WA System Plan Chapter 8

Washington Aviation System Plan, July 1, 2009 Page 147 CHAPTER 8: CAPACITY ANALYSIS A capacity analysis was conducted in LATS to measure how well the existing facilities and components associated with Washington airports accommodate aviation activity in the state. In Phase I of LATS, existing airport capacity in Washington was first measured against current levels of aviation demand. Then in Phase II of the study, existing airport capacity in Washington was measured against forecast levels of aviation demand, allowing us to identify potential capacity constraints and/or shortfall across the state through 2030. Five types of airport capacity were examined as part of the LATS capacity analysis: • Airfield Capacity: the ability of an airport’s runway system to accommodate take-offs and landings without experiencing delays. • Commercial Airline Passengers: the ability of an airport terminal to accommodate airline passengers with adequate space for ticketing, security, etc. • Air Cargo: the ability of an airport to accommodate processing of air cargo tonnage using existing facilities. • Aircraft Storage and Parking: the ability of an airport to accommodate storage of based and transient aircraft in tie-downs and hangars. • Airspace System: the ability of available airspace to safely accommodate aircraft in transit between airports. A number of airports across Washington are expected to experience either airfield, passenger terminal, or aircraft storage capacity constraints by 2030. These airports are shown in Exhibit 7-1 and identified in the capacity discussions following.
