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.

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
