NOISE ABATEMENT PROCEDURES

Early turn Takeoffs on runways 16L and 16R shall climb straight out 2.2 miles DME and attain a minimum 1800' MSL prior to turning. The VNY Noise Management Office notifies any aircraft owner identified as conducting operations contrary to the Van Nuys Airport Early Turn Policy and Procedure. The program uses the notification process to communicate to the operators the requirements of this airport noise abatement program and to assist the pilots to fly the established departure route and altitude. Quiet Departure program Jet airplane operators are to conduct south departures so that measured noise levels are below a pre-established departure criterion. The Noise Management Office (NMO) monitors jet departure noise and flight track data at various locations surrounding the airport. Jet aircraft departure operations that exceed a preset noise level at a specified noise monitor are notified of the incident. This program is used to monitor and modify takeoff aircraft operations and to assist pilots in utilizing the appropriate noise mitigation takeoff procedures. Program formally started in February of 1994. Call (818) 909-3571 for departure target noise levels for a specific airplane. Helicopter and Route Deviation Program The flight patterns for helicopters during ingress and egress operations at Van Nuys Airport specify recommended minimum altitudes of 1300 feet MSL upon leaving the airport boundary. Additionally there exist six distinct routes. The FAA has established a series of VNY flight routes that specify ingress and egress and altitude minimums in order to maximize the safety and efficiency of traffic control and to mitigate the noise impact to the adjacent communities. The Noise Management Office notifies helicopter owners of those ingress and egress operations that deviated from the established routes. The program uses the notification process to assist pilots to fly the established routes and altitude minimums and to minimize flight and noise impacts in local airport residential areas. The addition of a discrete FAA beacon code (1204) provides helicopter operators a separate frequency to request an approved route and altitude. Call (818) 909-3571 for a copy of the prescribed routes.

CONTINUOUS DESCENT ARRIVAL (CDA) - NONE

AIRPORT CURFEWS

The partial curfew applies to all Stage 2 fixed wing jet aircraft that generate a noise level equal to or above 74 decibels (per FAA Advisory Circular 36-3H) from departing the airport between 2200 and 0700 hours. Certain older and noisier model stage 3 jets are prohibited from departing the airport between 2300 and 0700. Newer Stage 3 jets are exempt from curfew times but should comply with the other VNY noise abatement programs. Helicopters, medical flights (Life Guard Operations with proper documentation), military or other government owned aircraft involved in law enforcement, emergency, fire or rescue operations are exempt at all time. Violators of the ordinance will pay civil penalties, which range from $750 for the first violation to $3500 for the third violation. For those with more than three violations, the operator will be banned from using the airport. "Touch and Go" operations are not permitted between the hours of 2200-0700 (local time) from June 21 through September 15; and between the hours of 2100-0700(local time) from September 16 through June 20.

Part 150 NCP The FAA issued a Record of Approval for the Van Nuys Airport FAR Part 150 Noise Compatibility Program effective October 16, 2009.  Approval included three of fourteen Noise Abatement elements, two of three Noise Mitigation elements, two of two Land Use Planning elements, and eight of sixteen Program Management elements. PART 161 STUDY Provided by the Airport 6/2005 The following are the proposed mitigation measures to be studied as part of VNY's Part 161 1. Incentives/Disincentives in Rental Rates: Establish a set of incentives and disincentives through differential rental rates to encourage the greater use of quieter aircraft and less use of noisier aircraft at VNY. This Proposed Restriction would establish rental rates for leases and tie downs correlated to the level of noise generated by the aircraft; 2. Incentives/Disincentives in Landing Fees: Establish a system of differential landing fees for aircraft using VNY with higher landing fees for noisier aircraft and lower landing fees for quieter aircraft; 3. Establish Fines for Violations of VNY Noise Abatement Policies: Establish a system of monetary penalties (fines) to be imposed on aircraft operators who violate noise abatement policies at VNY. This Proposed Restriction would make the voluntary VNY Fly Friendly program mandatory and establish penalties for violations of the program. This Proposed Restriction would enable the City of Los Angeles to implement the following penalties: $500 for the third (3rd) violation; $1,000 for the fourth (4th) violation; and $2,000 for the fifth (5th) and subsequent violations. Any operator who commits a 6th violation would be banned from using VNY; 4. Establish Maximum Daytime Noise Limits: Establish a maximum daytime noise limit for all aircraft operating at VNY of 77 dBA; 5. Establish a Limit on Stage 3 Jets: Establish a cap on the number of Stage 3 jets that may be based at VNY; 6. Expansion of the VNY Curfew: Amend the existing curfew ordinance to expand the hours of the current curfew to include all non-emergency jets and non-emergency helicopters as aircraft that would come under the provisions of the curfew during the hours of 10:00 p.m. to 7:00 a.m.; and 7. Establish a Cap or Phase-Out of Helicopters: Establish a cap on the number of, or a phase-out of helicopters from VNY. Due to the large number of Proposed Restrictions to be analyzed, the estimated timeframe for completion and submittal of the VNY Part 161 applications to the FAA is from three to five years. The consulting firm of Harris Miller Miller & Hanson, Inc (HMMH) of Burlington, MA was selected to direct the study.

