Narrative:

Passing 22000 descending, I obtained the ATIS. The altimeter was 28.84. I started to write 'low' but remembered enlarging the 8's with 2 circles on top of each other thinking this would be sufficient in drawing attention to the low altimeter setting. Like many approachs into anc, we were descending rapidly. The captain flew over the OM while maintaining 2000 ft. We felt we should have began picking up the GS. About this time, the captain called for the copilot to advise tower we were going missed approach. Simultaneously we broke out of the overcast and the copilot called runway in sight. The captain corrected to intercept the GS and made a normal landing. 2 days later my captain called and informed me that the next crew after our flight had noticed, after going through their checks and sitting ready to go in the aircraft for 20 min, an altimeter discrepancy. The copilot found the altimeter to be 29.84 instead of the actual 28.84 setting. This incorrect altimeter setting matches up with several of the flight and instrument oddities that we experienced. Recommendation to help prevent a future occurrence: if any special attention is directed toward an altimeter setting, write it on the copied ATIS card. (Ie, write 'low'). Also verbally draw attention to an unusual ATIS altimeter setting.

Title: WRONG ALTIMETER SETTING. FLC SET 29 PT 84 INSTEAD OF ACTUAL HG OF 28 PT 84.

Narrative: PASSING 22000 DSNDING, I OBTAINED THE ATIS. THE ALTIMETER WAS 28.84. I STARTED TO WRITE 'LOW' BUT REMEMBERED ENLARGING THE 8'S WITH 2 CIRCLES ON TOP OF EACH OTHER THINKING THIS WOULD BE SUFFICIENT IN DRAWING ATTN TO THE LOW ALTIMETER SETTING. LIKE MANY APCHS INTO ANC, WE WERE DSNDING RAPIDLY. THE CAPT FLEW OVER THE OM WHILE MAINTAINING 2000 FT. WE FELT WE SHOULD HAVE BEGAN PICKING UP THE GS. ABOUT THIS TIME, THE CAPT CALLED FOR THE COPLT TO ADVISE TWR WE WERE GOING MISSED APCH. SIMULTANEOUSLY WE BROKE OUT OF THE OVCST AND THE COPLT CALLED RWY IN SIGHT. THE CAPT CORRECTED TO INTERCEPT THE GS AND MADE A NORMAL LNDG. 2 DAYS LATER MY CAPT CALLED AND INFORMED ME THAT THE NEXT CREW AFTER OUR FLT HAD NOTICED, AFTER GOING THROUGH THEIR CHKS AND SITTING READY TO GO IN THE ACFT FOR 20 MIN, AN ALTIMETER DISCREPANCY. THE COPLT FOUND THE ALTIMETER TO BE 29.84 INSTEAD OF THE ACTUAL 28.84 SETTING. THIS INCORRECT ALTIMETER SETTING MATCHES UP WITH SEVERAL OF THE FLT AND INST ODDITIES THAT WE EXPERIENCED. RECOMMENDATION TO HELP PREVENT A FUTURE OCCURRENCE: IF ANY SPECIAL ATTN IS DIRECTED TOWARD AN ALTIMETER SETTING, WRITE IT ON THE COPIED ATIS CARD. (IE, WRITE 'LOW'). ALSO VERBALLY DRAW ATTN TO AN UNUSUAL ATIS ALTIMETER SETTING.
