GDPs in Support of SWAP Initial Concepts CDM A&D Meeting. January 24, 2001 24 Jan 01 CDM A&D Meeting

Background z. There are Two Goals in the Use of GDPs in Support of SWAP y. Reduce Airspace Demand y. Reduce Arrival Rates to Avoid Airport Gridlock 24 Jan 01 CDM A&D Meeting 2

Airspace Demand Reduction z. When Severe Weather requires Flight Re. Routes, the overall airspace capacity in the region around the weather is reduced y. Flight Demand on the Airspace must be Reduced y. This only affects flights near the weather 24 Jan 01 CDM A&D Meeting 3

Airport Demand Reduction z. However, Severe Weather that is Close to a Major Terminal Area can Severely Limit the Departure Flow from the Airport y. Since this can lead to Gridlock, the Entire Flow to the Airport must be Slowed y. This affects all flights destined for one of the affected Terminal Areas 24 Jan 01 CDM A&D Meeting 4

Solutions z. Potential Solutions have been described by Rick Oisen y. Including Various Uses of FSM or SMT z. Focus Here on Specific Uses of FSM and Airport GDPs y. What Can We Do to Improve GDPs in Support of SWAP With the Tools that we Have Today? 24 Jan 01 CDM A&D Meeting 5

Approach – Previous z GDP/SWAP Decision Guidance Flowchart z Historical Airspace Demand Including Arrival/Departure Airports x. Between Centers x. Through Arcs x. Through Sectors x. Through Common FCAs z Suggested Airport GDPs with Rates x. Which Airports & What Rates • Between Centers • Through Common FCAs 24 Jan 01 CDM A&D Meeting 6

Sample Reference Table for ZOB to ZNY Flows 24 Jan 01 CDM A&D Meeting 7

ATCSCC Personnel Input z. Cannot Readily Determine % Reduction of Airspace Capacity z. Majority of SRV WX Events Become An Airport Event z. Need to Determine Departure Rate to Set Arrival Rate z. Known Factors Are Route Status / MIT 24 Jan 01 CDM A&D Meeting 8

Approach – Revised z Historical Departure Demand y. From Major Terminal Areas y. Broken-Down by Departure Route z Predicte Departure Delays, based on y. Departure Fix/Route Closures y. Miles-in-Trail Restrictions on Departure Fixes/Routes z Allow Determination of GDP Rate Based on Predicted Departure Delays 24 Jan 01 CDM A&D Meeting 9

Schedule z. Spring 2001 y. Quick Development of Paper Based Guidance z. In the Future / Summer ‘ 02 y. Guidance can be Added to Existing or New Tools 24 Jan 01 CDM A&D Meeting 13