NOISE LEVEL LIMITS

Van Nuys Airport implemented maximum noise levels for aircraft operations effective April 15, 2010, per City of Los Angeles Ordinance No. 181106, which amended Ordinance No. 155,727 (VNY Noise Abatement and Curfew Regulation).  This ordinance provides a timetable restricting the operation of noisier aircraft by Takeoff Maximum A-Weighted Sound Levels, per FAA Advisory Circular 36-3. Nighttime curfew from 2200-0700 (local time) based on noise level limit. Any fixed wing aircraft which produces 74 dBA or greater on take-off per AC36-3H may not depart during the curfew hours. Stage 3 aircraft (newer or modified jet-engine aircraft) are not affected by the curfew until 11:00 p.m. (local time). Violators of the ordinance will pay civil penalties which range from $750 for the first violation to $3500 for the third violation and for those with more than three violations; the operator will be ban from using airport. The curfew does not apply to helicopters, emergency flights or military aircraft. Landings are not restricted.

STAGE 2 RESTRICTIONS

Aircraft <75,000 lbs Van Nuys Airport implemented the Non-Addition Rule on June 10,2000, per City of Los Angeles Ordinance No. 173,215, which amended Ordinance No. 155,727 (VNY Noise Abatement and Curfew Regulation). The Non-Addition Rule prohibites any additional fixed wing aircraft with noise levels exceeding 77 dBA from being based at Van Nuys Airport, subject to certain exceptions. This Ordinance does not apply to Stage 3 aircraft.

Stage 2 airplanes >75,000 lbs are prohibited from operating at airports within the 48 contiguous states.

STAGE 2 PHASEOUT

U.S. Stage 2 Phase out complete as of 12/31/1999 (CFR Part 91.801). Stage 2 airplanes >75,000 lbs are prohibited from operating at airports within the 48 contiguous states.

Per Resolution No. 20736 (aircraft >75,000 lbs) The existing based exempt or "grandfathered" fleet of Stage 2 based aircraft will be allowed to continue to operate at VNY. For the six years after adoption of the new regulation (or until December 31, 2005), Stage 2 based aircraft permanently being removed from VNY can be replaced with replacement aircraft that do not exceed 85 dBA on takeoff. After January 1, 2006 only Stage 3 or Stage 2 aircraft with 77 dBA or lower on departure will be allowed as replacement aircraft.

STAGE 3 RESTRICTIONS

See Airport Curfews.

COMMENTS

Van Nuys Airport is one facility in the Los Angeles World Airports (LAWA) transportation system. Each LAWA airport has well established noise abatement regulations and policies developed by the City of Los Angeles and adapted to each community served by the facility. Over the last twenty years Van Nuys Airport management has implemented a series of Noise Abatement programs to regulate aircraft operations conducted at Van Nuys Airport and Noise mitigation programs to reduce the noise impact on the surrounding communities.
