The San Diego International Airport is conveniently located to many San Diego residents and businesses. Even though the location is convenient it does create some inherent challenges for those who live and work near the Airport.
SAN along with the airlines, the FAA and Air Traffic Control (ATC) strive to balance the needs of the community with those of the passengers of SAN. Even though we do not dictate the flight path (that’s the responsibility of the FAA and ATC) or fly the planes (that’s the airlines), it is our job to act as an intermediary between all parties fostering transparency in airport operations over the communities surrounding the airport.
The following pages are meant to help explain Airport Noise Mitigation's role in these tasks and what we are doing to help reduce noise in the community.
“The Curfew” is a part of the Airport Use Regulations, formally adopted as SDCRAA Code 9.40, Airport Use Regulations. In the simplest of terms, “The Curfew” is the Time of Day Restrictions that limits nighttime aircraft departures.
The following text has been excerpted from the Airport Use Regulations. If you have any questions or concerns regarding these regulations, please contact Airport Noise Mitigation at (619) 400-2789, Monday through Friday 8:00 a.m. - 5:00 p.m. During all other times, please call (619) 400-2799.
Additionally, a multiplier may be added to reflect the multiple number of violations during the previous compliance period. After the 3rd (or more) offense, the operating privileges of any operator may be terminated, or limited, on such terms and conditions, and for such period of time, as the Authority Board determines is appropriate.

Will aircraft continue to become quieter?
The current production of civilian aircraft is markedly quieter than the older technology aircraft. Dramatic reductions in engine noise have occurred since the early 1980s. However, the reduction in noise with each new generation of engine is not as dramatic as previous generations. Small evolutionary changes may be occurring, but the technological noise reduction achieved through higher engine bypass ratios has a limit, and that limit is being approached. This information does not imply that reductions achieved will not be maintained, only that the continued improvements may be less dramatic. A new Boeing 787 has approximately one-tenth the noise “signature” on departure as a Boeing 727-200, yet it carries more than twice the number of passengers. Because aircraft have operating lives of 20 or more years, it takes decades for airline fleets to catch up to the latest and quietest technology. Absent any compelling incentive or regulatory requirements to retire older aircraft, airlines naturally expect to extend the usefulness of their capital investments for as long as possible.
FAR Part 150
14 Code of Federal Regulations (CFR) Part 150, Airport Noise Compatibility Planning, was issued by the Federal Aviation Administration (FAA) as a final rule in January 1985. 14 CFR Part 150 sets forth the methodology and procedures to be followed when preparing aircraft noise exposure maps and developing airport /airport environs land use compatibility programs.
14 CFR Part 150 studies typically consist of two primary components: (1) the Noise Exposure Map (NEM) report which contains detailed information regarding existing and 5-year future airport/aircraft noise exposure patterns, and (2) the Noise Compatibility Program (NCP) report which includes descriptions and an evaluation of noise abatement and noise mitigation options/programs applicable to an airport.
The Airport Authority is in the process of updating the Part 150 including new NEMs and an update to the NCP. As part of this effort, a Citizen Advisory Committee (CAC) and Technical Advisory Committee (TAC) have been established to review information and provide input on the study update.
Information from these meetings is provided below.

The next CAC and TAC meetings will be held on July 19, 2018. The TAC will meet from 10:00 a.m. – Noon and the CAC will meet from 2:00 – 4:00 p.m. Meetings will be held at the Airport Noise Offices in Liberty Station, 2722 Truxtun Road, San Diego 92106.
The Quarterly Noise Report details the noise activities at the San Diego International Airport. Information includes statistical summaries, aircraft noise measurements, information on airport operations, noise complaint statistics, enforcement actions, reports on the residential sound insulation program and information about the Airport Noise Advisory Committee.
A variance is required by the California Department of Transportation when there are areas surrounding the San Diego International Airport that are impacted by more than 65 dBs of noise. Therefore, in order to maintain operations the San Diego International Airport must have conditions in place in order to reduce noise impacts to those in areas above 65 dBs of noise.
