Jump to: navigation, search

The EDCT report of Airport Analysis provides counts of arrivals and departures with Expect Departure Clearance Time (EDCT) delays at selected airports. EDCTs instructing aircraft to remain at the departure airport until a specified time are issued when weather, congestion, or other problems en route or at the arrival airport will impede flights from arriving at the destination airport as originally planned. They are typically issued in conjunction with traffic management initiatives implemented by the FAA Command Center.

At least one Grouping option needs to be selected to generate an EDCT report.

For information about how to create an EDCT report, see the ASPM Airport Analysis Manual.

Field definitions are available in Definitions of Variables.
