OAK Arrival and SFO Departure Jet Traffic: Montclair Flight Track Analyses, HMMH Inc.,
Technical Memorandum HMMH Project Number 302551.004, March 30, 2016.)
This graphic is from a report commissioned by the Noise Forum and contrasts Oakland Arrival and San Francisco Departure Jet Traffic over the East Bay for Pre NextGen traffic conditions and Post NextGen Traffic conditions.
The map on the left shows that planes were previously dispersed broadly over the East Bay as shown by the yellow color indicating a Medium Density of Flights for most of the area. Such dispersion more equitably spread airplane noise. The map on the right shows conditions after Nextgen and reveals how many areas had much of their overflying traffic eliminated (turned into a blue green to pale yellow color). The narrow deep orange color lines in the Post NextGen conditions on the right show how traffic was concentrated into tight corridors that slammed certain areas – especially areas in the East Bay Hills that now experience concentrated SFO Departure traffic flying on top of concentrated Oakland arrivals over their homes (the crisscrossed, deep orange lines).
Flight Corridor Map
Map view of new flight tracks implemented under NextGen. WNDSR is the new corridor for planes arriving from the north and east into Oakland Airport (blue lines). Once planes on WNDSR get near Anthony Chabot Regional Park, Air Traffic Control disperses them over a large area before turning them into their landing at the airport. TRUKN is the new corridor for planes departing SFO to the east (red lines). Planes fly to the Oakland Airport; and from there, are directed to one of four paths heading eastward.
Flight paths for Oakland departures to the north and east are not included on this map. These flights are dispersed over the East Bay and do not follow a pre-set corridor. Night time departures from SFO and OAK between the hours of 10pm and 7am are supposed to use special noise abatement tracks that go up the Bay to Point Richmond before turning eastward. There is no noise abatement track for night time arrivals into Oakland, which include significant numbers of nightly UPS and FedEx cargo planes flying into their major west coast hubs at this airport.
