What is a noise abatement procedure?
A noise abatement procedure is a recommended flight path aircraft follow to minimize noise over a populated area. Because this is a recommended procedure, pilots may decline to follow it due to safety concerns or operating limitations. For some noise abatement procedures, a pilot must be able to see specific visual cues. If the visual cues are not visible, the pilot will not be able to safely follow the noise abatement procedure. Other procedures rely on navigational equipment capabilities.
Can the Port of Oakland change flight paths?
No. The FAA controls and regulates the airspace. Any change in departure or arrival flight paths must be approved and implemented by the FAA. The noise office is here in large part to help communicate between the airport, FAA and local community.
What happens to my aircraft noise complaint?
The Noise Management Office will log your complaint in the complaint database. The Noise Management Office investigates all complaints by new callers and callers who desire specific information about noise events and aircraft activity. When appropriate, staff follows up with aircraft operators and/or the FAA to investigate what action can be taken to minimize noise in the future. Although all aircraft noise complaints are documented and routinely reported, noise office staff does not typically investigate every complaint made by frequent callers due to the often repetitive nature of the complaint.
What information do I provide in my noise complaint?
The Noise Management Office documents noise complaints by obtaining information from the caller about the nature of the complaint, time of the occurrence and location of the caller’s residence. Date and time are most critical. Staff uses this information to determine the probable activity responsible for the complaint and, when requested, provides a report or a letter to the caller.
Why do some aircraft seem louder than others?
Aircraft operating at Oakland International Airport have a diverse range of noise levels. These noise levels primarily depend on the type of engine used by the aircraft, the size of the aircraft and whether the aircraft is taxiing on the airfield, landing or taking off. The newest so called "full Stage 3" aircraft tend to be the quietest aircraft in the fleet. Aircraft that were originally Stage 2 compliant but retrofitted to meet Stage 3 regulations tend to be the loudest. Departures tend to be louder than arrivals since the pilot is forcing more power to the engine to achieve lift.
Who tells the pilots where and when to turn?
Commercial pilots fly prescribed routes and general aviation pilots also fly prescribed routes as well as visual flight procedures (VFR) to and from Oakland International Airport as instructed by air traffic controllers. The FAA is responsible for managing Oakland’s airspace and for ensuring the safe and expeditious flow of traffic. The Port of Oakland is responsible for operating and maintaining airport facilities and for ensuring that runways (and taxiways and other facilities) are in good working conditions, meet FAA regulations and are available for use.
Why was I woken up last night by aircraft noise; what’s going on at the Airport?
Like most commercial airports in the US, Oakland International Airport operates 24 hours per day 365 days per year. There is no nighttime curfew at Oakland International Airport. However, the Port of Oakland, in coordination with the FAA, airport users and community representatives, has developed preferred nighttime aircraft procedures that help mitigate aircraft noise over residential areas. Wind and weather permitting, these procedures are designed to keep aircraft over the bay and away from residential areas as much as possible.
What is the difference between North Field and South Field?
South Field, which is defined as the Airport area south of Ron Cowan Parkway, is comprised of passenger facilities, including Terminals 1 and 2, and air cargo facilities, the largest of which is the FedEx Metroplex (their west coast hub operation). North Field (the Airport area north of Ron Cowan Parkway) contains a variety of aviation land uses. The largest is general aviation, including aircraft hangars, ramps, and two fixed base operators: KaiserAir and Signature Flight. North Field also accommodates some air cargo facilities.
Do I qualify for sound insulation?
Oakland International Airport has completed the sound insulation program in the city of Alameda and San Leandro.More information on the sound insulation program, including what noise levels qualify, can be found here.
Why do aircraft sound louder at night than they do during the day?
Nighttime noise events seem louder because the ambient noise is lower. More noise events may be noticed at night compared to daytime hours when there exists a higher ambient noise level.
Tell me more about Oakland International Airport?
Oakland International Airport (OAK) is a primary commercial service airport with four runways: one primary air carrier runway at South Field (Runway 12-30) and three runways at North Field (Runway 10R-28L, Runway 10L-28R, and Runway 15-33). The Airport is served by several passenger and cargo airlines. In calendar year 2016, OAK accommodated 12.1 million annual passengers (enplaning plus deplaning) and was the 40th busiest in the U.S. in terms of total passengers, according to Airports Council International-North America.
What are the anticipated aircraft noise impacts at Oakland International Airport in the future?
The noise impact area for the Oakland Airport has decreased during the past decade and is expected to continue to decrease as a result of newer and quieter technology aircraft. Development of the next generation of aircraft (Stage 4) is well underway and will bring quieter planes in the future.
How does the Port of Oakland track and monitor flights?
The noise management office uses software called ANOMS, which stands for Airport Noise and Operations Monitoring System. This system collects noise data from sixteen remote noise monitoring terminals and portable noise monitoring equipment in addition to flight track data from the FAA. It is the main tool used by the noise office to research complaints and to monitor noise abatement procedures and programs.
Why have aircraft flight paths changed?
Winds in the Bay Area predominantly blow from the west to the east. With winds from the west, the North Flow air traffic pattern (referred to as the “West Plan”) is in effect. When wind direction in the Bay Area reverses and is from the southeast, the South Flow air traffic pattern (referred to as the “Southeast Plan”) is in effect. The FAA alters the traffic pattern to the Southeast Plan when weather conditions such as winter storms shift the wind direction. Historical data collected for the years 1999-2001 by the Airport Noise Management Office demonstrate that 91.5 percent of all arrivals and departures occur when the Airport is operating in the West Plan, which generally involves arrivals from the south and departures to the north. Because arrival and departure patterns differ under the two plans, noise related to aircraft events is experienced differently depending on which plan is in effect. Under West Plan conditions, areas to the north of the Airport experience noise related to departing aircraft, whereas areas to the south experience aircraft arrival noise. Under the Southeast Plan, the opposite effects occur.
What is the Southeast Plan?
The Southeast Plan is perceived by the public as a dramatic change in the air traffic patterns. The change generates public reaction and aircraft noise complaints. Below are flight track maps displaying Bay Area air traffic patterns associated with Oakland International Airport (OAK), San Francisco International Airport (SFO), and San Jose International Airport (SJC) during the West Plan and the Southeast Plan. Southeast Plan air traffic routes are frequently implemented during winter months. When these procedures are in place, jets will fly over northern East Bay communities on arrival routes to both Oakland and San Francisco International Airport. As displayed by the flight track map, SFO aircraft arrival tracks intersect with OAK aircraft arrival tracks in the north Bay Area. To keep these aircraft safely separated, air traffic routes have been established by the FAA to maintain the SFO arrivals above the OAK arrivals.
