Page 11 of 34 herein represent those remaining after multiple rounds of screening. Screening criteria included regulatory review (is this consistent with current federal, state, and local regulations), will it negatively impact safety, effectiveness, and cost (is it cost-effective?). Recommendations from each strategic area are described in detail in the following sections. Screening of the recommendations included input from the appropriate stakeholder groups to ensue acceptability to those ultimately responsible for implementation. As an example, flight procedures under consideration were reviewed with FAA air traffic control (ATC). Acceptance by ATC would be required as ATC is ultimately responsible for directing aircraft in flight and the overall management of the airspace. Recommendations that conflicted with ATC’s mandate would ultimately not be used, therefore, these were rejected from the final recommendations. Flight Operations and Procedures Flight procedures and operational practices make up the majority of the recommendations identified by the project team. A specific focus was placed on training operations as this class of operation was identified as a primary source of community noise impacts and subsequent concerns. The ultimate goal of the operational procedures is to reduce noise-exposure for airport-adjacent and nearby communities. In general, these strategies focus on: • Routing aircraft away from residential areas when possible • Increasing altitudes when overflying noise-sensitive/residential areas • Reducing nighttime operations Operations, regulatory requirements, and noise impacts vary by aircraft category. General recommendations were developed as well as recommendations based on specific aircraft categories (single-engine piston, multi-engine and turboprops, jets, and helicopters). Most operations and community concerns were attributed to flight-training operations, most of which involve single-engine piston aircraft. 43
