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.

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 power runup is a procedure used to test an aircraft engine or aircraft system after maintenance is completed. This is done to ensure safe and normal operating standards prior to returning aircraft to service. High power runups performed by aircraft operators are monitored to manage noise.
