Hey guys,
I spend a lot of time flying in russia. Go to UUWW alot and UUDD occasionally.
Here's my .02 cents worth YMMV.
QFE is no big deal. Forget QNH. Once you get to the TL (1500 meters likely) set QFE. Since your altimeter will display metric even better, but if you don't have one there's a nice conversion chart on Euraisa 1/2 enroute. It also has the metric RVSM cruising levels for Russia.
As for arrivals they almost always give you the shorter circuit so pick that one first. Their arrivals tend to be ovals to the final. They will clear you for the approach and if radar vectored or on arrival the intercept will likely be around 90 degrees. That's ok as it is perfectly acceptable even expected that you make you turn to final shallower (more shallow).
Additionally on final you should indicate gear down and ready to land to recieve your landing clearance. A bit like a PAR.
The runways and taxi ways are a little rough, but better than at Petro or perhaps a lot of places in Africa. Follow me cars do drive 60, but the taxi routing is usually quite long.
Beware the Night Flite.
Good Luck
