GDPs in Support of SWAP Initial Concepts CDM A&D Meeting. January 24, 2001
Background • There are Two Goals in the Use of GDPs in Support of SWAP • Reduce Airspace Demand • Reduce Arrival Rates to Avoid Airport Gridlock CDM A&D Meeting
Airspace Demand Reduction • When Severe Weather requires Flight Re-Routes, the overall airspace capacity in the region around the weather is reduced • Flight Demand on the Airspace must be Reduced • This only affects flights near the weather CDM A&D Meeting
Airport Demand Reduction • However, Severe Weather that is Close to a Major Terminal Area can Severely Limit the Departure Flow from the Airport • Since this can lead to Gridlock, the Entire Flow to the Airport must be Slowed • This affects all flights destined for one of the affected Terminal Areas CDM A&D Meeting
Solutions • Potential Solutions have been described by Rick Oisen • Including Various Uses of FSM or SMT • Focus Here on Specific Uses of FSM and Airport GDPs • What Can We Do to Improve GDPs in Support of SWAP With the Tools that we Have Today? CDM A&D Meeting
Approach – Previous • GDP/SWAP Decision Guidance Flowchart • Historical Airspace Demand Including Arrival/Departure Airports • Between Centers • Through Arcs • Through Sectors • Through Common FCAs • Suggested Airport GDPs with Rates • Which Airports & What Rates • Between Centers • Through Common FCAs CDM A&D Meeting
ATCSCC Personnel Input • Cannot Readily Determine % Reduction of Airspace Capacity • Majority of SRV WX Events Become An Airport Event • Need to Determine Departure Rate to Set Arrival Rate • Known Factors Are Route Status / MIT CDM A&D Meeting
Approach – Revised • Historical Departure Demand • From Major Terminal Areas • Broken-Down by Departure Route • Predicte Departure Delays, based on • Departure Fix/Route Closures • Miles-in-Trail Restrictions on Departure Fixes/Routes • Allow Determination of GDP Rate Based on Predicted Departure Delays CDM A&D Meeting
Schedule • Spring 2001 • Quick Development of Paper Based Guidance • In the Future / Summer ‘02 • Guidance can be Added to Existing or New Tools CDM A&D Meeting
