Narrative:

We were cleared for runway 5 visual approach. Our airport advisory page advises maintain 2500 ft until abeam the OM, and 2000 ft until intercepting final. While on base, the copilot descended slightly below 2000 ft, to about 1750 ft. I brought this to his attention, and we made the appropriate climb correction. We landed without incident. In the future, I will be more careful to brief the advisory page in the approach briefing. It's a good idea to be 'heads up' for noise abatement. It's becoming more standard at many airports. Sometimes it's mentioned in ATIS. It would also be very helpful if controllers would add any noise abatement restrs to their approach clrncs.

Title: A B737-300 FO DSNDS BELOW THE RECOMMENDED ALT FOR A NOISE ABATEMENT VISUAL APCH AT ORF.

Narrative: WE WERE CLRED FOR RWY 5 VISUAL APCH. OUR ARPT ADVISORY PAGE ADVISES MAINTAIN 2500 FT UNTIL ABEAM THE OM, AND 2000 FT UNTIL INTERCEPTING FINAL. WHILE ON BASE, THE COPLT DSNDED SLIGHTLY BELOW 2000 FT, TO ABOUT 1750 FT. I BROUGHT THIS TO HIS ATTN, AND WE MADE THE APPROPRIATE CLB CORRECTION. WE LANDED WITHOUT INCIDENT. IN THE FUTURE, I WILL BE MORE CAREFUL TO BRIEF THE ADVISORY PAGE IN THE APCH BRIEFING. IT'S A GOOD IDEA TO BE 'HEADS UP' FOR NOISE ABATEMENT. IT'S BECOMING MORE STANDARD AT MANY ARPTS. SOMETIMES IT'S MENTIONED IN ATIS. IT WOULD ALSO BE VERY HELPFUL IF CTLRS WOULD ADD ANY NOISE ABATEMENT RESTRS TO THEIR APCH CLRNCS.
