1998 Boeing 777-300

Posted on by 0

The Boeing 777-300 is a stretched version of the 777, powered by the most powerful turbofan engines, seating 328 to 394 passengers in a typical three class seating arrangement or 550 passengers in a single economy class arrangement.

This aircraft is the latest derivative of the 777 family and the first airplane was given to Cathay Pacific in May 1998. 60 aircraft were sent and production is complete.

The stretched 777-300 is designed as a substitute for early generation 747s (747-100s and 200s). Compared to the older 747s the stretched 777 has similar passenger capacity and range, but burns one third less fuel and present 40% lower maintenance costs.

Compared with the baseline 777-200 the 300 features a 10.13m (33ft 3in) stretch, comprising plugs fore and aft of the wings.
Boeing publicly announced it was developing the 777-300 at the Paris Air show in mid June 1995 where it exposed it had secured 31 firm orders from All Nippon, Cathay Pacific, Korean Airlines and Thai Airways. Later that month Boeing’s board certified production of the new airplane.
The 777-300 rolled out on September 8 1997, followed by first flight on October 16 that year. The type made history on May 4 1998 when it was awarded type certification simultaneously from the US FAA and European JAA and was granted 180min ETOPS approval. Service entry with Cathay Pacific was later in that month.

The Boeing 777-300 - an improved model

Like the 777-200, a 777-300 model has been developed.
There are some modifications made to the 777-300ER like: some more powerful General Electric GE90-115B engines (currently the world’s most powerful jet engine), raked wingtips, strengthened body, wings, empennage, nose gear, engine struts and nacelles, new main landing gear, and provision for extra fuel tanks.
The range, transporting 365 passengers, is increased up to 13,427km (7,250nm).

Roll-out of the first 777-300ER was made on November 14 2002, after the first flight on February 24 2003. First delivery, to Air France, is scheduled for March 2004.

Compared with the baseline 777-200 the 777-300 features a 10,13 m stretch, comprising plugs fore and aft of the wings.
The 777-300ER is the first of two new Longer-Range 777 models. The 777-300ER and the 777-200LR (Longer Range) were launched in February 2000 at the request of airline customers seeking airplanes with additional flexibility to serve the non-stop routes that passengers demand.
During the 777-300ER’s 1,500-hour flight test program, the airplane exceeded its original design performance targets. As a result, the new jetliner provides increased payload and range capability over those promised to customers at the time of the airplane sale.

GE90-115B turbofans -the most powerful commercial jet engines

General Electric Aircraft Engines manufactures the engines for both Longer-Range 777 models. The GE90-115B turbofan is the world’s largest and most powerful commercial jet engine, producing 115,000 pounds of thrust, currently a Guinness World Record.

On Friday, December 3, 2004 was the rollout of the 500th Boeing 777 commercial airplane. The Boeing 777 the fastest-selling twin-aisle airplane ever, will reach 500 airplanes delivered faster than any other twin-aisle airplane in commercial history. The 500th 777 is scheduled for delivery to International Lease Finance Corp. and operator Air France later this month. Thirty-eight customers have ordered 647 Boeing 777.

The stretched 777-300 was designed as an A-market replacement for 747-100s and 747-200s.[65] Compared to the older 747s, the stretched variant has comparable passenger capacity and range, and is designed to burn one-third less fuel and have 40 percent lower maintenance costs.
Because of the aircraft’s length, the -300 is outfitted with a tailskid and ground maneuvering cameras to aid pilots during taxi. The maximum range is 6,015 nautical miles (11,140 km), allowing the -300 to operate trunk routes previously flown by older 747s.

delivered to Cathay Pacific on May 21, 1998

The first -300 was delivered to Cathay Pacific on May 21, 1998.
Eight different -300 customers have taken delivery of 60 aircraft, and all were in airline service as of July 2009. However, following the introduction of the longer-range -300ER in 2004, all operators have selected the ER version of the -300 variant. The -300 has no direct Airbus rival, but the A340-600 is offered in competition.

The longer fuselage permits seating for up to 550 passengers in a single class high density arrangement.
To cope with the stretch and the up to 13 tones (28,600lb) increased max takeoff weight the 300 features a strengthened undercarriage, airframe and inboard wing.
Other modifications compared with the 777-200 consist of: a tailskid and ground maneuvering cameras mounted on the horizontal tail and underneath the forward fuselage. Otherwise changes have been kept to a minimum to maximize commonality.

Comfort

Like other members of the 777 family, both the 777-200LR Worldliner and the 777-300 offer the widest seats in all classes when compared to the A340. First-class passengers on all 777 models have 21-inch-wide (53 cm) seats, which allow passengers to enjoy the same level of comfort as on the 747.

Boeing 777-300 Engine

Boeing 777-300

Boeing’s 777-300 is powered by the world’s most powerful turbofan engines.
The GE90-115B turbofan is the world’s largest and most powerful commercial jet engine, this engine produces 115,000 pounds of thrust, at present a Guinness World Record.
Boeing has revised the strut limitation of the 777-300, permitting powerplant manufacturers to give a higher level of available engine thrust, having improved payload performance from hot/ high and restricted runways.

The Boeing 777-300 has:

  • two Pratt & Whitney - PW 4098 98,000 lbf (developing 430 kN)
  • or two Rolls-Royce Trent 892s - RR 892 : 95,000 lbf (developing 400 kN)
  • or two General electric GE90- 92Bs - GE90-92B 94,000/92,000 lbf (developing 410 kN)

Also the Boeing 777 is larger than all other twinjet (two engines) or trijet (three engines) airplane. This aircraft is capable of seating more passengers than other models.

Typical cruise speed0.84 Mach (560 mph, 905 km/h, 490 knots) at 35,000 ft (11,000 m) cruise altitude
Maximum cruise speed0.89 Mach (590 mph, 950 km/h, 512 knots) at 35,000 ft (11,000 m) cruise altitude
Maximum range4,885 nmi (9,045 km)

Boeing 777-300 Avionics

Boeing 777-300

Boeing’s advanced widebody 777 twin incorporates more advanced technologies than any other previous Boeing airliner, and has been progressively developed into progressively more longer range developments.
The Boeing 777 is the first aircraft to be fully digitally designed using 3D computer graphics eliminating the need for costly full-scale mock-ups.

An advanced technology glass flightdeck

The result is an aircraft larger than all other twin-engine and tri-engine aircraft and smaller than Boeing 747 aircraft while aimed at the medium and long range markets and bringing the low-costs benefits owned by twin-engine aircraft.


Notable 777 design features include a unique fuselage cross section, Boeing’s first application of fly-by-wire, an advanced technology glass flightdeck with five liquid crystal displays, comparatively large scale use of composites (10% by weight), and advanced and extremely powerful engines.

Pricing and Cost

In 2008 the price for the Boeing 767-300 was between $ 257.0 - 286.5 million.
