Aircraft noise from Moffett Federal Airfield, NASA Ames, and San Jose International is preempted by federal FAA rules. Sunnyvale cannot regulate overflight noise but offers a local complaint reporting channel.
Aircraft operations over Sunnyvale are governed by federal law, specifically the Federal Aviation Act, which preempts local noise ordinances for aircraft in flight. The city sits beneath departure and arrival paths for Moffett Federal Airfield (operated by NASA Ames Research Center and leased portions to Google), San Jose Mineta International Airport, and general aviation routes to Palo Alto and Reid-Hillview. Large tenants like Lockheed Martin Space on Mathilda conduct occasional rocket and aerospace test activity near Moffett. Residents in the Lakewood and Morse Park neighborhoods often log complaints with the Santa Clara County airport noise office and the NASA Ames community affairs line. The city maintains a local aircraft noise complaint page but cannot enforce altitude or flight path changes. Ground-based aircraft engine run-ups at Moffett are subject to base operating policies rather than city rules.
