RECOMMENDED NOISE MITIGATION PACKAGE

The following list details the recommended noise mitigation package for ASA. The main

change for ASA is adopting Runway 35 as the preferred and calm-wind runway.

Noise Abatement Procedures

• Establish Runway 35 as the preferential/calm-wind runway.

• Establish an additional departure procedure for Runway 35 departures,

which would allow a 90° right turn at 900' AGL.

• Change the altitude limit on left turns when departing Runway 35, which

would allow turns at 900' AGL rather than the existing 1200' AGL.

• Investigate the potential to allow a back-course approach to Runway 35 and

encourage the FAA to publish this procedure.

Land Use Program

• No Recommendation at this time.

Implementation Program

• Establish a continuing education program for pilots and tenants that includes:

o Pilot education committee

o NBAA and AOPA noise abatement training, which includes use of

helicopter flight patterns

o Low-level approaches

o Prop controls

• Replace existing on-airport noise abatement informational signs with larger

and clearer signs. The new signs should depict noise sensitive land use

areas and appropriate arrival and departure paths and procedures. Eliminate

all unnecessary signs from the field.

• Establish an airport noise monitoring committee that meets quarterly to

evaluate pilot compliance with established noise abatement procedures. The

committee should be comprised of pilots, tenants, community members, and

the ODA.

• Install Distance Measuring Equipment (DME/localizer) or Instrument Landing

System (ILS) for Runway 35. According to the DECIBEL Committee and

ODA either a DME or an ILS will be required before the FAA will allow

Runway 35 to be used as the calm wind runway.

• Upgrade the existing Runway 17 DME. According to the DECIBEL

Committee and ODA, an upgrade is required prior to instituting a back-course

Runway 35 approach.
