Narrative:
During descent the moscow airport ATIS was copied and understood to include the QFE altimeter setting of 0996 MB. When switched to final approach control with descent out of 'meters standard' to meters, QFE was heard to be and repeated back to approach as 0996 MB. During descent, approach said 'stop descent.' that caused us to check altitude readouts. We had already leveled off at our assigned altitude as indicated by our altimeters. We realized that we were approximately 800 ft too low according to our radar altimeters. We were on the localizer, level below the GS, intercepted the GS and landed. We did have visual contact with the ground while descending and being vectored. After landing we determined that the altimeter setting should have been 0966 MB. I guess that language, communications in russia, the meter altitudes, the QFE, the low transition altitude, checklists, FMS clean up, checking localizer intercept course on ILS mode, short vectors all contributed to the error. As an example of communication and language problems all 3 of us heard the tower frequency on ATIS and approach control to be 121.5 when according to the charts it is 131.5. Supplemental information from acn 407404: descending into moscow, russia, we briefed extensively the use of QFE altimetry and at what the transition level was for its employment. On ATIS I believe I heard a QFE altimeter setting of 996 MB. The first officer was advised by moscow approach of the QFE altimeter, he read back 'altimeter 996 MB QFE.' while on the runway I noticed the altimeters showed approximately 800 ft when they should have shown '0.' I asked the first officer to turn his altimeter setting down until it read 0 ft. The altimeter setting at 0 was 966 MB. We had set 996 MB instead. Because we only use QFE altimetry in russia, the setting of 996 MB did not strike us as odd.

Title: A DSNDING B767-300 FLC SETS THE WRONG MILLIBARS IN THEIR ALTIMETERS AND DSNDS 800 FT BELOW THEIR ASSIGNED ALT ON APCH. THE MOSCOW APCH CTLR STOPS THEIR DSCNT AT 900 FT AGL. CREW CITES POOR ATIS AND APCH CTL INFO RELATED TO LANGUAGE BARRIER.
Narrative: DURING DSCNT THE MOSCOW ARPT ATIS WAS COPIED AND UNDERSTOOD TO INCLUDE THE QFE ALTIMETER SETTING OF 0996 MB. WHEN SWITCHED TO FINAL APCH CTL WITH DSCNT OUT OF 'METERS STANDARD' TO METERS, QFE WAS HEARD TO BE AND REPEATED BACK TO APCH AS 0996 MB. DURING DSCNT, APCH SAID 'STOP DSCNT.' THAT CAUSED US TO CHK ALT READOUTS. WE HAD ALREADY LEVELED OFF AT OUR ASSIGNED ALT AS INDICATED BY OUR ALTIMETERS. WE REALIZED THAT WE WERE APPROX 800 FT TOO LOW ACCORDING TO OUR RADAR ALTIMETERS. WE WERE ON THE LOC, LEVEL BELOW THE GS, INTERCEPTED THE GS AND LANDED. WE DID HAVE VISUAL CONTACT WITH THE GND WHILE DSNDING AND BEING VECTORED. AFTER LNDG WE DETERMINED THAT THE ALTIMETER SETTING SHOULD HAVE BEEN 0966 MB. I GUESS THAT LANGUAGE, COMS IN RUSSIA, THE METER ALTS, THE QFE, THE LOW TRANSITION ALT, CHKLISTS, FMS CLEAN UP, CHKING LOC INTERCEPT COURSE ON ILS MODE, SHORT VECTORS ALL CONTRIBUTED TO THE ERROR. AS AN EXAMPLE OF COM AND LANGUAGE PROBS ALL 3 OF US HEARD THE TWR FREQ ON ATIS AND APCH CTL TO BE 121.5 WHEN ACCORDING TO THE CHARTS IT IS 131.5. SUPPLEMENTAL INFO FROM ACN 407404: DSNDING INTO MOSCOW, RUSSIA, WE BRIEFED EXTENSIVELY THE USE OF QFE ALTIMETRY AND AT WHAT THE TRANSITION LEVEL WAS FOR ITS EMPLOYMENT. ON ATIS I BELIEVE I HEARD A QFE ALTIMETER SETTING OF 996 MB. THE FO WAS ADVISED BY MOSCOW APCH OF THE QFE ALTIMETER, HE READ BACK 'ALTIMETER 996 MB QFE.' WHILE ON THE RWY I NOTICED THE ALTIMETERS SHOWED APPROX 800 FT WHEN THEY SHOULD HAVE SHOWN '0.' I ASKED THE FO TO TURN HIS ALTIMETER SETTING DOWN UNTIL IT READ 0 FT. THE ALTIMETER SETTING AT 0 WAS 966 MB. WE HAD SET 996 MB INSTEAD. BECAUSE WE ONLY USE QFE ALTIMETRY IN RUSSIA, THE SETTING OF 996 MB DID NOT STRIKE US AS ODD.
