ATCSCC GoalsBalance air traffic demand with the capacity of

the National Air Space (NAS), focusing on Safety and Efficiency

But… We have a Problem…~ 70% of delays in the National Airspace System (NAS) are attributed to weather which results in Aviation Industry loses in excess of $20,000,000,000 each year.

How do we mitigate weather impacts to the NAS?

The AWC NAMs provide Integrated Decision Support Services (IDSS) to the FAA in support of the NAS

Weather Ready Nation AWC NAMs are trained in Meteorology and Traffic Flow Management Partnered with FAA, CWSUs, WFOs, Airline Mets and NCEP Centers Developing innovative methods/products to deliver weather impact information

Most IDSS is: Terminal (Airport) Impacts

Arrival/Departure Gates Weather at Airport Ground Stop (GS) Ground Delay Program (GDP)

Enroute (Cruising) Impacts Route blockage

Traffic Flow Management Portalhttp://testbed.aviationweather.gov/page/public?name=TFM%20Portal

Ground Stop (GS) Holds aircraft at departure airport Can be immediate/unplanned Used when Weather will directly impact an Airport for ~ 1 hours Emergency situation at airport Airplanes need to land…they don’t have to take off

RED = In Air

YELLOW = Ground Stopped

GREEN = Airborne Soon

Ground Delay Program (GDP)

Used when Weather will directly impact an Airport for > 2 hours Control Air Traffic to Airports where demand > capacity Each flight gets a specific departure time Each flight gets a delay

Air Flow Program (AFP) Control volume through an en route volume of airspace Usually one-way, i.e. East Coast volume to Florida (spring break) Assigned time to cross an line rather than arrival time at an airport

Military areas offer very limited corridors with little variance for

lateral adjustment of route

Where is the bigger “aviation” impact?

JFKEWR

NY Airspace is most congested in the NAS
