Russian Emergency Landing
Wouldn't it be possible to just correlate measured actual fuel flow, whatever the actual drag might be, speed/distance and range prediction? Higher drag and shorter range could be expected, but wouldn't this be a great use of moving maps available in non-normal situations?
So what we are saying is..... Not only did the crew incorrectly calculate the fuel required for a gear-down diversion to Novosibirsk, but they also incorrectly calculated the landing distance required with a G HYD failure at Omsk which precipitated the flawed diversion decision in the first place! They really did not do very well.
Same answer?
A temporary runway should be possible, even if the ground is quite soft. If the damage is minimal I don’t see why it can’t make it out, and there’s precedent for such takeoffs.
Is there a real problem with flying this aircraft out asuming
1 Its landing gear and engines have not been badly damaged
2 Hard enough surface and enough of it -
3 All grass and bushes etc cut down to stop FOD on the take off roll.
I imagine if they can flatten the take off path and wait until late Novermber -it will be frozen, they might screw up hi tech stuff but the Russians are usually pretty good at dealing with harsh environments as they have a lot of them

I wish them well ... but having watched grain trucks loaded with just 28 tonnes of grain (40+ tonnes GCM) progress across the field to the nearby road and observed the tyres sinking into the soil with just this load spread over five axles and twenty load bearing wheels, I'm nervous. The rolling resistance here could be quite serious.
Everything will depend on the pre-existing compaction of the 'runway' and how much real estate is available in a direction which provides a nice long into wind excursion. The wheel marks left on the landing run are notable, however it was loaded at that point. It should therefore be much lighter for an attempted departure, but this is offset to some degree by the weight of the fuel needed to get to an anticipated destination - assuming aviation can be achieved. I am sure all of this will be considered, and perhaps there is an intention to roll the working area to further compact the soil profile, One other issue is whether the remnant vegetation will remain sufficiently anchored to the surface not be ingested into the engines. It looks like it was a grain crop of some kind. 'Twill be interesting ....

Roll the VR length flat, wait for it to freeze deep enough to support the gear and clear off the snow.
