Tomorrow afternoon Van Nuys Airport is holding a public meeting in Van Nuys, Calif., concerning the environmental impact report associated with the airport’s plan to draft an ordinance that would phase out aircraft that generate 77 dBA or more on takeoff. The seven-year phase-out would begin on January 1, with the 77-dBA limit taking effect on Jan. 12, 2016, with exemptions for some military, police, fire, search-and-rescue, medical emergency, maintenance-related and historic-aircraft operations. Van Nuys is one of the busiest general aviation airports in the world, averaging some 400,000 movements a year, and its 700 acres are home to more than 100 businesses. Owned by the city of Los Angeles, the airport says it contributes $1.3 billion to the Southern California economy.
