Why can’t they just strip the plane down and fly it out with one engine to the nearest airport outside Russia? Edit: Answered my own question. The runway is barely long enough for 777 with two working engines. The asymmetric thrust requires a long, careful takeoff roll until the plane has enough rudder authority to keep it straight.

777 is not designed to take off on one engine. Not even while empty.

  It has enough thrust on one engine to take off empty. But, to expand on my edit, it requires both a test pilot and way more runway than the airport has. Edit: Numbers Empty operating weight: 134,800 kg (297,300 lb) Maximum Takeoff Weight(MTOW): 247,200 kg (545,000 lb) The empty operating weight includes everything needed to fly (including crew) minus useable fuel. So the only additional weight need is fuel.

    The plane in question is a -200LR which has the GE90-115B engines at 115 klbs of thrust. The numbers on that variant are OEW 145t and MTOW of 347t.

      Cool! Thanks for checking my numbers. :)

    it requires both a test pilot No. Keep in mind most commercial operators are going to run derated thrust (a.k.a. flex thrust) for takeoffs to save on maintenance. Engine failure after V1 is regularly practiced. The big problem will be directional stability on the way V2. https://www.infinidim.org/b777-engine-failure-on-takeoff-efato https://www.infinidim.org/b777-engine-failure-on-takeoff-efa... https://www.airliners.net/forum/viewtopic.php?t=747649 https://www.airliners.net/forum/viewtopic.php?t=747649

  Sure it is. Being capable of generating takeoff thrust on one engine and being able to climb on one engine are part of the FAA requirements. You will need more runway, but you don't need a test pilot as planning for obstacles you may not be able to clear at an airport is something every commercial pilot has to do.

    Only if it was already past v1 when the engine fails. I don’t think it is required to be able to take off from stop on one engine.
