Narrative:
During IOE, level at FL180, we changed from an ILS to a CAT IIIA ILS autoland for training purposes. During the briefing, we were given a lower altitude with a continued descent to approach altitude. No one caught the fact that our altimeters were still at 29.92. This was corrected at approximately 3000 ft MSL. No mention was made by ATC. The change in control put us out of our normal sequence.

Title: FLC OF A B737-300 FORGOT TO RESET THEIR ALTIMETERS LEAVING FL180 AND DID NOT CATCH THEIR MISTAKE UNTIL LEVELING AT 3000 FT PRIOR TO STARTING A CAT III ILS APCH.
Narrative: DURING IOE, LEVEL AT FL180, WE CHANGED FROM AN ILS TO A CAT IIIA ILS AUTOLAND FOR TRAINING PURPOSES. DURING THE BRIEFING, WE WERE GIVEN A LOWER ALT WITH A CONTINUED DSCNT TO APCH ALT. NO ONE CAUGHT THE FACT THAT OUR ALTIMETERS WERE STILL AT 29.92. THIS WAS CORRECTED AT APPROX 3000 FT MSL. NO MENTION WAS MADE BY ATC. THE CHANGE IN CTL PUT US OUT OF OUR NORMAL SEQUENCE.
