Welcome to the WSDOT Aviation Economic Impact Calculator. This tool is designed to assist users in estimating an airport’s change in regional economic impacts based on potential changes in activity at the airport. The calculations in this tool are high-level estimates designed to give a sense of magnitude of economic impacts, but are not to be taken as specific projections. The tool uses averages and typical ranges to provide a reasonable estimate of impacts based on the types of changes entered, which should not be assumed to be precise calculations.
The base data used in the Calculator comes from the Airport Information System (AIS) database, which consists of airport activity information self-reported by airport managers. It is important to keep in mind that inaccuracies or out of date information in the AIS may result in estimates that are inconsistent with the current state of the airport.
