Ops to Russia and Russia Far-East
767-300ER,
I fly the ER to Moscow and via RFE (trans-Sibera) routes between ANC-ICN. Our altimeters do not have metric...we use conversion charts provided by Jeppesen (Ch. 5, tables & codes). The PM reads back the metric alt to ATC, the RP states the equivilent in feet, and the PF puts it in both the MCP alt window and the FMS. As a technique, the PM also puts the metric altitude in the VOR course select window. The FMS will take the altitude in feet to tens of feet.
We do not use QFE at Moscow. Using QFE means you cannot use VNAV and you cannot use EGPWS. Moscow will give you a QNH on request. Also, the ACARS current weather has QNH on it as a quality check tool.
The Jepp charts for Moscow have everything you need to fly either a QNH or a QFE approach.
