Thành viên:Nvdtn19/nháp2777-200ER.jpg) The B-market 777-200ER ("ER" for Extended Range), originally known as the 777-200IGW (increased gross weight), has additional fuel capacity and an increased MTOW enabling transoceanic routes.[1] With a 658,000 lb (298 t) MTOW and 93,700 lbf (0,41680 kN) engines, it has a 7.065 nmi (13.084 km) range.[2] It was delivered first to British Airways on February 6, 1997.[3] Thirty-three customers received 422 deliveries, with no unfilled orders tính đến tháng 4 năm 2019[cập nhật].[4] Tính đến tháng 7 năm 2018[cập nhật], 338 examples of the -200ER are in airline service.[5] It competed with the A340-300.[6] Boeing proposes the 787-10 to replace it.[7] The value of a new -200ER rose from US$110 million at service entry to US$130 million in 2007; a 2007 model 777 was selling for US$30 million ten years later, while the oldest ones had a value around US$5–6 million, depending on the remaining engine time.[8] The engine can be delivered de-rated with reduced engine thrust for shorter routes to lower the MTOW, reduce purchase price and landing fees (as 777-200 specifications) but can be re-rated to full standard.[9] Singapore Airlines ordered over half of its -200ERs de-rated.[9][10]
