In ATIS they`ll give you the transition level in meters (normally 1500m or 1800m - 4900f and 5900f accordingly), also they`ll give you both QFE and QNH in hPa (QFE in MM as well).I guess you can request QNH approach but there`s no problem flying QFE.All you have to do is to substract airport altitude (587`) from MSA (I think you know that).And just remember the two heights below the transition - 2600`(800m)- it`s a kind of an aerodrome circle (orbit) height(the first height you`ll be allowed to descend below the transition) and 1700`(500m)- glideslope intersection height.Normally you`ll hear the phrase like "descend 800m QFE 1001mb" you`ll have to repeat it.And we are to tell the ATC the altimeter setting when crossing the transition.
And remember Moscow is a prohibited zone.Normally you`ll get full vectoring but if you`re going downwind on 14L/R and see that a little bit more and you`re gonna cross the line just say that you`re ready to turn base. Normally you`ll be given a heading for LOC capture but they`ll give you just heading ,you won`t hear the permission for capturing like "advise when LOC captured" so you can make a mistake of not arming the VOR/LOC and overshooting (because finally you`ll hear "turn final" but it cis always too late).So if you get a heading with what you can capture the LOC and permission to descend to 500m(1700`) it should be a signal for you to arm VOR/LOC.
On the take-off the first cleared altitude on the MCP should be 2600` and after take-off contact 127.7 as soon as you can (expect a permission to climb and maintain 800m(2600`).Transition altitude - 1000m(3300`).
And you`d better ask your mates who`s been here as they could add a lot to what I said as they see the whole thing from your point of view.You know we are used to things that might seem completely insane to you (Soviet heritage is not easily to get rid of).
