Transportation authorities around the globe are working to keep air traffic moving on time
in a safely Metered flexible environment. Traffic Management Advisor is a robust decision
support tool that enables controllers to keep pace with growing airspace demands.
Why Choose CSC for Your
Advanced ATM Solutions?
CSCs Traffic Management Advisor
(TMA) will enable a regional/national
integrated metering trajectory flow
capability that will significantly
streamline arrivals and departures from
OEP airports, reduce delays, and
increase airport capacity. ITS services
was a natural outgrowth of CSC’s
fundamental
Since 1996, CSC has been developing
and maintaining the CTAS TMA for the
FAA. TMA is a system designed to
optimize arrival air traffic flow to the
runway threshold. Its goal is to develop a
coordinated arrival sequence and
schedule, display this plan to Traffic
Management Coordinators (TMCs) in
the Air Route Traffic Control Center
(ARTCC) and Terminal Radar Approach
Control (TRACON), and provide
optional advisories to sector controllers
that enable them to implement the plan.

Realtime Arrival Schedules: CTAS TMA is
a Decision Support Tool (DST) for airport
arrival and departure management. The tool
calculates arrival schedules in real time based
on three factors:
• Flight Plan and track data received from
the Host Computer System
• Winds aloft data received from National
Weather Service (NWS)
• Information entered by the TMCs and
controllers
Maximize Enroute Operations: TMA uses
computational techniques to transform the
information available in the existing National
Airspace System (NAS) into optimized
traffic flow schedules for airport traffic
managers. For arrivals, it produces an arrival
plan meeting flow requirements for the
adapted airport.
Tools that delivers results: The tool
achieves this by generating a schedule that is
free of conflict at runway and meter fixes.
TMA graphically depicts fix/arc crossing
times of arrival aircraft. It does this by
making continuous predictions of aircraft
Estimated Time of Arrivals (ETAs).
Scheduling algorithms use the ETAs to
compute arrival schedules that include
Scheduled Times of Arrival (STAs) for each
aircraft to specific scheduling points such as
Runway Threshold, Final Approach Fix
(FAF), Meter Fix/Meter Fix Arc, Outer
Meter Arc, and Outer Outer Arc. The TMCs
use separation strategies to produce spatial
and time-based metering, such as aircraft
sequencing, miles-in-trail, and STAs for
aircraft at their meter fix and points that lie
on the Center TRACON boundary.

Supports Departure Metering between
Sectors and Centers: An En Route
Departure Capability (EDC) function has
been added by CSC to support departure
metering to points on the boundaries
between sectors or centers. Users are able to
optimize streams of aircraft leaving their
facility and schedule departures from
internal airports to merge with other traffic.
As with arrival TMA, users are able to
specify scheduling constraints and display
time ordered schedules and geographic
views of position data. EDC is currently
being deployed to all FAA centers.
CSC’s CTAS TMA software provides two
main display views: a Timeline Graphical
User Interface (TGUI) and a geographic
Planview Graphical User Interface (PGUI).
These views give the TMCs insight into
traffic flow in the ARTCC area of interest.
In addition, these views enable the TMCs to
interpret the traffic flow situation and make
strategic and tactical planning decisions to
manage the flow. TMCs make inputs
through these GUIs to alter traffic flow and
provide advisories to the enroute air traffic
controllers regarding TMC changes. ETA
and STA timelines are produced and
displayed by the TGUI, which places the
metered aircraft in a time-sequential spatial
order.
Leverage CSC’s Experience: CTAS TMA
Build 2, developed under an evolutionary
spiral approach paradigm, is as of March
2007 deployed to all 20 ARTCC’s in the
United States. Spiral development has
allowed for a building block approach,
incrementally developing and deploying
system functionality and incrementally
providing support products and services.
Beginning with the National Aeronautical
and Space Administration (NASA)/Ames
Research Center TMA concept development
prototype, CSC developed more than
380,000 additional lines of code for Spiral 1
that provided failure recovery capabilities,
system monitor and control functionality, a
redeveloped object-oriented GUI, and the
Host ATM Data Distribution System.
Spiral 2 development added data recording and
playback capabilities, internal departures, meter
fix arc, and irregular-shaped TRACON
functionality. Spiral 3, with adjacent center data
feed functionality included in the initial release,
is still on-going with new releases.
In addition to software enhancements, CSC
develops TMA adaptation data sets and has
completed the national deployment of TMA.
TMA deployment includes the main TMA
system at the center and remote GUIs at
adjacent centers, TRACONs, and towers.
Innovation and Thought Leadership Enables
the FAA Achieve its Mission: CSC continues
to develop and maintain the Spiral 3 software
baseline with recent additions
to the TMA system that include:
Use of EDC for Departure Scheduling
• Interface to STARS
• Adjacent Center Metering
• Multiple TRACON Support
• Collaborative Arrival Planner
• Dynamic Routing around Special Use
Airspaces
