AIRPORT NOISE COMPATIBILITY PROGRAM Louisville and Jefferson County FINDINGS AND RECOMMENDATIONS

1. AIRPORT NOISE COMPATIBILITY PROGRAM Louisville and Jefferson County FINDINGS AND RECOMMENDATIONS

2. ABATEMENT CROSSWALK • Air Traffic Control • Approach & Departure Procedures • Operator Procedures • Airport Policies and Regulations • Program Management • Structural measures • Control measures • Procedural measures • Management measures • Evaluative measures

3. STRUCTURAL MEASURES • offset path for approach to 17R, departure from 35L • extended approach fixes and departure turn points for higher maneuvering altitudes • optimized flight corridors following river and major highways • waypoints to guide traffic in corridors, rather than radar vectors • navaids as required to define waypoints • navigational standards for fleet • runway extension for higher north departure on 35L; displaced south arrival on 17R held pending cost/benefit analysis

4. CONTROL MEASURES • prefer* south flow, except as provided below • from 0930-1230, prefer* north flow • for operations north of the airfield, prefer* runway 17R with offset for arrivals, 35L with offset for departures • retain current operations south of the airfield (no runway preference*; diverge from 17R according to traffic & destination) • retain/enhance contraflow program • minimize exceptions to contraflow • * “prefer” means according to the same criteria used now for weather, runway conditions and traffic load, recognizing that peak operations typically require both runways if available

5. PROCEDURAL MEASURES • publish standardized arrival, departure procedures • provide for uniform descent at safe (3º) slope; discontinue current altitude exceptions • grant visual approach clearance only after aircraft pass final approach fixes • publish preferred noise abatement procedures in approach and departure plates • prefer uniform descent procedures for arrivals • prefer distant abatement procedures for departures • continue current run-up restrictions

6. MANAGEMENT MEASURES • establish airport noise office • community noise forum to succeed Study Group (same construct) • maintain Website and information centers • reinforce communications and liaison links with staff, carriers, controllers, government agencies, media, and public • equip noise office with hardware and software for effective monitoring and evaluation • develop real-time runway use decision aids, with common access for management, ATC, carriers, and community

7. EVALUATIVE MEASURES • establish flight track monitoring system • provide for sample noise monitoring • maintain fleet lists for • exceptions to noise abatement program (i.e. light aircraft) • navigational performance capability • develop and tabulate data sets for various metrics • conduct in-house noise modeling • document and evaluate emerging technologies and measures for potential application

8. ASSESSMENTS • airfield capacity & delay • air traffic control issues • aircraft operational and economic issues • cost analysis • financial feasibility • ...must be applied to entire package!

9. A “PUNCH LIST” • capacity and delay issues • chapter draft reviews • contraflow management program • cost/benefit assessments • approach procedures • displaced threshold analysis • updated airport economic impact • new technology documentation • revised fleet forecast • navigational capabilities list • data collection/metrics • runway extension update • runway use figures • scope issues, e.g. tech memos • revised UofL impact • workbook updates
