someone posted something about additional fuel...I am pretty darn sure that additional fuel would not have caused a problem unless for some reason the fuel was not balanced between wing tanks...that is, someone was crossfeeding fuel from one tank to both engines and finally passing the limit of difference between tanks.
Centre Fuel...
That was the fuel I was referring to.
In case of tankering into this airport as only allowed to tank in Moscow (as suggested by this thread) would the crew have taken so much fuel to land with a remaining considerable amount of centre tank fuel?
This could cause a large shift in CG at high nose up attitudes, adding to inherent 737 design problem of its low engines.
Remember this practise is not recommended: landing with CTR fuel.
So my question was would they have considered it if the fuel limitation as described was in effect for their carrier? If so it could be a contributory factor
