Washington Air Route Traffic Control Center (ZDC) is an Area Control Center operated by the Federal Aviation Administration and located at Lawson Rd SE, Leesburg, Virginia, United States. The primary responsibility of ZDC is the separation of airplane flights and the expedited sequencing of arrivals and departures along STARs (Standard Terminal Arrival Routes) and SIDs (Standard Instrument Departures) for the Washington-Baltimore Metropolitan Area, the New York Metropolitan Area, and Philadelphia among many other areas.

Basic breakdown of sectors
editZDC is divided into 8 areas, numbered 1 through 8, that make up 46 sectors. They are mainly broken down into low altitude, intermediate, high altitude and Super High Altitude sectors. There are 18 low sectors, 14 high sectors, 5 super high sectors and 4 various other type sectors, including 1 high/low altitude sector and 3 intermediate altitude sectors.
AREA 1
editSuper-high sectors
edit- 72 Shenandoah SHD 127.925 MHz/269.375 MHz
- 07 Wahoo WAH 121.925 MHz/346.375 MHz
During periods of traffic saturation in the Shenandoah Sector, ZDC will split the Shenandoah sector into two sectors, making Wahoo a second Super High Sector over the Roanoke and Lynchburg, Virginia areas. Shenandoah normally overlaps the Tech High and Gordonsville High Sectors above FL330. When traffic demand is high, Wahoo is activated to overlap the Gordonsville High Sector above FL330 covering J37 and J75 from GVE VOR south while Shenandoah will overlap Tech High Sector above FL 330 and cover traffic on J48 from CSN VOR south, J22 from MOL VOR south and J53 south of ASBUR intersection near LWB VOR.
