 103,100kg (227,300lb) with CF6-80C2B8Fs, max takeoff 204,120kg (450,000lb).
Boeing 767-400ER Safety
If we make a comparison with the Airbus A330-200, the Boeing 767-400ER presents a superior economic performance — having at least 5 percent lower operating costs. Another advantage is that 767-400ER weighs 40,000 pounds less than the A330-200.
The 767-400ER can fly all U.S. domestic routes as well as North Atlantic routes such as Newark-Moscow, Los Angeles-London or Chicago-Warsaw. Other possible routes include New York-Santiago, Seattle-Osaka, Chile and Atlanta-Honolulu.
In April 28, 1997, when Atlanta-based Delta Air Lines announced its intent to order 21 airplanes - the Boeing 767-400ER was launched.
Also Continental Airlines ordered 26 airplanes on Oct. 10, 1997.
The first aircraft rolled out of the Boeing factory Aug. 26, 1999 and made its inaugural flight Oct. 9, 1999.
First aircraft delivered August 2000
The first aircraft were delivered to Continental Airlines and Delta Air Lines in August 2000 and also this aircraft went into service on Sept. 14, the same year.
The Boeing 767 family is a complete family of clean, quiet, fuel-efficient airplanes that provide maximum market versatility in the 200- to 300-seat market. The Boeing 767 family includes three passenger models — the 767-200ER, 767-300ER and 767-400ER — and a medium-widebody freighter, which is based on the 767-300ER fuselage.
Orders for the 767-400 as of December 2001 stood at 40 with 24 aircraft delivered. In current production.
