Narrative:

Incorrectly set 29.92 in the altimeter instead of 0992 millibars. The copilot read back 29.92, and the error was not caught by ATC, the relief pilot, or myself. I knew the readback didn't sound right, but soon after we got busy with altitude changes, heading changes, and frequency changes. As we reached the (assigned altitude), we did not catch the error until on the localizer -- about to intercept the GS. We were informed by ATC of the error as we were already intercepting the localizer. Also, flight was on frequency, which added to the confusion.

Title: ON APCH TO EGLL, B767 FLC CAPT INPUT INCORRECT ALTIMETER CAUSING ALT OVERSHOOT.

Narrative: INCORRECTLY SET 29.92 IN THE ALTIMETER INSTEAD OF 0992 MILLIBARS. THE COPLT READ BACK 29.92, AND THE ERROR WAS NOT CAUGHT BY ATC, THE RELIEF PLT, OR MYSELF. I KNEW THE READBACK DIDN'T SOUND RIGHT, BUT SOON AFTER WE GOT BUSY WITH ALT CHANGES, HDG CHANGES, AND FREQ CHANGES. AS WE REACHED THE (ASSIGNED ALT), WE DID NOT CATCH THE ERROR UNTIL ON THE LOC -- ABOUT TO INTERCEPT THE GS. WE WERE INFORMED BY ATC OF THE ERROR AS WE WERE ALREADY INTERCEPTING THE LOC. ALSO, FLT WAS ON FREQ, WHICH ADDED TO THE CONFUSION.
