Sea-Tac/Boeing Field Airspace Study Newsletter May 1982

You have been included on our distribution list for the Airspace Study Newsletter either because of your membership in an organization which is aviation-related or because of your interest in aviation planning in the Puget Sound region. The Port of Seattle and King County are looking at the use of airspace around Sea-Tac International Airport (Sea-Tac) and its neighboring airport, King County International Airport (Boeing Field). Key study questions are: where are there overlapping aircraft traffic patterns which are also called airspace interactions, how often do airspace inter- actions occur and what are their impacts on aircraft trip time and the flow of aircraft traffic to and from Sea-Tac and Boeing Field? As the respective operators of Sea-Tac and Boeing Field, the Port of Seattle and King County are interested in providing airport facilities and services to airport users without creating undue congestion or delays. If existing or poten- tial congestion or delays are identified, measures· to lessen them are considered whenever possible. Airspace interac- tions between Sea-Tac and Boeing Field are a source of con- gestion and delays. Numerous Air Traffic Control facilities and procedures have been established to minimize these inter- actions. However, under certain weather conditions, over- lapping traffic patterns severely restrict the number of aircraft that can land and take off at Sea-Tac and Boeing Field, thereby creating delays. And as demands increase for use at Sea-Tac and Boeing Field, so do delays. What's happening now? How 1s the general public involved? What next? We have…
