Competition (Konkurrenz)
Airbus A340

Remarks (Bemerkungen)
The 777-300 is the largest twin-engined airliner ever and also the longest one, beating even the 747. In fact, it offers roughly the same capacity and range as the early generation 747-100/200s, which it tries replace over time. According to Boeing, the new twin is 33 per cent more effective, with maintenance costs reduced by 40 per cent. Modifications over the 777-200 include:

fuselage stretch, adding ten frames (5,3 m) to section 43 forward of the wing and nine frames (4,8 m) to section 46 behind.
tail skid
ground manoeuvre cameras in the horizontal stabilisers and under the front fuselage
strengthened fuselage sections (particularly at wing/fuselage join), plus stronger keel beams to the tail
strengthened nose and main gear
strengthened inboard wing, with thicker skins

History (Geschichte)
The stretch of the 777-200 basic variant was first revealed at the Paris Air Show in June 1995 and launched by the Boeing board on June 26. The final configuration was frozen in October. Detailed fabrication began in February 1996, and major assembly started in April 1997. The roll-out ceremony took place at the Everett plant on 8. September. First flight followed on 16 October 1997. It lasted four hours and six minutes. The aircraft was fitted with Trent engines, the first time a Boeing airliner has made its maiden sortie with a non-US engine.
A total of five aircraft were involved in the flight tests, which totalled about 1500 h. Test aircraft are:

WB501 (Trent engines): 500 h of aerodynamic testing, flutter clearance, take-off performance, stability evaluation
WB502 (Trent engines): performance testing, validation of nav-system and other avionics
WB531 (PW4090 engines): 200 h of fuel consumption and systems tests
WB551 (PW4098 engines): 400 h on engine tests
WB503: 80 h in two months of cabin interior and in-flight entertainment systems tests

Simultaneous FAA and JAA certification of the Trent-powered variant was achieved on May 5, 1998. The FAA ok included approval for 180-minute ETOPS (extended-range, twin-engine operations). First delivery - to Cathay Pacific - followed on 22 May 1998.
