Boeing 777-300ER - "Bigger, longer and farther... "
The Boeing 777-300ER is, alongside the 777-200LR, a long-range airplane that Boeing has developed to offer airlines additional flexibility in serving nonstop routes that many passengers prefer and demand. Both aircraft were launched in February 2000, and are able to fly more passengers over a longer distance than its direct competitors, the four-engined Airbus A340-500 and A340-600. The 777-300ER was rolled out on November 14, 2002, after which flight testing began a few months later in early 2003. The first aircraft was delivered to International Lease Finance Corporation (ILFC), and their customer, Air France in April 2004. The aircraft is capable of carrying 365 passengers up to 7,930 nautical miles (14,685 km).

777 Versions

The extended range version of the 777-300 is powered by the most powerful engine available today, the GE90-115B, delivering 115,300 lbf (513 kN). Besides this, the aircraft features raked wingtips, a redesigned landing gear, additional fuel tanks (carrying 2,600 gallons of fuel) as well as a strengthened nose gear, fuselage, wings, empennage, engine struts and nacelles. The -300ER has a Maximum Take-off Weight of 775,000 lb versus 660,000 lb for the 777-300. Although the -300ER is build with fuel efficiency in mind, it is actually slightly less fuel efficient that the regular -300 because of its increased weight and more powerful engines. Both aircraft have a Basic Operating Weight (BOW) of approximately 360,000 lb as well as having similar passenger and payload capacity, but the -300ER has a higher MTOW and therefore can carry about 110,000 lb more fuel. The additional fuel load enables the 777-300ER to fly approximately 34% farther than the -300 with the same payload.

Part of the 777-300ER ETOPS certification process was test flying the aircraft with only one working engine for as long as six hours and 29 minutes (equivalent to 389 minutes) over the Pacific Ocean. To put this into perspective; achieving 180 minutes of succesful and reliable operation on one operating engine is sufficient to obtain ETOPS certification.

Boeing 777-300ER Design
As already pointed out earlier, the Boeing 777-300ER features some rather unique improvements in order to improve fuel efficiency and overal performance. The new highly tapered raked wingtip extentions, also found on the 777-200LR, have been fitted to reduce take-off field length, climb performance and fuel efficiency. Through the use of raked wingtips, the 777-300ER is expected to achieve a 2 percent fuel efficiency improvement, which could save as much as $140,000 U.S. dollars on fuel costs per year per airplane. This can be translated into savings of 1.3 million pounds of fuel per year per airplane, and 3.9 million less pounds of global warming carbon dioxide (CO2) being emitted into the environment.
 
Landing Gear

Furthermore, in order to make up for the additional weight, the 777-300ER is fitted with the largest commercial landing gear built today. The main gear, when fully assembled with wheels, brakes and tires, stands over 16.5 feet high and weighs approximately 12,000 pounds. The gear is produced by Goodrich Corporation who is part of the Boeing 777-300ER's Integrated Product Team. The unique gear allows the airplane to rotate early by shifting the center of rotation from the main axle to the aft axle of the three-axle landing gear truck. As the airplane rotates, the nose is allowed to rise higher earlier. Although this feature is independent of the Tail-Strike Protection system, it gives customers the ability to take-off on shorter runways or put more payload on the airplane for the same length of runway.

Although the main landing gear of the 777 is in a standard two-post arrangement, it features six-wheel trucks, instead of the conventional four-wheel units. It provides the aircraft with a total of 12 wheels for better weight distribution on runways and taxiway areas, while avoiding the need for a supplemental two-wheel gear under the center of the fuselage, like the MD-11 has. Nice detail is that the 777's landing gear is the largest ever incorporated into a commercial airplane

 
Flight Deck
The flight deck of the Boeing 777 is somewhat similar to that of the Boeing 747-400. Flight, navigation and engine information is presented on six large display screens, incorporating advanced LCD (Liquid Cristal Display) technology. This new technology weighs less and requires less power while generating less heat, which contributes to greater reliability and longer service life compared to the conventional CRT (Cathode Ray Tube) screens. Control Display Units (CDUs), installed in the center aisle stand, provide data entry and display capabilities for flight management functions. Compared to older generation FMC systems, the Boeing 777 incorporates CDUs with color displays which allow pilots to assimilate the information more quickly.
 
Flight Controls
As already pointed out earlier, the Boeing 777 is equipped with fly-by-wire technology. This means that the flight crew transmits control and maneuvering commands through electrical wires, augmented by computers, directly to hydraulic actuators for the elevators, ailerons, rudder and other control surfaces. Fly-by-wire technology already proved to be highly efficient and reliable on many fighter aircraft as well as on Airbus aircraft. The lack of mechanical linkages saves weight and simplifies factory assembly while requiring less costly maintenance hours.

Avionics
A key part of the systems incorporated in the Boeing 777 design, is a two-way digital data bus, known as ARINC 629. The system allows airplane systems, including associated computers, to communicate with one another through a common wire path instead of through one-way wire connections. This system also simplifies assembly and saves weight, while increasing reliability through a reduction in the amount of wires and connectors. There are a total of 11 of these ARINC 629 pathways in the Boeing 777. The Boeing 777 was the first aircraft ever to be equipped with the Enhanced Ground Proximity Warning System (EGPWS) as standard. The EGPWS equipment displays potentially threatening terrain and gives an audible alert up to a minute in advance of possible terrain conflict.

Boeing 777-200
Boeing 777-200 Information
The Boeing 777-200 is the base-line model of the 777. The first aircraft was delivered to United Airlines in May 1995. The aircraft was build by Boeing's non-destructive testing campaign in 94' - 95', and provided valuable knowledge for the later 777 programs.
 
Boeing 777-200ER
Boeing 777-200ER Information
The Boeing 777-200ER was taken into service in 1997, roughly two years after the first 777 was delivered to United Airlines. It featured increased fuel capacity as well as more powerful engines. ER stands for Extended Range as the -200ER is able to fly significantly farther than the -200. The first airframe was delivered to British Airways.
 
Boeing 777-200LR
Boeing 777-200LR Information
The Boeing 777-200LR (Longer Range) entered service in 2006 and became the world's longest range commercial airliner. The -200LR, also known as Worldliner, is able to connect almost any two citypairs in the world. It is capable of flying 9.450 nautical miles within a time span of 18 hours. The first airframe was delivered to launch customer Pakistan International Airlines (PIA) on February 26, 2006.
 
Boeing 777-300
Boeing 777-300 Information
The Boeing 777-300 was originally designed as a replacement for the 747-100 and -200 aircraft. It features a 33 feet fuselage stretch over the baseline 777-200 and allows for up to 550 passengers in a single class cabin configuration. The first aircraft was put into service by Cathay Pacific in June, 1998.
 
Boeing 777-300ER
Boeing 777-300ER Information
The Boeing 777-300ER (Extended Range) is the longer range version of the Boeing 777-300. It contains many modifications, including the most powerful engines ever produced, the GE90-115B. The aircraft is also equipped with raked wingtips, additional fuel tanks, strengthened main landing gear and fuselage and a higher Maximum Take-off Weight (MTOW). The first aircraft was delivered to Air France on April 29, 2004
