From SKYbrary Wiki
The Boeing 777-200LR is one of the longest range aircraft in the world at 8,555 nautical miles (15,843 km), even longer than the Airbus A380 and the Boeing 747. But despite being ahead of its time and destined to operate incredible routes, the aircraft never really became successful because of its long-range focus.

The 777-200LR became the world's longest-range commercial airliner when it entered service in 2006. It has a maximum range of 9,395 nm17,399,540 m <br />17,399.54 km <br />57,085,105.029 ft <br /> and was intended for ultra-long-haul routes such as New York to Singapore, or Chicago to Sydney - up to about 19 hours flying time.The -200LR features an increased MTOW and the same wing as the 777-300ER. The 777F is a cargo version of this variant. Three optional auxiliary fuel tanks take the baseline fuel tank capacity from 181,289 l to 203,570 l. Other new features include raked wingtips, redesigned main landing gear, and additional structural strengthening. As with the -300ER, the -200LR is equipped with wingtip extensions of 3.90 m. B77L is member of the B777 family of aircraft.

Accidents & Serious Incidents involving B77L
- B77L, Copenhagen Denmark, 2011 (On 17 April 2011, a Boeing 777F bounced three times during an attempted landing at Copenhagen during which the underside of the aircraft was damaged by two tailstrikes. The second occurred during over-rotation for a go around commenced after thrust reverser deployment, with 760 metres of the 3300 metre-long runway remaining. The Investigation observed that a go around initiated after thrust reverser deployment was contrary to an express prohibition in the aircraft type FCOM. It was noted that the aircraft commander was an instructor pilot and that both pilots had less than 200 hours experience on the aircraft type.)
- B77L, Paris CDG France, 2015 (On 22 May 2015, a Boeing 777F augmented crew attempted a reduced thrust daylight takeoff from Paris CDG using a thrust setting based on a weight 100 tonnes below the actual weight after an undetected crew error. The tailstrike protection system prevented fuselage runway contact after rotation attempts but only after a call from an augmenting crew member was full thrust set with the aircraft becoming airborne near the runway end. The Investigation noted poor crew performance but concluded that operator management of the risk involved and the corresponding regulatory oversight had been inadequate in a number of ways.)
