Ground Delay Program

A delay program, implemented at the FAA Command Center, based on established airport acceptance rates. Designed to control air traffic volume to airports where the projected traffic demand is expected to exceed the airport’s acceptance rate for a lengthy period of time. Flights that are destined to the affected airport are issued Expected Departure Clearance Times (EDCT) at their point of departure; flights that have been issued EDCTs are not permitted to depart until their Expected Departure Clearance Time.
