About Washington Dulles International Airport
Overview
Washington Dulles International Airport serves as a critical international gateway for the Washington, D.C. metropolitan area. Located in Dulles, Virginia, the airport handles significant commercial and international air traffic, situated at an elevation of 312 feet mean sea level. Its strategic location provides essential air transportation infrastructure for the national capital region.
Flying Conditions
The airport's multi-runway configuration offers significant operational flexibility across different wind conditions. With four runways ranging from 9,400 to 11,501 feet in length, pilots can expect adaptable approach and departure options. The airport's elevation and geographic position suggest potential for variable wind patterns and seasonal meteorological transitions.
Notable Features
Dulles features three concrete runways (01L/19R, 01C/19C, 01R/19L) and one concrete/grooved runway (12/30), providing robust operational capabilities. The airport's coordinate location at 38.944500, -77.455803 places it in a region with complex terrain and potential airspace interactions characteristic of the mid-Atlantic coastal zone. Runway lengths exceeding 9,400 feet accommodate a wide range of aircraft types and operational requirements.
Approach Considerations
Pilots should anticipate multiple runway options based on prevailing wind conditions, with primary runways 01C/19C and 01R/19L offering the longest operational surfaces at 11,500 feet. The diverse runway configuration allows for flexible approach and departure strategies, particularly during challenging meteorological conditions. Standard instrument approach procedures will vary based on specific runway and wind vector interactions.
