Riverside, CA Noise Ordinances: Aircraft Noise (2026)

190 states flatly that no aircraft using the airport shall be operated, on the ground or in flight, in a manner that causes unnecessary noise. The section then lists specific noise-abatement procedures pilots must follow under visual flight rules unless doing so would be unsafe or air traffic control directs otherwise: Runway 9 departures must climb to 1,500 feet MSL before the first turn, while Runway 27 departures must turn right ten degrees at the runway's departure end to follow the river before climbing straight ahead to 1,500 MSL; missed approaches under VFR cannot descend below 1,200 MSL; the VFR approach to Runway 9 must stay well north of the housing area; standard pattern altitude is 1,800 MSL for conventional aircraft and 2,300 MSL for jets; aircraft must not descend below the Runway 27 visual approach slope indicator on final approach; twin-engine single-engine-departure practice should be minimized; jet aircraft must comply with Federal Air Regulation Part 36 and use a rolling takeoff consistent with safety; missed-approach and post-takeoff throttle settings should be kept to a minimum consistent with safety; and pilots must avoid Ramona High School on Magnolia Avenue.

08, including established left-hand traffic patterns (right-hand for Runway 16) and turn restrictions after takeoff, all aimed at routing airport traffic to minimize noise impact on surrounding residential areas near the field.
