A. SUMMARY
Counts of aircraft noise complaints by community and by month. The Aircraft Noise Abatement Office collects this data via the Complaint Hotline, Online Complaint Form, emails, letters and telephone calls to our office. This information is collected and published in a monthly report which is presented at the SFO Airport Community Roundtable meetings. It is used to understand community's aircraft noise concerns, to collaborate with stakeholders in an effort to reduce and manage aircraft noise.

Counts of airline operations that incur noise exceeding threshold by airline and by month. The Aircraft Noise Abatement Office collects this data using an Airport Noise and Operations Management System. It is collected using remote noise monitor sites in the communities surrounding SFO. This data is collected to monitor and grade airlines' performance as part of SFO's Fly Quiet Program.

Please see Runway Usage dataset for current information.

The preferred departing runways from 1:00 a.m. to 6:00 a.m. are 10L/R, 01L/R or 28L/R with an immediate right-turn when safety, weather and traffic permits. This reduces aircraft noise in residential communities surrounding the airport as over water-departure procedures directs aircraft over the bay. This dataset provides the amount of aircraft late night departures by runways. The percent of departures are calculated based on the month's total departures.

A. SUMMARY
This dataset shows the amount of nighttime engine high power run-ups from 10:00 p.m. to 7:00 a.m. by air carrier operations using jet and regional jet aircraft. Power run-up activities are conducted at designated locations on the airfield, furthest from residential communities, and monitored by SFO to manage nighttime noise. A power run-up is a procedure used to test an aircraft engine or aircraft system after maintenance or repair is performed. The aircraft engines' throttle settings can range from ground idle to high power and the length of the operational checks may vary in duration. These checks are required to ensure normal operating standards are met, prior to returning the aircraft to service.

B. HOW THE DATASET IS CREATED
Details of each power run-up are logged into the Airport Operations System. It serves to help quantify, analyze, and report on power run-up activities in support of programs to reduce aircraft noise in communities surrounding SFO.

C. UPDATE PROCESS
Data is available starting in January 2005 and will be updated monthly.

D. HOW TO USE THIS DATASET
This information is the data source used in producing the Nighttime Power Run-ups section (page 4) of the Airport Director’s Reports. These reports are presented at the SFO Airport Community Roundtable Meetings and available online at https://noise.flysfo.com/reports/?category=airport-directors-report
