Airport Information System

The Airport Information System is an online program that provides the public with information about Washington's air transportation system.

Each airport in the state is able to update their information online and print reports. We use the information to measure aviation system performance over time and communicate improvement needs to decision makers. Airport sponsors are encouraged to log in, review and update their existing data at any time during the year as information changes. However as a condition for grant eligibility, airports are required to acknowledge their review and update by December 31 of the preceding calendar year. We create a benchmark of the data for each year.

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.
