Boeing 777-200LGW(LR)

When developing the 777, Boeing offered it for two conventional types of market. The aircraft intended for market “A” had a flight range in the range of 8000-9000 km and could be used on the North Atlantic routes connecting Europe with the United States. Market “B” required an airplane with a flight range of 11,000–13,000 km, which is typical of many trans-Pacific airlines and routes between European cities and the US west coast. The original 777-200 is just for market A. Aircraft Boeing 777-200LGW (sometimes referred to as Boeing 777-200B), which meets the conditions of the market “B”, was created by the company in 1992 – 1996. to compete in the market with the European long-range aircraft Airbus Industry A340-300.

The aircraft made its first flight in the fall of 1996, and at the beginning of 1997 went into operation. On March 31 – April 2, 1997, the 777-2001GW aircraft made a record round-the-world flight on the Seattle-Kuala Lumpur-Seattle eastward flight with one intermediate landing in Kuala Lumpur (Malaysia). A flight of 37,344 km was completed in 41 hours 59 minutes. (including parking in Kuala Lumpur for 1 h 57 min.). At the Seattle – Kuala Lumpur stage, a new world record of the non-stop eastward flight was set for the 20043 km passenger aircraft. The previous record (19008 km) was set in June 1993 on an Airbus Industry A340-200 aircraft on the route Paris – Auckland (New Zealand), when the first such round-the-world flight was carried out. That flight lasted 48 hours 22 minutes.

Boeing is considering the possibility of further increasing the take-off mass of the aircraft up to 299 – 313 tons, but for this option, it will require turbofan engines with thrust in class 38 – 39 tons. The aircraft is equipped with an EFIS digital avionics system manufactured by the American company Honeywell with five flat color liquid crystal displays output of flight information, a digital system for monitoring the operation of on-board systems and the power plant EICAS (three flat liquid crystal displays), an “electronic library” with a database of all aircraft systems and equipment. There is an on-board system for diagnosing the condition of on-board systems. A TCAS flight collision avoidance system is installed on the aircraft. All avionics comply with the ARINC 629 standard. It has been mass-produced since 1996. The price of the aircraft is about 135-153 million dollars.

Later, the LGW model was replaced by the 777-200LR, which is a long-range wide-body aircraft, one of the longest-range airliners on the planet.

Boeing 777-200LR (Longer Range) able to take on board from 314 to 440 passengers and carry them to a distance of up to 17.370 km. In November 2005, the aircraft set a world record (in the Guinness Book of Records), flying 21.602 km without landing, from Hong Kong to London in 22 hours 42 minutes. Thanks to the aircraft’s ability to connect virtually any two continents, Boeing named this model the Wordliner.

In the process of creating the liner, special attention was paid to the wishes of passengers. According to Boeing, thanks to this, the liner turned out to be the most consumer-oriented in the world. The 777-200LR is designed in the style of a Boeing Signature Interior with larger luggage racks and indirect lighting to provide comfort for a long flight. The width of the cabin (5.87 meters) allows you to accommodate up to 10 seats in a row. The size of the windows is 380*250 mm. Since the aircraft is designed for super long flights, many airlines equip the cabin with multimedia entertainment systems.

The first flight of the 777-200LR took place in November 2005, and its commercial operation began in February 2006. The main competitor of the liner is the Airbus A340-500HGW.

This Wordliner honorary title has earned the Boeing 777-200LR super long-range aircraft, which can connect any two airports in the world in one non-stop flight. The Boeing 777-200LR has become an improved version of the Boeing 777-200ER. And it was the B777 200LR that set a record in commercial aviation, flying 17,370 km without refueling. The sale of Boeing 777-200LR aircraft is in demand by every major airline, which is interested in offering its customers the opportunity to make the longest non-stop flights in the world with maximum comfort.

Dallas-Tokyo or Los Angeles-Singapore there is nothing complicated for those who choose flights on the Boeing 777-200LR passenger airliner. Extra-long routes between the main airports of the world are the prerogative of this modification of the B777 Wordliner. The range of flights on the Boeing 777-200LR passenger airliner in the standard cabin layout is 17,395 km. Most often, the B777-200LR serves flights between such pairs of cities: New York Auckland, Chicago-Sydney, Perth-London, Miami-Taipei, New York-Singapur. In this case, the flight lasts about 19 hours. A longer flight implies increased comfort for long-distance passengers. Because of this, the Boeing 777-200LR is equipped with a multimedia entertainment system to brighten up a long journey. The three-class version of the Boeing 777-200LR can comfortably accommodate 301 passengers. The maximum number of passengers in a single-class configuration is limited to 440 seats. At the same time, regular flights over such long distances often turn out to be half empty, so passengers often get even more personal space in the spacious Boeing 777-200LR. Soft lighting, a quiet interior, wide comfortable seats, and the ability to adjust the seats eliminates fatigue at the end of the route. The cruising speed of the B777-200LR is 905 km / h, and the maximum possible 950 km / h.

The model was developed almost at the same time as the B777-200ER, but as a result, received three additional fuel tanks in the rear cargo compartment and a naturally increased take-off weight. Three tanks allow you to fill up to 202 570 liters of fuel and thereby ensure maximum flight range. The take-off weight of the model is 347,800 kg.

Distinctive features of this ultra-long-haul model are the reinforced glider design, slightly beveled wingtips, and updated landing gear. The power plant on the Boeing 777-200LR is similar to the B777-200ER two turbojet engines from General Electric GE90-115BL with a thrust of 52,300 kgs or GE90-110B1 with a lower thrust of 49,940 kgs. Selling aircraft of an earlier year of production may be cheaper due to the installation of a second configuration of engines.

The 3.9 m extension of the wingtips in the Boeing 777 200LR is identical to the design of this part in the 777F and Boeing 777-300ER. With the same passenger capacity, the span and a wing area of ​​the Boeing 777-200LR are larger than that of the Boeing 777-200ER – 436.8 square meters and 427.8 square meters, respectively. The wingspan is also increased due to the mentioned tips to 64.8 m. The length of the B777-200LR is 10.2 m less than the B777-200ER. The closest competitor to the modification is the Airbus A340-500HGW.
