The 777-300ER extends the 777 family’s span of capabilities, bringing twin-engine efficiency and reliability to the long-range market. The airplane carries 365 passengers up to 7,930 nautical miles (14,685 km).
Also the longer-range 777-300ER entered service in 2006 and a freighter version, the 777F, debuted in 2008.
Both longer-range versions (300ER and 200LR) and the freighter have General Electric GE90 engines, as well as extended and raked wingtips.
The other models are provided with the GE90, Pratt & Whitney PW4000, or Rolls-Royce Trent 800 engines.

On February 29, 2000, Boeing inaugurated its next-generation twinjet program, firstly called 777-X, and began issuing offers to airlines. The expansion of the long-range versions was slowed by the airline industry downturn, which lasted through the early 2000s.
The first model to become visible from the program, the 777-300ER, was launched with an order for ten aircraft from Air France, along with additional commitments. On February 24, 2003, the Boeing 777-300ER made its first flight, and the FAA and EASA (European Aviation Safety Agency, successor to the JAA) certified the model on March 16, 2004. Also the first delivery to Air France was made on April 29, 2004.

Boeing 777-300ER Exterior
The 777-300ER ("ER" for Extended Range) being the B-market variant of the -300 has some important features like: extended wingtips, a new main landing gear, reinforced nose gear, and extra fuel tanks. This aircraft also has a strengthened fuselage, wings, empennage, and engine attachments.
The Boeing 777-300ER aircraft, which merged the -300’s added capacity with the -200ER’s range, became the top-selling 777 model, obtaining orders as airlines replaced comparable four-engine models with twinjets because of their lower operating costs.
The advantages were also put into practice during development of the 777-200LR and the 777 Freighter.
The Boeing 777-200LR Worldliner and also 777-300ER have seat-mile costs that are 18 to 20 percent lower than the A340-500 and A340-600 models.
Approximately 35 percent of the 777-300ER and 777-200LR Worldliner design has been improved from earlier 777 models, although passengers won’t notice it.
Each wing is being extended by 6.5 feet by adding raked wingtips to develop overall aerodynamic efficiency. The raked wingtips help reduce takeoff field length, increase climb performance and reduce fuel burn.
The body, wing, nose gear and empennage of the aircrafts were strengthened and new main landing gear, wheels, tires and brakes were mounted.
The struts and nacelles were adapted to accommodate the significantly higher-thrust engines.
Tail-strike protection is standard on both models. This software feature helps prevent inadvertent scraping of the tail on the runway at takeoff or landing by commanding elevator movement if the aircraft’s attitude exceeds pre-set limits.

Boeing 777-300ER Interior
Carries 365 passengers up to 7,930 nautical miles
The 777-300ER extends the 777 family’s span of capabilities, bringing twin-engine efficiency and reliability to the long-range market.
The aircraft transports 365 passengers up to 7,930 nautical miles (14,685 km).
The 777-300ER Worldliner offers overhead crew and attendant rest areas in the fuselage crown
above the passenger cabin. Most aircrafts have crew rest areas either in the passenger cabin or in the cargo compartment.
By moving crew and attendant quarters off the main deck, 777 operators can free as many as four-to-seven revenue passenger seats.
Alternatively, using overhead crew rest areas frees up room for additional capacity in the cargo compartment, up to six LD-3 containers.
The 777-300ER will give you the widest seats in all classes:
- First-class passengers on all 777 models have 21-inch (53 cm) wide seats, which permit passengers to enjoy the same level of comfort as on the 747;
- Business-class seats are 20 inches (50 cm) wide — the same width as the A340’s first-class seats;
- Economy class has standard 18.5-inch (47 cm) wide — the widest in the industry — compared to 17.2-inch (44 cm) wide seats on the A340;
Boeing incorporated several performance developments for the 777-300ER, extending its range and payload capabilities.
Excellent performance during flight testing, combined with engine efficiency developments and design transformations that reduce drag and aircraft weight, contributed to the increased capability. The benefits were also applied during development of the 777-200LR and the 777 Freighter.
Like other members of the 777 family, both the 777-200LR Worldliner and the 777-300ER 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.
By utilizing the overhead space, the 777-200ER (Extended Range) and 777-200LR (Longer-Range) can save up to four passenger seats and four cargo containers, and the 777-300ER saves up to seven seats and six cargo containers. This frees up the seat and cargo space and results in additional revenue potential.
The six-or-seven- bunk attendant rest station, available on the 777-200ER, 777-200LR and 777-300ER, can be accessed from stairs located at the mid-section of the airplane.
The 777-300ER has options for a six-, eight- or 10-bunk arrangement, with the entrance located at the rear of the airplane. The 777-200LR has options for a six- or eight-bunk arrangement.
Airline customers can select any of the overhead features on their new 777-200ERs, 777-300ERs and 777-200LRs.
In 2009, the 777-300ER was awarded "Best of 2009," open category, as voted by the readers of Brazilian magazine Aero.
Boeing 777-300ER Avionics
In response to airline inclination, the layout of the 777 flight deck is in a horizontal format similar to that of the 747-400.
On six large display screens are presented: principal flight, engine information and navigation.
Although these displays resemble conventional cathode ray tube (CRT) screens, they contain superior liquid-crystal display technology.
The depth of the new flat panel displays is about half that of CRTs. In addition to saving space, the new displays weigh less and necessitate less power. They also generate less heat, which contributes to greater reliability and a longer service life. As another advantage, the displays do not require the heavy, complex air conditioning apparatus needed to cool equipment on previous flight decks. Pilots are grateful because that flat panel displays remain clearly visible in all conditions, even direct sunlight.
Boeing 777-300ER Engine
The Boeing 777-300ER has seat-mile costs that are 18 to 20 percent lower than the A340-500 and A340-600 models. Fuel burn is considerably lower — 21 to 22 percent lower per seat for the longer-range 777s — when compared to the A340-500 and A340-600. The 777 also uses advanced technology that lowers maintenance costs and makes maintenance more efficient.
GE Aircraft Engines [NYSE: GE] manufactures the engines for the 777-200LR and 777-300ER aircrafts. The new engines is considered the world’s most powerful commercial jet engines and currently hold a Guinness World Record for thrust.
Boeing 777-300ER was launched in February 2002 by Boeing and GE Aircraft Engines at the demand of customers who asked for an aircraft with extra flexibility to serve the non-stop routes that passengers order.
777-300ER Extended range 777-300 model with more powerful engines and additional fuel carried in a wing of increased span as well as two auxiliary tanks in the cargo hold, originally known as the 777-300X .
The Boeing 777-300ER’s fuselage is exactly the same of -300 excepting that it has a wider wingspan due to wingtips. Using a two classes and three classes configurations it can accommodate between 339 and 370 passengers respectively.
In July 2004, Dubai-based carrier Emirates agreed to purchase 13 Boeing 777-300ERs with four aircraft on firm orders will be delivered during 2006 and the rest as option to be delivered from 2006 though 2012.
