Narrative:

Descent with crossing restr, cross gland at 10000 ft and 250 KTS. So obtained ATIS 30 mins out. He stated the reception was very bad on his communication (both ATIS and company). Passing FL180 I reset my altimeter to 30.38 and read this back to the first officer. First officer corrected me and stated the altimeter was 30.28. We confirmed this on both in-range checklist, completed at FL180, and approach checklist, completed on intercept heading to final. On final at 1600 ft AGL, my localizer and GS became very sensitive. At 1000 ft call my localizer and GS was much too sensitive for 1000 ft. We also encountered a windshear with loss of 15 KTS and this, I thought, was the reason for GS deviation. We broke out at 700 ft indicated altitude. We were actually at 300 ft. Landing was made successfully. Touchdown zone is 98 ft, our altimeter read 600 ft, actual altimeter setting was 29.69. The altimeter setting that was given me was read off an old ATIS card (departure stn) 30.28. This could have been a disaster due to the fact that the old ATIS card was not discarded. It will be from now on. I also contribute some confusion to turbulence and dodging thunderstorms. On all leveloff altitudes we were 500 ft low. ATC never questioned our altitude, or any interim leveloff.

Title: A DSNDING B727 FAILS TO MAKE AN ALT XING RESTR WHEN HIS ALTIMETER IS SET AT TOO HIGH A READING IN INCHES. HE PERFORMS HIS APCH TO IAH WITH THIS MISSET ALTIMETER AND BECOMES VISUAL AT 300 FT AGL, EXPECTING TO BE AT OR NEAR 700-800 FT. ATC HAD NOT ALERTED HIM TO ANY ALTDEVS.

Narrative: DSCNT WITH XING RESTR, CROSS GLAND AT 10000 FT AND 250 KTS. SO OBTAINED ATIS 30 MINS OUT. HE STATED THE RECEPTION WAS VERY BAD ON HIS COM (BOTH ATIS AND COMPANY). PASSING FL180 I RESET MY ALTIMETER TO 30.38 AND READ THIS BACK TO THE FO. FO CORRECTED ME AND STATED THE ALTIMETER WAS 30.28. WE CONFIRMED THIS ON BOTH IN-RANGE CHKLIST, COMPLETED AT FL180, AND APCH CHKLIST, COMPLETED ON INTERCEPT HDG TO FINAL. ON FINAL AT 1600 FT AGL, MY LOC AND GS BECAME VERY SENSITIVE. AT 1000 FT CALL MY LOC AND GS WAS MUCH TOO SENSITIVE FOR 1000 FT. WE ALSO ENCOUNTERED A WINDSHEAR WITH LOSS OF 15 KTS AND THIS, I THOUGHT, WAS THE REASON FOR GS DEV. WE BROKE OUT AT 700 FT INDICATED ALT. WE WERE ACTUALLY AT 300 FT. LNDG WAS MADE SUCCESSFULLY. TOUCHDOWN ZONE IS 98 FT, OUR ALTIMETER READ 600 FT, ACTUAL ALTIMETER SETTING WAS 29.69. THE ALTIMETER SETTING THAT WAS GIVEN ME WAS READ OFF AN OLD ATIS CARD (DEP STN) 30.28. THIS COULD HAVE BEEN A DISASTER DUE TO THE FACT THAT THE OLD ATIS CARD WAS NOT DISCARDED. IT WILL BE FROM NOW ON. I ALSO CONTRIBUTE SOME CONFUSION TO TURB AND DODGING TSTMS. ON ALL LEVELOFF ALTS WE WERE 500 FT LOW. ATC NEVER QUESTIONED OUR ALT, OR ANY INTERIM LEVELOFF.
