Aviation plans & studies

WSDOT Aviation has been involved in various studies to help better understand the benefits of the Washington state aviation system.

WSDOT-managed airport planning

We have developed Airport Layout Plans (ALP) and Narrative Reports for nine of the 15 State-Managed Airports located throughout Washington state: WSDOT-managed airport planning

Aviation Economic Impact Study

Airport Investment Study and Airport Investment Study Solutions

The Airport Investment Study found that the state’s 134 public-use airports will need $3.6 billion in projects during the next 20 years. WSDOT’s Airport Aid Program provides an average of $1.1 million in state airport grants per year. During the 20-year study period, the state grant program is forecasted to average $1.4 million per year. WSDOT estimates an average of $12 million per year is needed to meet the state’s portion of the overall $3.6 billion in project needs. The study concluded in June of 2015.

Airport Centric Energy Systems

Airports operate within a dynamic, burgeoning aviation landscape that demands constant modifications and upgrades to facilities and operations. Although airports have historically faced various challenges, aviation appears to be at the precipice of a significant paradigm shift that will transform how airports interface with fuel and energy. Alternative fuel types, such as Sustainable Aviation Fuel (SAF) and hydrogen, are increasingly used or considered by various operators. Many electric aircraft are being developed to be used as part of Advanced Air Mobility (AAM) and traditional aviation uses. Also, the growing electric vehicle (EV) market strains airports as they face a rapid escalation in charging loads.

Advanced Air Mobility Aircraft Plan 

The Advanced Air Mobility (AAM) Aircraft Plan was developed in response to Engrossed Substitute House Bill (ESHB) 1125, Section 213(3), which directed WSDOT to evaluate the feasibility, infrastructure needs, regulatory pathways, and economic implications of incorporating AAM into Washington’s transportation network. This report serves as a comprehensive guide to positioning Washington as a leader in AAM, leveraging its existing aerospace industry, multimodal infrastructure, and policy frameworks.

Electric Aircraft Feasibility Study

The state legislature tasked WSDOT Aviation Division to form the Electric Aircraft Working Group (EAWG) in 2018 to explore electric aircraft service across the state.

Washington Electric Airport Feasibility Study

A University of Washington study developed methods to estimate plausible future energy and power demands for electric aircraft operations at regional airports to determine whether the electric grid near two regional airports — Paine Field and Grant County International Airport — have the capacity to serve the potential energy (MWh) and peak power (MW) needs of electric aircraft operations over the next one to two decades.

Washington Statewide Aviation Sustainability Plan

The WSDOT Statewide Aviation Sustainability Plan is a comprehensive initiative aimed at making Washington’s aviation sector more environmentally friendly, economically viable, and socially responsible. Developed in collaboration with airports across the state, the plan provides a structured approach for integrating sustainability into airport operations. It focuses on key areas such as reducing environmental impact, improving energy efficiency, enhancing community engagement, and ensuring long-term financial stability.

The plan outlines practical steps for airports of all sizes to develop and implement sustainability strategies. These include adopting clean energy solutions, reducing emissions, conserving natural resources, and improving operational efficiency. By offering tailored guidance, funding opportunities, and best practices, WSDOT supports airports in aligning with state and federal sustainability goals. Ultimately, this effort aims to create a more resilient and sustainable aviation system that benefits travelers, businesses, and communities across Washington.

Slow down on ice and snow.

It's easier to skid or lose control traveling at higher speeds. Give yourself more time to stop.

Carry chains, practice installing them.

Winter conditions could mean chains are required on your route. Practice putting them on your vehicle ahead of time.

Pack your winter car kit.

Carry extra supplies like warm clothing, ice scraper and brush, jumper cables and other emergency items.
