The updates for the IASP and the AEIA will run concurrently and will both occur in three phases, following industry-accepted approaches, specifically the guidance provided in Federal Aviation Administration Advisory Circular 150/5070-7, The Airport System Planning Process.

During Phase 1, the study team will establish a PAC and initiate public consultation. System goals and performance measures will be established to identify information to be requested during the inventory data collection. Aviation issues and trends will be assessed at the local, regional, and state levels to identify how each might impact the system or individual airports in the future. Airports will be analyzed and categorized by their role in the overall system, considering the services and facilities each provides. Aviation forecasts will be developed to identify future systemwide demand and, based on a comparison of current and forecasted demand to airports’ services and facilities, the adequacy of the system will be analyzed. Data collection for both the IASP and the AEIA will be conducted jointly. Upon completion of the initial data collection effort, initial estimates of economic impact will be developed.

During Phase 2,the majority of the remainder of the IASP and AEIA tasks will be conducted. For the IASP, system requirements will be identified to ensure Idaho’s airports are able to meet existing and projected demand. A series of alternative development options will be evaluated, taking into consideration environmental issues and requirements. Based on these analyses, a recommended airport system will be identified to provide the best flight plan for developing Idaho’s airport system. Additionally, there will be an analysis of intermodal connectivity and access needs for Idaho’s airports, as well as an analysis of current regulations concluding with a series of policy and program recommendations. This phase will also include a recommendation on airport category changes for those Idaho airports included in the Federal Aviation Administration’s (FAA’s) National Plan of Integrated Airport Systems (NPIAS).

During Phase 3, a final implementation plan will be developed, identifying system priorities and providing justification for the plan’s recommendations and future actions. This phase will come to a conclusion with the development of a final technical report, comprised of all previously generated chapters.

Additionally, spin-off or multiplier impacts will be estimated and combined with Phase 1’s initial impact estimates to provide an estimate of the total annual economic impacts of aviation in Idaho. The tax impacts associated with the state’s airports will be assessed, as will the value-added business and qualitative benefits. A timeline depicting changes in aviation’s economic impact in Idaho will be developed.
