Other changes to the -200ER is that the panel has more backup in three classic standby instruments. I actually really like the sound of the Pratt & Whitney, It has a more in the past darker engine feel than the high whiners of modern turbofans. They do sound different and not like that painful grinding noise on the GE that sounds like something very expensive is being slowly cut down to size and a dual engine change is imminent. I haven't flown the B777-200ER over a long route yet, but the engines certainly feel smoother and softer, and yes they have far less power than the GE90-115B which is rated at 115,300 lb f (514 kN). And the engine has Full Authority Digital Engine Control (FADEC).įlightFactor have noted that the Boeing 777-200ER PW4090 engines have the correct performance and fuel consumption - sound set - EEC with EPR as primary control parameter - EICAS differences for EPR-controlled engines and the correct FMC performance parameters. The engines Thrust-to-Weight ratio is ~6 - 7. Overall pressure ratio is 32.0:1 - 35.4:, the Bypass ratio is 5.3:1, with the Turbine inlet temperature (TIT) at 707. The Turbine consists of a 2 stage high pressure turbine and a 5 stage low pressure turbine. The Compressor consits of a 1 stage fan, 5 stage low pressure compressor, 15 stage (5 variable) high pressure compressor and the combustors are annular. The third series is a "Two Spool-high bypass" ratio Turbofan, which is 163.1 in (4.14 m) in length. It can power all the 777 versions except the 300ER and 200LR. The third series engine entered service in June 1995 with United Airlines, and was the first jet engine to enter service with 180-minute ETOPS certification. The third family of the PW4000 Series is the 112 inch (2.8 m) diameter fan engine that was developed specifically for Boeing's 777 where it was the launch engine on that airframe. The -200ER is significant because the Pratt&Whitney PW4090 engines are noticeably smaller than those giant GE90-115B turbofans on the -200LR. If the -300ER variant was noticeable because of its long extra length over the -200LR. The aircraft entered service with British Airways on February 9, 1997, and the -200ER variant was and until the -300ER version was released in 2004 the biggest 777 series seller in 422 aircraft being sold. It was Initially named 777-200IGW, but the offical name was the 777-200ER which first flew on October 7, 1996, and received FAA and JAA certification on January 17, 1997. That now takes all the aircraft variants in the Series (Extended) to four.īoeing 777-200 LR - (Boeing Worldliner Professional)Īfter the initial launch of the standard -200 version of the Boeing 777, Boeing quickly developed an increased gross weight variant of the 777-200 with a greater range and payload capability. The biggest thing to note in this new version is that there has been another addition to the "Extended Pack" of variants in the 777-200ER with the Pratt&Whitney PW4090 engine option. Aircraft Update : Boeing 777 Worldliner Pro + Extended Pack V1.6 by Flightfactor/VMAXįlightfactor-VMAX have updated the Boeing 777 Worldliner Professional and the Extended Pack to v1.6.
