Runway Use Programs

• Alter preference for east runway

Limit runway preference to daytime only
Eliminate runway preference
Reverse runway preference

• Raise tailwind threshold for reversing flow to 10 knots

• No exceptions to contraflow, unless emergency

Flight Track Changes

• Set uniform departure criteria for turning

Altitude
Distance
Navigation markers
Geographic features

• Make west runway divergence 15°, not 20

• Apply divergence to all departures on west runway

Approach and Departure

• Route all arriving traffic into IFR approach corridor - no cancellations
• No VFR
• Noise-optimal SIDs/STARs

Navigation Technology

• Ground-based

markers
beacons
lasers
other

• Airborne

GPS/FMS (current vs milspec)
microwave

Airport Facilities

Referred to New Technologies Committee:

• “Hush houses”
• Counter-frequency generators

Airport Use Restrictions

• Conformance to noise compatibility program (NCP) by all aircraft

Airport Regulations

• Require NCP briefings for all tower personnel and pilots using SDF

Enhancing/Monitoring

• Show effect of full conformance to current NCP, compared to base case
• Noise monitoring
• Flight track monitoring

Screening Criteria

• Goals & objectives

Study goals
Study Group issues

• Reduces noise exposure

Minimize incompatibilities
Assess using noise model

• FAR Part 161

Impact on interstate commerce
Not discriminatory

• Consistent with FAA objectives

Aviation safety
Airspace management

• Feasible

Cost analysis
Monitorability
