Proposals for Revising Northern California Metroplex – Alameda County/Contra Costa County 26 SAN FRANCISCO INTERNATIONAL AIRPORT PROPOSALS NIITE THREE DESCRIPTION: The NIITE DP (Figure 14) is intended to reduce nighttime aircraft noise to communities along the western and eastern side of San Francisco Bay including Alameda, Oakland, Berkeley and others. The NIITE DP is used by aircraft departing SFO primarily to destinations to the north and northeast. This procedure was intended to overlay, and replace, the prior QUIET DP (Figure 15). It was designed for noise abatement purposes and was charted to have aircraft fly to the REBAS waypoint at Point Richmond to keep aircraft over the water as much as possible during the lower portion of the aircraft climb profile. The QUIET procedure, provided significant nighttime benefit to the hillside residential areas of Oakland, Berkeley and northward was achieved by requiring that climbing aircraft under full thrust remain over the Bay and not turn eastward until at higher altitudes at REBAS intersection by Point Richmond. The NIITE procedure was developed to provide a similar nighttime benefit by overlaying the legacy QUIET procedure. SFO departing aircraft track to HUSSH and from there, track 324° to NIITE thence are charted to track to REBAS at Point Richmond and cross at 8000 feet. This route has aircraft following a path that allows them to remain clear of both the west and east shorelines of San Francisco Bay until reaching a higher altitude, when a turn over land is less disruptive to residents at the REBAS waypoint at Point Richmond.
