Narrative:

It's the old altimeter story again! A 13 hour flight, fair rest during night. Typhoon in area, good arrival WX. However, low pressure. ATIS gave altimeter setting of 994. Upon changing to approach control, they also gave us 994 qnh. I was flying, and set 29-94 hg in the altimeter instead of hecto pascals of 994. There was not enough conflict resolution in the cockpit to be sure we set 994 not 29.94. I wanted to hear '2'9.94. We tend to get sloppy stateside. Elimination of the first digit, and we are not used to hearing a low hecto setting. We could see the runway 31 at hrg but instead of 2000 ft above ground at OM intercept, we were 900 ft low! The tower controller did call it, and we finally corrected the altimeter and landed uneventfully. Worldwide standardization would help!

Title: INTERNATIONAL OP. ALTIMETER GIVEN IN HECTO PASCALS 994 FLC SET 29 PT 94 HG. WERE 900 FT LOW OVER THE OM.

Narrative: IT'S THE OLD ALTIMETER STORY AGAIN! A 13 HR FLT, FAIR REST DURING NIGHT. TYPHOON IN AREA, GOOD ARR WX. HOWEVER, LOW PRESSURE. ATIS GAVE ALTIMETER SETTING OF 994. UPON CHANGING TO APCH CTL, THEY ALSO GAVE US 994 QNH. I WAS FLYING, AND SET 29-94 HG IN THE ALTIMETER INSTEAD OF HECTO PASCALS OF 994. THERE WAS NOT ENOUGH CONFLICT RESOLUTION IN THE COCKPIT TO BE SURE WE SET 994 NOT 29.94. I WANTED TO HEAR '2'9.94. WE TEND TO GET SLOPPY STATESIDE. ELIMINATION OF THE FIRST DIGIT, AND WE ARE NOT USED TO HEARING A LOW HECTO SETTING. WE COULD SEE THE RWY 31 AT HRG BUT INSTEAD OF 2000 FT ABOVE GND AT OM INTERCEPT, WE WERE 900 FT LOW! THE TWR CTLR DID CALL IT, AND WE FINALLY CORRECTED THE ALTIMETER AND LANDED UNEVENTFULLY. WORLDWIDE STANDARDIZATION WOULD HELP!
