Commercial Air Carrier & Cargo Carrier
Quarterly Average Noise Limits
Noise-based limitations on aircraft operating at John Wayne Airport (JWA) are defined in the John Wayne Airport Phase 2 Commercial Airline Access Plan and Regulation (Access Plan), and in the Settlement Agreement between the County of Orange, the City of Newport Beach and two community groups.
Two noise-based classes have been established for commercial passenger and cargo operations at JWA: Class A and Class E. Aircraft in these Classes: (i) operate at gross takeoff weights not greater than those defined in the Access Plan; and (ii) generate single event noise levels, averaged over the noise compliance period (one quarter), that are no greater than the values presented below.
Class A Noise Limits*
Class E Noise Limits*
* Single Event Noise Equivalent Level (SENEL) limits were revised: October 6, 2015
Typically, Class A aircraft serve long- and medium-haul markets (more than 1,000 miles). This type of operation usually requires more fuel to reach its destination and, as a result, can require greater thrust on departure. The combination of heavy fuel loads and greater thrust correlate to the higher noise levels established for this class of operation.
Class E departures generally serve short-haul markets (less than 1,000 miles). Class E aircraft typically carry less fuel and as a result, are lighter and quieter than the Class A operations.
Some aircraft can operate in both Class A and Class E. For example, a Boeing 737 flying from Orange County to Northern California could qualify as Class E, where the same aircraft traveling from Orange County to the East Coast would likely fall into the Class A category.
