Here is the updated program for the March 6 AIAA Workshop on ATM and Free



³ATM in the 21st Century: Where Does Free Flight fit in?²

Wednesday, March 6, 1996 8:00 AM to 4:30 PM
Loew¹s L¹Enfant Plaza Hotel
L¹Enfant Promenade, SW Washington, DC

Lunch provided, included in $10 registration fee.

The Air Transportation Systems Technical Committee of the
American Institute of Aeronautics and Astronauts will host a
1-day workshop on the interaction between Air Traffic Management
and the new Free Flight concept for Air Traffic Control.

Speakers from the airlines, FAA, NATCA, NASA, and other
interested organizations will trade ideas on how the future ATM
system should be shaped. For more information, please contact
Emily Davies at (703) 264-7533, e-mail

Bill Cotton, United Air Lines: "AIAA's Contribution to Free

The Technical Committee needs to consider its work program in
light of the future Air Traffic Management environment in which
free flight is the operating concept.  AIAA needs to provide a
unique contribution to this major developmental effort to be
relevant during the next ten years.

Lane Speck, FAA: "Free Flight"

What is it?  Where is it?  Where is it going?  How is it going
to get there?   What's in it for you?  How you can help.

John Pyburn, MITRE/CAASD: "The National Route Program
Feasibility Analysis: First Steps Toward Free-flight"

Over the past several years, an initiative known as the National
Route Program has allowed greater flexibility for airspace users
to select their route of flight.  At intervals over this time,
the criteria for eligibility for this style of flying have
become less and less restrictive.  Using computer modeling, we
have analyzed the feasibility of this program for the FAA.  It
should be seen as the first steps towards free-flight.

Dallas Denery,  NASA Ames Research Center: " Status of ATM
Research at the Ames Research Center")

New concepts for air traffic management in the terminal area and
on the surface, referred to as the Center Tracon Automation
Systems and Surface Movement Advisor, are under development at
NASA Ames in cooperative programs with the FAA.  The
technologies emerging from these programs provide near term
operational benefits and provide the key building blocks for
achieving efficient gate-to-gate operations while allowing
operator flexibility in routing and scheduling in high density
airspace.  In this paper results of recent field tests at Denver
and Dallas Ft. Worth will be reviewed.  Plans for SMA tests at
Atlanta will also be discussed.  Initial work at Ames in
developing automation aids for user preferred routing in the
enroute airspace with a smooth transition to the terminal area
will be covered in a separate presentation.

Heinz Erzberger, NASA Ames Research Center:  "Conflict Detection
and Resolution in the Presence of Trajectory Prediction-Errors"

Because automated conflict detection and resolution is based on
imperfect prediction and control of trajectories, a trade-off
exists between early resolution at lower maneuver costs, but
significant false alarm costs, and late resolution with higher
maneuver costs but negligible false alarm costs.  The known
error characteristics of trajectory prediction and control can
be used to guide the design of a resolution strategy that
minimizes the average cost of resolution.  Such a resolution
strategy is being incorporated in the design of an integrated
set of Center automation tools that support user preferred
routing (UPR) enroute and a smooth transition to efficient
control of arrival traffic in high density airspace.  Field-test
proven CTAS technology, including its real time trajectory
synthesis and conflict detection algorithms, provide the
foundation for the design.  Field tests of UPR functions will
begin at the Denver Center in the summer of 1996.  NASA's
data-link and GPS equipped TSRV Boeing 757 will also participate
in the test.

John Scardina, Integrated Product Team Lead, FAA and Frank
Willingham, Program Manager, MITRE/CAASD: "Maximizing Delivery
of User Benefits Through Integrated ATM Functionality."

This paper describes an evolutionary approach to achieve maximum
flexibility and efficiency for airspace users through fully
integrated Air Traffic Management system functionality. The
approach provides for early benefits via quick fielding of
initial increments which require only minimal integration. Then,
achieving higher levels of integration with subsequent
deployments via inter-domain, functional integration packages of
decision support services. This approach assumes deployment of
the physical infrastructure as currently planned for the en
route, terminal and tower domains.

Air Delta Air Lines Experience with a Flight Planning System to
Support Greater Flexibility"

Steve Brown,  AOPA/RTCA Task Force 3: "General Aviation's
Priorities for Free Flight"

Karl Grundmann, NATCA: "NATCA's Perspective on Free Flight"

What the union  sees in looking at Free Flight:  advantages,
disadvantages, trouble spots, issues, problems, and ways to
resolve them.

John Ball, Lockheed Martin: "Associate Technology and Its
Support of the Free Flight Concept."

Associate technology is a military based technology developed
under several ARPA contracts to provide decision and information
support to pilots.  Lockheed Martin sees this technology as a
critical piece to the implementation of the Free Flight concept
as it has been envisioned. I will give a brief discription of
how the system pieces fit together and discuss how this
technology provides user support and forms a network of
cooporating associates.

Jim Dieudonne, MITRE/CAASD: " Early Free Flight Evaluations --
Some Ups, Some Downs"

This discussion will center around early observations of the
"Free Flight Concept" based on analysis of current "unstructured
route operations", simulations and laboratory "experiments", and
field evaluations at the FAA's Kansas City Enroute Control
Center.  Some of these "early lessons learned" should help us
focus future activities.
