Boeing 777-300ER

role : wide-body airliner

importance : ****

first flight : operational : May 2004 (Air France)

country : United States of America

production : 837 aircraft at Everett, Washington

general information :

10.2m longer than the -200. Can carry 365 passengers over 14594 km.

Has raked wingtips which increases the wingspan by 1.98m. The fuselage and wings are strengthened and the main landing gear is modified. It is powered by the 513 KN GE90-115B turbofan, the world’s most powerful jet engine. It is a direct competitor of the Airbus A340-600 and A350-1000. Airlines required the 777-300ER as replacement for its 747-400’s giving a 20% fuel burn saving. Operating cost per seat hour : 44 USD (total DOC 26000 usd/hour). 777-300ER value at its peak : 150 mln USD. The 777-300ER was the best selling 777 variant.
