San Jose FAQ
Why does SJC sometimes do engine runs at night?
Safety-of-flight maintenance for early-morning departures occasionally requires after-hours runups approved by the airport duty manager. SJC logs these events and posts them in monthly noise reports so neighbors can correlate complaints to specific permitted activity.
Can the city stop late-night runups at Reid-Hillview?
No directly. Reid-Hillview is operated by Santa Clara County under FAA Part 150 with grant assurance commitments to remain open. The city can only ask the county and operators to comply with voluntary nighttime restrictions and based-tenant rules.
How loud is a jet engine runup?
Commercial jet engine runups can exceed 100 dBA at 100 feet, dropping with distance, blast fences, and orientation. Designated runup pads aim to direct exhaust away from residential receivers, but communities directly downwind still report substantial noise during permitted windows.
Sunnyvale FAQ
Are SJC engine run-up restrictions mandatory?
FAA Part 150 voluntary procedures are not directly enforceable as fines. However airport operators can suspend ground-handling privileges and terminate leases for repeat violators. Most operators comply due to lease consequences.
Where do I report a late-night run-up at SJC?
Call the SJC noise hotline or file an online complaint via flysanjose.com. The airport tracks run-up events and reports patterns to the FAA, operators, and the San Jose airport commission.
