Air Traffic Roles and Responsibilities • As aviation technology advances, the FAA is putting in place satellite based procedures to increase safety and efficiency • These procedures allow airplanes to safely arrive and depart an airport in all weather conditions • Procedures aren’t designed to reduce or move noise but as we improve safety and efficiency, we work to try and reduce the impacts of noise by trying to put them over water or industrial areas

SAFETY AND EFFICIENCY • How do procedures increase Safety? • Decreased controller workload and complexity • Decreased pilot errors • Increased pilot and controller situational awareness • Enhanced obstacle and terrain avoidance • Better access to runways in all weather conditions • Decreased radio transmissions, reduced buffers between routes, and fewer traffic conflicts
• How do procedures improve efficiency? Reductions in fuel burn and emissions Federal Aviation Administration

What is LAZIR? • LAZIR is a standard instrument departure (SID) • Development started in 2011 to use advanced navigation to allow aircraft to fly more over the water and to stay clear of restricted airspace

What’s Next • Nine new DCA SIDs for Runway 01 overlay the existing path of LAZIR – Three were implemented on April 30, 2015 – Six remaining will be published June 25, 2015 – Currently, 19 participating carriers are being assigned these procedures when DCA is in a north flow
• The National 5 SID, a conventional procedure, is available to non-participating carriers or upon pilot request • FAA will continue to work with the airport authority as they work with local stakeholders to explore additional ways to improve safety and efficiency and reduce any noise impacts

FAA Noise Management Areas • Scientific and technical basis to better understand aircraft noise – Research program centered around noise generation, propagation, annoyance, sleep disturbance, health effects, speech interference and modeling
• Maturation of aircraft technology and procedures to reduce noise – Continuous Lower Energy, Emissions, and Noise (CLEEN) program
• Certification Standards for Aircraft (14 CFR Part) – Part 36: noise certification and ICAO Annex 16 volume I – Part 91: aircraft phase-outs
• Operating Restrictions – Part 161: airport noise and access restrictions
• Voluntary Programs – Part 150: airport noise compatibility planning (including insulation) – Airport-Airline-Air Traffic programs to reduce manage aircraft noise.

DNL & Modeling • Day-Night Average Sound Level (DNL) 65 decibels (dB) – DNL was adopted due to provisions of the Aviation Safety and Noise Abatement Act (ASNA) of 1979. FAA adopted the DNL metric and the 65 dB land use compatibility guideline. Last reviewed in 1992. – Value FAA uses to define significant noise and land uses are deemed compatible, unless community and airport adopt a lower local standard. – Current work ongoing to review whether DNL as metric or level needs to be changed.
• Modeling Noise – Modeling captures full range of the aircraft fleet, airport runway configurations and usage, flight routes and operations. – FAA models are developed in accordance with international standards, validated through various controlled measurement studies involving detailed flight performance, weather and noise data. – Monitoring only provides snapshots in time at a specific location with specific aircraft operations. Monitoring data is highly dependent on day to day operational conditions, locations and cannot be used to calibrate noise models.
