777-200ER

The 777-200ER ("ER" for Extended Range), the B-market version of the -200, was originally known as the 777-200IGW for its increased gross weight.[72] The -200ER features additional fuel capacity and an increased maximum takeoff weight (MTOW) over the -200.[169] Aimed at international airlines operating transatlantic routes,[18] the -200ER's maximum range is 7,700 nautical miles (14,300 km).[169] In addition to breaking the eastbound great circle "distance without landing" record, the -200ER also holds the record for the longest ETOPS-related emergency flight diversion (177 minutes under one engine), on a United Airlines flight carrying 255 passengers on March 17, 2003, over the Pacific Ocean.[172][173]

The first -200ER was delivered to British Airways on February 6, 1997.[73] Singapore Airlines, one of the type's largest customers,[1] ordered over half of its -200ERs with reduced engine thrust specifications (de-rated) for use on medium-length routes.[174][175] The de-rated engines lower MTOW, which reduces the aircraft's purchase price and landing fees, and can be re-rated to full -200ER standard for long-haul operations.[174] As of August 2013, -200ER deliveries to 33 different customers totaled 422.[1] As of July 2013, 418 examples of the -200ER were in airline service.[170] The competing aircraft from Airbus
