FAA Data

Printer-friendly version

The Federal Aviation Administration (FAA) has agreed to provide the City of Brisbane with data detailing the aircraft that depart from San Francisco International Airport and that fly through a circle that the FAA has created for analytical and operational purposes, located over the City of Brisbane, as shown in the left-hand image. The circle has a diameter of 1 nautical mile.  The FAA’s objective is to avoid having aircraft penetrate the circle if possible given safety and other operational constraints. 

Over time, it is the objective of the FAA to have fewer aircraft entering the circle, and fewer flying at low altitudes over Brisbane, between 10pm and 7am.  The data delivered by the FAA do not explain why there might be a low or high number of aircraft on a given day.  For example, a plane may penetrate the circle for reasons related to a safe takeoff.  At some times, airport runways may be closed due to fog or to other circumstances.  When the national air space is stressed due to weather or other conditions, this may impact how many planes take off from SFO and at what times and altitudes.  It should be noted that the data captured in the spreadsheets reflect only those flights which are SFO departures, and do not take into account aircraft penetrating the circle that may have originated from Oakland International Airport or be destined for that airport or any other.  All this being said, it is the City of Brisbane’s understanding that it is the FAA’s objective to work to address the concerns of Brisbane residents about noise.  This data is provided to the City by the FAA to assist in understanding how well this objective is being achieved over time.  Thus, it is expected by Brisbane that the FAA will update this data regularly.
