44 | UNDERSTANDING THE AIRPORT’S ROLE IN PERFORMANCE-BASED NAVIGATION Potential Contributions of the Airport to the Procedural Development8 This chapter describes where and how aircraft operators can contribute to the process of design-ing flight procedures. These suggestions are based on the responses of the broad range of stakeholders surveyed. The potential contributions of airport personnel are presented within the framework of FAA’s 5-phase process, although are applicable to any procedure development process. Phase 1: Preliminary Activities • Establish and maintain relationships with FAA and airline personnel involved in the design of PBN procedures. • Share known limitations of the current flight procedures and their impacts on the airport, aircraft operators, and local community. • Support specification of objectives and constraints for design of the procedures to address the limi- tations of the legacy procedures and airspace as well as other issues, including noise. • Support the characterization of the baseline operations of the airport and local airspace with analy- sis and information. • Identify noise-sensitive areas around the airport, specify allowable noise thresholds for those areas, and propose design features to satisfy the constraints. • Communicate the limitations of the legacy flight procedures, the design objectives, and the poten- tial impacts of the proposed procedures to the community and other stakeholders. • Understand the concerns of the stakeholders regarding the proposed design. • Translate concerns of the community and other stakeholders into design objectives and constraints for the procedures. • Communicate the concerns of the community and other stakeholders to the design team. • Translate their concerns into procedure design considerations. • Propose refinements to the objectives and constraints of procedure design to address the concerns of the community and other stakeholders. Phase 2: Development Work • Share airport data, information, and operating characteristics to support the design and simulation- based evaluation of the PBN procedures. This could include data such as preferred runway configu-

This could be as involved as working with an analyst to configure parameters for TARGETS, AEDT, and/or other software tools. • Evaluate noise and emissions analysis results generated by the procedure design team analysts to assess compatibility of the proposed procedures with the airport’s environmental requirements. For example, comparing generated noise contours against known noise-sensitive areas and thresholds, or conducting independent analysis of data to assess noise impacts. • Brief the community on the evolving design in scoping sessions or other outreach forms and obtain their feedback. • Propose design changes to satisfy the environmental requirements where potential issues have been identified. • Brief the community on the resulting design in scoping sessions or other outreach forums to educate them regarding the design objectives and constraints, design approach and tradeoffs, anticipated impacts on the airport, airline(s), FAA and other stakeholder(s), the community, and the environment. Phase 3: Operational Preparations • Conduct or support completing any final environmental review, community outreach or other activities in preparation for implementation. Phase 4: Implementation • Review published procedures to ensure they comply with the requirements of the airport operator, community, and other stakeholders. • Communicate identified or potential issues to the design team. Phase 5: Post-Implementation Monitoring and Evaluation • Conduct independent analysis of the impacts of the procedures, such as noise, throughput, or flight efficiency. • Evaluate noise and emissions analysis results to assess the compatibility of the implemented procedures with the airport’s environmental requirements and to assess their agreement with the impacts estimated in Phase 2: Development Work and the design objectives specified in Phase 1: Preliminary Activities.
