Facilities and aircraft

Quillayute Airport covers an area of 739 acres (299 ha). For the 12-month period ending December 31, 2006, the airport had 6,700 aircraft operations: 97% general aviation and 3% military.[1]

The airport has two concrete runways, each one close to 5,000 feet (1,500 m) long. Runway 12/30 is closed (the north–south runway). Runway 4/22 is open with a displaced threshold of 1,089 feet (332 m). In the Master Planning effort currently underway, it is the intent, in the long-term plan, to remove the displacement on runway 4/22 in the future, and reopen runway 12/30 at a shortened length.
