Boeing 777S: Safe, Reliable, Comfortable and Efficient

The Boeing 777s is considered by aviation expert to be one of the most successful lines of aircraft in the world aviation history. Nearly 1,000 Boeing 777 planes fly millions of kilometres a year. The success of this line is the result of many superior features that promote safety, reliability, comfort and efficiency.

The Boeing 777 is one of the safest airliners in the world today with more than 19 million safe flying hours (by 2008) without any loss of life since its first flight in 1995.

There are many reasons for the B777's safety superiority. First, the Boeing 777 received a record investment by Boeing during its design phase. It is the first airliner entirely designed on computer and assembled in simulation based on a three-dimensional CAD system known as CATIA. Second, for the first time in history, Boeing 777 was designed based on the requirements of airlines as well as the incorporation of the latest technologies from the parts and spares producers around the world. The Boeing 777 has passed all of the toughest tests of time. It is certified by the Joint Aviation Authorities of Europe (JAA) and the US Federation Aviation Administration (FAA) for its airworthiness and reliability.

The Boeing 777 is the first airliner to apply advanced technologies and materials like composity (accupying 9% of its total weight), fly-by-wires and flight envelope protection (a system that guides pilot inputs within a computer calculated framework of operating parameters, acting to prevent stalls and overly stressful manoeuvres). This leads to its better anti-shock properties in turbulent zones, energy saving and noise-reduction. Moreover, the craft is also one of the most comfortable airliners with large windows (the largest before B787), larger overhead bins, indirect lighting and numerous other utilities, depending on airlines' specifications and choices.

With the need to expand its routes to America, Europe and Australia, Vietnam Airlines has developed its fleets by employing this state-of-art airliner since the very first days it was introduced to the market. To date, Vietnam Airlines has been operating 10 Boeing 777-200R (the most preferred variant of the Boeing 777 families), of which four are fully owned (using PrattWhittney PW 4090 engines) and sixe are on lease (using GE90 engines). All have a maximum load capacity of 50 tons and range of 14,000km. All of the 10 Boeing 777s have ETOPS capacity (extended operation with the craft engine) up to 180 minutes, allowing them to fly for an extended three hours to reach a distance of 2,110km, equivalent to the distance between Hanoi and Shanghai.

To bring passengers the best services, all of the 10 Boeing 777s are equipped with Audio/Video-on-Demand systems with personal touch-creems. The entertainment systems offer 10 dramas, 12 short films and other games and music programs. They also give the most advanced AirShows by Rockwell/Panasomics to attend to the entertainment needs of passengers of all ages. There are three classes of seating (Business, Deluxe Economy and Economy) with wider seat distances between the rows allowing more comfort to passengers as compaired to other airlines. During the operation of this aircraft, Vietnam Airlines has been continuously improving its entertainment systems and equipment to meet passengers' demands, including the upgrade of C-Class seats in the four fully -owned crafts; the 2011 entertainment system for two Boeing 777s; and updates for the AirShow system for the entir Boeing 777 fleet. Besides, six of the 10 Boeing 777s operated by Vietnam Airlines offer in-flight telecom service, alowing passengers to call to anywhere in the world during the flight.

Boeing 777s are now efficiently operated by Vietnam Airlines with an on-time rate of 99% and an average of 12 hours of operation per day (as per Boeing report for Feb 2012). This places Vietnam Airlines on the list of airlines operating this aircraft at optimal efficiency.
