Hey, we are on an aircraft for the next 14 hours and some odd minutes so what else is there to talk about? Oh yeah and we lose a day, where did it go? We arrive in China 5 hours 5 minutes and one day from takeoff... weird...
A340-600 China Eastern Airbus A340-600 in Expo 2010 livery
Designed as an early generation 747 replacement, the A340-600 flies 380 passengers in a three-class cabin layout (419 in 2 class) over 7,500 nautical miles (13,900 km). It provides similar passenger capacity to a 747 but with 25% more cargo volume, and at lower trip and seat costs. First flight of the A340-600 was made on 23 April 2001. Virgin Atlantic began commercial services in August 2002.The A340-600 is more than 10 m longer than a basic -300, more than four metres longer than the Boeing 747-400 and 2.3m longer than the A380. It held the record for being the world's longest commercial aircraft until February 2010 with the first flight of the Boeing 747-8. The A340-600 is powered by four 56,000 lbf (249 kN) thrust Rolls-Royce Trent 556 turbofans. It also has an additional four-wheel undercarriage on the fuselage center-line to cope with the increased MTOW. Airbus has made provisions for freeing additional upper deck main cabin space by providing optional arrangements for additional facilities such as crew rest areas, galleys, and lavatories upon the "stretched" A340 aircraft's lower deck.
