Aircraft Noise Advisory Committee
The San Diego County Regional Airport Authority (SDCRAA) recognizes that neighborhoods surrounding San Diego International Airport are affected by noise from aircraft operations. An Aircraft Noise Advisory Committee (ANAC) (Committee), consisting of individuals from various organizations, residential areas, and professional associations, was formed in 1981 under the San Diego Unified Port District, the previous operator of San Diego International Airport (SDIA). The Aircraft Noise Advisory Committee is formally adopted as Airport Authority Policy 9.20.
The Committee, composed of no more than 18 voting members, provides a forum for collaborative discussion of aircraft noise issues and other related matters. Voting members may include representatives of the following entities, agencies, industries, or interested groups:
Community Representatives within 65 Decibel Contour:
- 1. Downtown Community Planning Council
- 2. Greater Golden Hill Planning Committee
- 3. Midway/Pacific Highway Community Planning Group

Curfew Violation Review Panel
The Airport Authority Board recognizes that neighborhoods surrounding San Diego International Airport are affected by noise from aircraft operations. San Diego County Regional Airport Authority Code 9.40, Airport Use Regulations at San Diego International Airport, contains certain Time of Day operational restrictions (The Curfew). The Code includes a mechanism for levying administrative penalties against operators who violate the Airport Use Regulations.
A Curfew Violation Review Panel (CVRP) evaluates and enforces compliance with the Airport Use Regulations, Time of Day Restrictions (The Curfew), and makes recommendations for the disposition of these incidents.
The Committee is composed of Airport Authority employees and consists of three members (or his/her designated representatives):
- Vice President, Operations
- Vice President, Development
- Vice President, Administration
“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 Restriction 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) 400-2660, Monday through Friday 8:00 a.m. - 5:00 p.m.
Time of Day Restrictions
- Arrivals / All Aircraft – There are no noise-related Time of Day Restrictions on arriving aircraft. Arrivals are permitted 24-hours a day.
- Engine Run-Ups – No person shall perform an engine run-up at a power setting above idle power between 11:30 p.m. and 6:30 a.m. (2330-0630L) local time, unless necessary to complete an Emergency/Mercy flight.
- Nighttime Departures / All Aircraft– No person shall operate any aircraft scheduled or unscheduled on departure from the airport between the hours of 11:30 p.m. and 6:30 a.m. (2330-0630L) local time unless they meet the exceptions criteria. This applies to all operations regardless of Category, Class, Type, or Noise Certification Level of the aircraft.
- Stage 1 and Stage 2 Aircraft (including rotorcraft) – No person shall operate any aircraft on departure, or perform an engine run-up at a power setting above idle power, from the airport between the hours of 10:00 p.m. and 7:00 a.m. (2200-0700L) local time.
- Emergency and Mercy Flights - Time of Day Restrictions shall not be applicable to any aircraft operation which is conducted in an Emergency or Mercy Flight Status. These flights shall be authorized in advance by the senior airport official on duty (typically the Airside Operations Duty Manager – who can be contacted during curfew hours through the Tower Controller by radio or by calling 619-400-2710). The operator must provide a written report with full details on the nature of such operation to the Aircraft Noise Mitigation office, no later than three (3) days after the occurrence. Please click here to access the Emergency/Mercy Flight Exemption form.
- Engine Run-Ups – Engine Run-ups shall not be applicable when the run-up is necessary to allow an aircraft engaged in an emergency or mercy flight to comply with safety, legal, or regulatory obligations or requirements prior to commencing operation.
All operators are subject to a fine for violation of these policies. The Curfew Violation Review Panel (CVRP) evaluates and enforces compliance with Airport Use Regulations, Time of Day Restrictions (curfew) and makes recommendations for the disposition of these incidents.
The compliance period runs from January 1 through June 30 and July 1 through December 31 each year.
- 1st offense per calendar 6-month compliance period: $2,000
- 2nd offense per calendar 6-month compliance period: $6,000
- 3rd offense per calendar 6-month compliance period: $10,000
Additionally, a multiplier will be added to reflect the 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.
The purpose of the San Diego International Airport’s (SDIA) Fly Quiet Program is to encourage commercial operators to operate as quietly as possible in the San Diego area by acknowledging those operators that attempt to follow the noise abatement goals of the airport. The program creates a participatory atmosphere of the operators working with the airport and community to actively reduce noise by grading an operator’s performance and by making the scores available to the public. The Fly Quiet Program offers a dynamic venue for reviewing noise abatement initiatives by praising and publicizing active participation rather than a system that admonishes violations from essentially voluntary procedures.
Currently, the Fly Quiet Program scores commercial operators on the three most commonly voiced concerns from residents surrounding the airport, curfew violations, early turns and fleet noise quality. The higher the score, the quieter the operator is flying in and out of SDIA.
