I fly to several Russian cities. Some are more "advanced" ATC wise than others.
I believe metres are going and feet are coming in. Either way, that was a potential source of fun and games.
QFE is used instead of QNH.
Do not expect a nice line up onto the ILS. You'll be given a 90 degree intercept and it's up to you to turn onto it.
If you're expecting your SID or STAR in good time, forget it. You're likely to be given it just as you're lining up or half way through the arrival. If in doubt, fly what's filed. If it's a different rwy to what you were expecting, ask early.
In Moscow expect a lot of frequency changes shortly after departure. Climb at a sensible rate so you don't level bust.
If you have a technical problem, for heaven's sake, don't tell them over the RT. Just say you need to return etc. Otherwise, you'll have a mountain of paperwork to fill in and your a/c won't be released for days.
If any Russian leader's flying. You won't be. Take extra fuel. Be patient.
Their definition of braking action is interesting. Expect it to be worse than advertised. Expect the taxi ways to be impersonating ice rinks. Fun times. But they do work quickly at sorting it.
If you get told "no flight plan in system" - it means one of two things. 1. Immigration hasn't sent the approval - call the Handling agent. 2. You're a few too many "down the screen" and he/she can't see your plan.
Be patient - did I mention that? The people are fine. Be understanding and pleasant to them. Don't what ever you do open the door before Immigration has turned up.
Haha that sounds pretty messed up! SVO is the WORST airport I have ever been to as a passenger. I'ld imagine Bangladesh airports have better organization of things... it's like things are deliberately made super difficult to figure out! From your description as a pilot it paints an all too familiar picture I must say!
Hopefully some day things get better
