DCA Airport Noise MWAA WG Dec 15, 2016
BACKGROUND FAA Next Gen noise Analyzed on macro level Data below 3K Ft under estimated community level impacts Primary focus has been on departure procedures 1 part of overall problem We have system problem Each WG member focused on their community Need systems approach to address noise consequences Present consensus WG approach to help fix system 2
6 Point Plan 1. Noise Assessment/Footprints 2. Procedures 3. Fly Quiet Program 4. Permanent Advisory Group 5. RSIP 6. Dulles Matters 3
Comprehensive Plan #1 Noise Footprints Airspace use trends since 2006 have influenced DCA traffic 1. Determine current noise environment and effect of recent trends (operations, fleet mix, schedule, flight path variances etc.) that led to current condition. 2. Comparison of previous and current noise environment as determined through evaluation of historical noise monitor data with validation of accuracy of noise monitor system. 3. Validity of FAA and/or MWAA/DCA noise analysis supporting environmental documentation related to changes. 4. Comparison of noise level and population impacts modeled by FAA accepted noise modeling methods before and after implementation of procedures. 4
2004 Part 150 Study INM Airport Contours 5
Noise Contours Part 150 Study 2004 1. Part 150 Noise Assessment 2004 Part 150 study 2009 update Noise contours around DCA only Noise models generated based on many assumptions. Learning curve steepest with something that has not been done before Many FAA assumptions not holding true. Actual flight tracks post Next gen change must be analyzed against assumed flight tracks in pre-change model Once discrepancies solutions can be identified. 6

New Noise Foot Prints Needed 8
Comprehensive Plan #1 Noise Footprints Noise monitor impact data before/after change to procedures (LAZIR) Voids in noise monitor locations Departure/arrival trends between 10 PM and 7 AM since 2006 Complaint observations associated with noise impact and flight activity Verify accuracy of noise monitors and data collected by DCA ANOMs Evaluate if supplemental noise monitoring is appropriate Noise exposure impact related to controllable factors (time, aircraft type, runway use) Verification of modeled baselines using monitored data and historic data Noise exposure maps that enable comparison of impacts and populations for various metrics and time periods of departure routes Grid map of DNL change comparing departure routes Future 2026 noise exposure map and population impacts based on updated forecast and fleet mix projections and future Next Gen phases Noise abatement program measures and improvements for consideration Identify Next Gen related factors that are increasing community impacts and annoyance (dispersion reductions and related frequency increases) 9
Comprehensive Plan #2 Flight Procedures 1. Keep aircraft over Potomac C/L greatest extent possible N & S. Parkland and other unpopulated areas Beyond American Legion Bridge/past David Taylor facility (N) Further south past Piscataway park (S) 2. Add or move departure and IAF waypoints away from communities and further west/sw and south as possible 3. Increase departure procedure altitudes; set and eliminate variability in departure altitudes at transition turn to min of 5K or higher as safety permits 4. Disperse departure flight paths to reduce concentrated flight tracks 5. Review Rwy 1 and 19 approach procedures to ID changes that can be implemented to reduce noise exposure 6. Implement Continuous Descent Approaches for each runway 10
Comprehensive Plan #3 Fly Quiet Program FQ programs in place at airports across US Airlines operate as quietly as possible. Reduce single event and total noise levels Mandate and implement noise abatement and FQ procedures NADP 1 or NADP 2 or developed for DCA FQ manual to air carriers, ATC and published on MWAA site Training and educational materials Fly Quiet Program Rating Recognize airlines that reduce noise footprint. Quietest fleet contest 11
Comprehensive Plan #3 Fly Quiet Program FQ rating based on airline categories and scores Carriers with more than 1,000 annual operations Carriers with less than 1,000 annual operations at DCA Fly Quiet Top Rating for regional airline; at least 360 annual operations Criterion Fleet Noise Quality Noise Exceedance Rating Noise Abatement Rating Departure and Approach Quality Rating Noise Complaints Keeps focus on importance of aircraft noise reduction 24x7 Assesses operator FQ program adherence and performance Help influential air carriers to upgrade fleet Keep public informed and current with noise mitigation programs 12

Comprehensive Plan #4 Permanent Advisory Group Noise issues never go away Keep as focal issue Part 150 group and report 12 years past Can t let drift back to business as usual. Needs to focus on ops not politics Key role in FQ program. Reps as community liaison and educators 14
Residential Sound Insulation Program RSIP exists across US Reduce impact of aircraft noise inside homes, apartment and condos, schools within 65 DNL noise contours. Sound insulation may include new attic insulation; acoustically rated exterior doors, storm doors and windows Funded by AIP and PFC Goal is to achieve quieter environment and better quality of life within homes/schools in highest impacted areas affected by aircraft noise. 15
Support Dulles Matters Plan 1. Bolster VA, MD and DC efforts 2. Prevent expansion of DCA 1250 NM perimeter and allowing future additional beyond perimeter flights. 3. Bi-Partisan support from VA, MD and DC 4. Balance flights between IAD and DCA 5. Develop Long Term Strategic Plan for DCA and IAD to include economic growth and objectives, passenger needs, flight safety, air carrier requirements and noise mitigation. 16
Next Steps Consensus from WG Submit as WG Resolution Refine/develop details for WG plan Subcommittees? Finalize in 4-6 months? Include on agenda for all future meetings 17
