ASPM Key Advisories: GDP & GS Report
The GDP & GS Report of ASPM Advisories provides summary reports of Ground Delay Programs and Ground Stops (GDP and GS), with drill-down capability to individual advisories.
For information about how to create a GDP & GS Report, see the Advisories Manual.
Field definitions are available in ASPM Advisories: Definitions of Variables.
The GDP & GS Report displays the following fields:
- GDP. The number of Ground Delay Programs affecting arrivals for the specified facility(ies) and date(s). GDPs require aircraft to be held on the ground at the departure airport due to congestion or other conditions at the destination airport or e route. Flights that are destined to the affected airport are issued Expected Departure Clearance Times (EDCT) and not permitted to depart until their Expected Departure Clearance Time. ECDTs are calculated in such a way as to meter the rate that traffic arrives at the affected airport; ensuring that demand is equal to acceptance.
- GS. The number of Ground Stops affecting arrivals for the specified facility(ies) and date(s). Ground Stops are initiated when the projected traffic demand is expected to exceed the airport's acceptance rate for a short period of time, to temporarily stop traffic allowing for the implementation of a longer-term solution, such as a Ground Delay Program or when the affected airport's acceptance rate has been reduced to zero. Flights that are destined to the affected airport are held at their departure pointfor the duration of the Ground Stop.
