Overview

• Weather delays• ATCSCC Overview• A Day in the NAS• Possible Future Products



Weather Delays

• About 70% of delays in the National Airspace System (NAS) consistently attributed to weather

• Leading causes are:– Thunderstorms

• En route and terminal– Winds– Ceiling and Visibility– Snow– Hurricanes



ATCSCC Overview

• Responsible for balancing air traffic demand with system capacity across the NAS



ATCSCC Overview

• At any one time, there may be over 5000 flights in the NAS



ATCSCC Overview

• National System Strategy Team (NSST)– Traffic Management Focal Point– Responsible for developing the Operations Plan – Coordination responsibilities

• National, regional, and international• Tactical Customer Advocate

– Works matters specific to airline-defined critical flights• Weather Unit

– Provides current and forecasted weather information



A Day in the NAS• Start with a big picture look



A Day in the NAS• Continue with leading airport forecasts

A Day in the NAS• The Strategic Planning process

• 0-6 hours into the future• Updated every 2 hours beginning at 0515 local

• Strategic Telecons facilitated by ATCSCC• Collaborative Decision Making (CDM) participants

• FAA facilities• Aviation industry

• CDM is a philosophy on how to conduct business between the various components of aviation transportation, both government and industry. Two central principles are:

• Information exchange and data sharing • Tools and procedures in place



A Day in the NAS• Look at current weather radar with air traffic



A Day in the NAS• Airport tactical responses (0-1 hour) with Integrated Terminal

Weather System (ITWS)



A Day in the NAS• Regional tactical responses (0-2 hour) with Corridor

Integrated Weather System (CIWS)



A Day in the NAS• Look at forecasted conditions with the Collaborative Convective

Forecast Product (CCFP)



CCFP Characteristics• Coverage

– Sparse: 25-49%– Medium: 50-74%– Solid: 75-100%

• Echo Tops (feet)– 25 – 31K– 31 – 37K– > 37K

• Confidence– Low: Gray– High: Blue

• Snapshot– 2, 4, 6 hour



A Day in the NAS

• Identify demand/capacity imbalances



A Day in the NAS

• The ATCSCC devises a suitable plan with other Air Traffic facilities and system users for addressing constraints. Through coordination with affected air traffic facilities and users, an operations plan is developed to ensure the safe and orderly flow of air traffic around impacted areas. As the weather changes, the plan can be revised and, if necessary, new routings or restrictions are issued.

A Day in the NAS

• Types of Traffic Management Initiatives• Reroutes

• Avoid constraints •Miles in Trail (MIT)

• # of miles required between aircraft

• Airborne Holding• Dependent upon airspace

• Sequencing• Specified interval between aircraft

• Ground Delay Program (GDP)• Aircraft delayed at departure airport to manage demand and capacity at arrival airport

• Airspace Flow Program (AFP)• Aircraft delayed due to en route constraint

• Ground Stops• Aircraft remain on the ground; usually reactive



• Localized Aviation MOS Program (LAMP) Thunderstorm Probability

• Under consideration to augment CCFP at extended times

Possible Future Products



• Integration of CIWS into Traffic Management Decision Support Tools


Decision support tools




• Consolidated Storm Prediction for Aviation (CoSPA)
