7. Observation Decision support track generally:
Did not emphasize long-term, future concepts in decision support tools
Did emphasize near to mid-term (needed) evolutionary concepts and capabilities
27 June 2003

8. Results
Trajectory Prediction Uncertainty: What is it? How to reduce? How to live with it in decision support tools?
Quality and standardization of input data remains a key issue in improving accuracy of predictions for decision support tools (DSTs) and simulations , e.g.:
Controller intent
Pilot intent
Take-off weight
Aircraft performance data (intellectual property and liability issues are significant vis-a vis access)
27 June 2003

9. Results
Trajectory Prediction: some solutions proposed to address uncertainty
“Closed loop solutions” implemented as active advisories to reduce intent errors
“Common trajectory prediction services” for multiple DSTs and domains
Application of Kalman Filter approach to dealing with wind error in cruise phase of flight
Need for coordinated research to set future direction reinforced
27 June 2003

10. Results
Automation Capability/Weather Information Integration to help human decision makers deal with weather situations
Concepts presented for utilization of current and forecast weather information in decision support tools:
Better enable controllers to assist pilots with weather avoidance
Deal with weather-related traffic flow situations
Enhance departure management
Initial steps in getting away from “fair weather tools”
More generally, integration of individually-developed decision support capabilities to realize “end-to-end” solutions, e.g
Automated dissemination of TFM initiatives, conflict detection/resolution consideration those initiatives and other conflicts, data link delivery of resultant clearances)
27 June 2003

11. Results
Decision making under uncertainty is a reality and will continue to be so; must develop ways to deal with it
Focus of most ATM research has been on reducing uncertainty at the data input level
Communication and expression of uncertainty (how, why and to whom) likely to be an increasingly important issue for all categories of service providers, users and pilots
Automation capabilities that support decision makers must also account for uncertainty (e.g. in weather forecasts, demand, capacity)
27 June 2003

12. Results
Better Traffic Flow Management decision making likely will require simultaneous application of multiple strategies
Research has generally focused on single answer solutions (rerouting, ground delay, miles-in-trail)
Increased attention to looking at the cumulative impact of multiple, possible strategies
Need to ensure that individual domain-level solutions/capabilities (e.g. departure management, arrival management, en route integrated impact assessment) will integrate together in coherent concept
27 June 2003

13. Results Conflict Detection/Resolution
Framework proposed for quantifying conflict resolution operational acceptance based on intended use
Key conclusion: if trying to resolve conflicts out to 20 minutes, need to use a separation criteria (in excess of 5 miles) based on level of resolution performance is needed operationally
Framework proposed for investigating conformance monitoring by posing it as a Fault Detection problem; possible use in assessing alternative conformance monitoring approaches
27 June 2003

14. Results (concluded)
ATM Infrastructure: what might the future look like?
Architecture concept postulated for implementing advanced autonomous aircraft concept of operations
Centralized data repository and security (SWIM)
Centralized decision support on ground
Cost-effective aircraft decision support capabilities
Strong dependence on data link
27 June 2003

15. Issues/Future Steps
Scope and content of future research direction on trajectory prediction
A trajectory prediction action plan as been proposed to the Eurocontrol/FAA R&D committee
Recommend that this initiative be used to agree upon and chart future, joint research
Recommended research areas for additional emphasis:
Decision making under uncertainty
Automation/weather integration
Farther-term ATM concepts for DSTs: do we have a research-gap issue?
27 June 2003

16. Issues/Future Steps
Concern: data link communications development status
Key element of virtually all, proposed future concepts
ATM researchers have key role to play in defining future services roadmap and in quantifying benefits to strengthen Business Case
As more information and capabilities become available to support user decision making, we need to be better able to :
Evaluate the effectiveness of solutions (are they really better?)
Define criteria by which to make decisions based on new info
Ensure we consider all players
e.g. need to define roles of AOC and pilots in TFM decisions explicitly discussed during our sessions
