| Boeing 777-200ER |
The Boeing 777 was the first aircraft ever to be fully digitally designed using three-dimensional computer graphics. Using this method eliminated the need for costly mock-ups and test equipment. The Boeing 777 program was launched in October 1990 with an order from United Airlines. Almost 5 years later, United Airlines flew its first revenue service. Work on the Boeing 777-200(ER) commenced 6 years later in 1996 with the roll-out following later that year.
The Boeing 777-200ER, originally known as the Boeing 777-200IGW (Increased Gross Weight), was designed especially for the longer-range B market (5.800 to 7.700 nautical miles) and compared to the basic -200 model it features increased fuel capacity together with an increase in Maximum Take-off Weight to make up for range capability between 6.100 and 7.700 nautical miles. In February 1997, the first Boeing 777-200ER was delivered to launch customer British Airways. As can been seen in the table on the left, the 777-200ER can be powered by several engines. Every operator has the option to select either Pratt & Whitney, Rolce Royce or General Electric manufactured powerplants with each differing in engine thrust. Air France was the first airline to take delivery of a -200ER powered by GE90-94B engines capable of producing 94.000 lbf of thrust. Worldwide the Rolce Royce Trent 800 is the leading engine for the 777 as its market share on this particular airframe is well over 40 percent. Although the engine is used on the majority of 777-200s, it is not available for the 777-200LR and -300ER.
On April 2 1997, a Malaysian Airlines Boeing 777-200ER set a world record by flying a total distance of 20.044 km from Boeing Field, Seattle to Kuala Lumpur, Malaysia without landing. The flight was completed in 21 hours and 23 minutes. As it was a non-revenue flight there were no passengers or any other payload on board the aircraft. Besides this, the airplane is known for its longest ETOPS-related emergency flight diversion conducted by a United Airlines Boeing 777-200ER while flying over the Southern Pacific with approximately 255 passengers onboard on March 17, 2003.
Compared to other 777 models, the 777-200ER is the best selling model so far, with over 420 aircraft already sold. It faces direct competition from the Airbus A340-500 and the future Airbus A350-900.

| Boeing 777-200ER Design |
| The Boeing 777 is one of the most technically advanced aircraft in use today. In fact, it is the largest twinjet aircraft able to carry between 301 and 368 passengers in a three class configuration over a distance of 9.000 nautical miles. Some distinguised features of the 777 are its six wheels on each main landing gear, circular fuselage cross section, blade-like tail cone and its giant size engines which are the biggest used in commercial aviation. With the design of the 777, Boeing employed advanced technologies which include a fly-by-wire flight control system, Electronic Flight Bag (EFB), fiber optic avionics network, LCD glass cockpit flight display (Honeywell), the most powerful turbofan engines on a commercial aircraft and, as stated earlier, the distinctive six-wheel main landing gear. Another option that was offered by Boeing were folding wingtips and was meant to appeal to airlines who would wish to utilize their aircraft in gates made to accomodate smaller sized aircraft. Untill today, no airline has actually purchased this option.
Although the Boeing 777 was fitted with a fly-by-wire control system, Boeing decided to retain conventional control yokes rather than a side-stick which is used in many fly-by-wire fighters and Airbus aircraft. Boeing's vision was that control yokes were more intuitive for pilots and would not require any adjustment. Furthermore, the Boeing 777 is operated by a crew of two without the need for an additional flight engineer.
| The cabin of the 777 is fitted with the so-called Boeing Signature Interior which has since been used on other aircraft like the Boeing 767-400ER, 747-400ER, 737NG (partly) and 757 (partly). Furthermore, the 777 features larger windows than those on many other aircraft thus enhancing passenger experience. The style of these windows, i.e. more rounded, was later adopted on aircraft like the 767-400ER and 747-8. The spacious cabin also provides crew rest areas located in the crown area above the cabin. Separate crew rests can be included for both flight and cabin crew, with a two-person crew rest above the forward cabin between the first and second doors, and a larger overhead crew rest further aft with multiple bunks. |

| Boeing 777 Versions |
Boeing 777-200 |
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 |
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 |
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 |
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 |
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 |
