By the end of the 1990s, competition from the A330 and A340 increased significantly, so Boeing developed an option called the Boeing 767-400ER as an answer – the program was officially launched in January 1997. Soon the first customer appeared – the company “Delta”, which signed in March 1997 a contract for 21 liners. In October, Continental placed an order for 26 aircraft. The new option was supposed to take a place in the niche between the Boeing 767-300ER and Boeing 777-200, they were supposed to replace such machines as L-1011 TriStar, DC-10, and А300 in airlines, in fact, the aircraft became a direct competitor to the A330-200.
The release of aircraft began in the fall of 1999. The first aircraft was delivered to the company in the summer of 2000.
The Boeing 767-400ER had a 6.42 m elongated fuselage (one insert in front and behind the wing), capacity increased to 303 seats in the standard two-class layout or 245 seats in the three-class layout, the maximum take-off weight increased to 204,000 kg, and the flight range was up to 10460 km.
For new members of the 767 families, more powerful engine options were developed – CF6-80C2 and PW4060, which had thrust from 267 kN to 276 kN.
Initially, Boeing intended to use winglets on the Boeing 767-400ER, but then revised its approach – instead, they used elongated, 2.4 m long, and beveled wingtips of a new shape. Such a solution was technically less complicated but allowed to get the same benefits. The scope of the new wing was 51.82 m (for the Boeing 767-300ER – 47.45 m).
The Boeing 767-400ER has elongated, beveled wingtips, thanks to which it was possible to reduce the take-off run, increase climb rates and improve fuel efficiency. By the end of 2010, 37 Boeing 767-400ERs were delivered, including in Delta-21, and Continental Airlines -16.
The aircraft uses the digital avionics complex EFIS manufactured by the American company Rockwell-Collins, which has six color multifunction displays. A similar complex is used on Boeing 757 aircraft.
The instrumentation equipment of the Boeing 767-400ER cockpit included a modernized electronic flight indicator with six displays – similar to the Boeing 777 cockpit (the cockpit is also compatible with the Boeing 737NG and Boeing 747-400), the interior layout of the passenger compartment was also made according to the Boeing 777. The first Boeing 767-400ER took off in August 1999, and by 2010, 37 vehicles were already in operation.
