Now, if that was their first departure from a Moscow airport, & if you haven't been there yourself, here are a few difficulties you have to face:
Invariably, no SID is given to you, you have to work it out - even asking for confirmation often gets no useful response!
Low temperatures give excellent aircraft climb performance.
SID says max rate climb for noise purposes......
.....but with a low QFE (say 980 Mb to make the maths easy), when you chance to 1013.2, whoops, instant 1000+ ft altimeter climb.
SID/routeing/cleared altitude can sometimes be changed immediately on check-in with first airborne frequency, 4 items of critical information all at once (including next frequency change!).
Numerous frequency changes within very short time, often only 1500 - 3000 ft intervals at lower altitudes.
Language issues - some Moscow ATC transmissions aren't the clearest in the world sometimes, associated with phraseology perhaps unusual to some pilots -
"Climb standard 2000m" = Climb
FL 2000m.
So, it's all happened before in Moscow airspace, & I bet it will happen again on a regular basis!
Now, of course, at Thames Radar .........
