John Wayne Airport Orange County

Santa Ana, California, United States

Noise Abatement Information - Last update 04/01/2016

HIGH

  Overview

John Wayne Airport (SNA) is one of the busiest and most noise sensitive airports in the United States. The Airport is located in the center of Orange County, California with residential areas in close proximity. To mitigate potential noise impacts from aircraft operations and to enhance compatibility with surrounding communities, the Airport maintains some of the most stringent noise rules in the United States. The General Aviation Noise Ordinance (GANO) has been adopted by the County of Orange to regulate the hours of operation and the maximum permitted noise levels associated with general aviation operations.
This information has been prepared to introduce you to the GANO and to encourage the operation of your aircraft in the quietest manner possible consistent with safety. The Airport recognizes that pilot sensitivity is a key component of a successful noise abatement program, and your continued cooperation is greatly appreciated.
