Helicopter noise is an issue all over Los Angeles County, and several local congress members sponsored a bill last summer that would instruct the Federal Aviation Administration to start regulating it. One of them, Rep. Adam Schiff, D-Pasadena, also represents La Cañada, Altadena and Montrose-La Crescenta.