Fleet Noise Quality:
The Fleet (or type of aircraft an operator uses) Noise Quality score evaluates the noise contribution of each operator’s fleet as it actually operates at SDIA. Operators generally own a variety of aircraft types and schedule them according to both operational and marketing considerations. The Fly Quiet Program assigns a higher rating or grade to operators operating quieter, new generation aircraft, while operators operating older, louder technology aircraft would rate lower. The goal of this measurement is to fairly compare operators – not just by the fleet they own, but by the frequency that they schedule and fly particular aircraft into SDIA.
The method used here bases an operator’s Fleet Noise Quality Rating on established by the FAA’s 14 CFR Part 36 noise certification data. For each aircraft type, Part 36 specifies allowable noise levels at three measurement locations: approach, departure, and sideline. Part 36 allowable noise limits increase with weight, so that larger aircraft, serving more passengers, are not penalized as compared to smaller types. The rating method for the Fleet Noise Quality rating totals the difference between each aircraft’s certified noise levels at all three measuring points and the Stage 3 standard for that weight and number of engines. Aircraft with the greatest number of decibels below Stage 3 threshold are rated the best. Similar to and consistent with Part 36, the Fleet Noise Quality Rating allows for higher noise levels for larger aircraft. It is important to credit larger aircraft serving more passengers because they offer more air service in fewer flights and less total noise than multiple operations in smaller aircraft types.
Eliminating loud aircraft noise events is a long-standing goal of the Airport, as a result, the Airport has established an element that identifies the loudest aircraft operating at SDIA. The arrival and departure exceedances are captured at Daytime, Evening, and Nighttime levels.
The locations of the Noise Monitoring Terminals (NMT’s) where exceedances are captured are as followed:
- NMT #2 - Approximately 3.5-nautical miles (6.5km) along the departure path east of the airport.
- NMT #14 - Approximately 3.5-nautical miles (6.5km) along the departure path west of the airport, for straight-out departures.
- NMT #24 - Approximately 3.5-nautical miles (6.5km) along the departure corridor northwest of the airport, for right turn departures.
The Noise Exceedance Score for each operator is determined by adding the different categories of noise exceedances together and adjusting them to the number of operations to generate a score of up to ten (10) points. The current threshold settings are 90 dB for daytime departures (7:00 a.m. to 7:00 p.m.), 85 dB in the evening hours (7:00 p.m. to 10:00 p.m.), and 80 dB during nighttime hours (10:00 p.m. to 7:00 a.m.).
SDIA has an existing curfew violations system in place as part of the Airport Use Regulations that may result in a monetary fine if an operator violates the curfew. An operator that does not log any curfew violations during the time period is automatically assigned a score of ten (10) points. If the Airport’s Curfew Violation Review Panel determines that a flight violated curfew and will be penalized, the score will be adjusted by subtracting two (2) points. If the Airport’s Curfew Violation Review Panel determines that a flight violated curfew and will not be penalized, the score will be adjusted by subtracting one (1) additional point.

The purpose of the San Diego International Airport’s (SDIA) Residential Noise Monitoring Program is to provide members of the community the opportunity to have a short-term portable noise monitoring conducted at their home or place of business, where non-compatible uses occur, e.g., sleeping or learning. In addition to 23 permanent noise monitors, located throughout the communities, SDIA provides homeowners the opportunity to request a temporary noise monitor at their residence. Upon written agreement, and provided your residence meets the technical requirements, SDIA will set up a temporary noise monitor for a period of five days (Monday – Friday) and complete a detailed technical report, upon conclusion. The final report will provide aircraft and community noise levels, a data comparison to a nearby permanent monitor, and other general information about noise measurements and Airport operations.
How to Request Portable Monitoring
San Diego residents may request a portable test by submitting your Portable Noise Monitoring Application online. Once the Application is received by SDIA, staff will contact the homeowner with a questionnaire to qualify the residence for noise testing. One major requirement is that the test site is a fenced and private property, in order to reduce the risk of equipment theft.
Upon the initial site qualification, SDIA staff will send the homeowner a Test Agreement, via Docusign, which the homeowner must sign for. The Agreement clause include the use, distribution and availability of results, physical security of the equipment, utility power usage, and risk acceptance, amongst others.
Test Appointments and Reporting
When the Application and a signed Portable Test Agreement are received, Noise Office staff will contact the homeowner to schedule two appointments: the initial setup and the retrieval of the test equipment. The test period will be Monday through Friday (5 days) and will run continuously. During the equipment set-up appointment, a technician will arrive on Monday morning. Consequently, upon completion of the test, the equipment will be collected on a Friday afternoon. All equipment set-up and break-down activities will be conducted only during normal (8 am – 5 pm) business hours. Following the completion of testing, Aircraft Noise staff will generate a report within 30 days of the testing.
