PHARE PHILOSPHYFrom problem to solution domain

• The Problem How to get twice the airspace
  capacity
• One bottleneck is controller capacity
• Solution domains reduce the controller workload
  by...
• Using more controllers (soon exhausted)
• Re-distribute workload over existing controllers
• Shift workload to ATC system
• Shift workload to cockpit (Free Flight)

Air Ground Integrated ATM- key items-

• User Preferred Trajectory from gate to gate
• aircraft optimal trajectory is basis for planning
• System support for ATCo with planning, conflict
  detection, resolution and monitoring
• Digital datalink between air and ground
• Extend the planning horizon
• from tactical to strategic actions
• Close the prediction / control loop

User Preferred Trajectory
Where do we want to go today?
Planned Trajectory
Mmm..., thats okay
Clearance
Conflictsearch
Conflict resolution

Significance of PHARE in relation to other
developments
PHARE Concept
Free Flight
Yes!User Preferred Trajectories in all phases of
flight
Benefit to user
Yes!Freedom to select path speed in FF airspace
Planning
Gate to gate 'continuum' trajectories - 4D
planning for whole flight - seamless
Re-planning needed on entering managed airspace -
short term, 4D Intent trajectories
Required avionics
B-RNAV, 4D FMS, data-link for full benefit
ASAS, B-RNAV, data-link
Required ground systems
4D tools, data-link for full benefit
Conflict detection and resolution, data-link
Separation Assurance
GROUND based
AIR based, ground assistance

Synergy for the Future

• PHARE Concept and Free Flight will live well
  together

• In TMA 4D ground based ATC control is essential
  for scheduling optimal arrival sequence
  (capacity, noise)

• In en-route situations FF is admirably suited to
  fulfill the job.

8
Short term developments

• PHARE Research sees fruitful spin-offs and
  results
• Highly Interactive Problem Solver (HIPS) in
  oceanic application
• Flight Path Monitor, Conflict Probe, Cooperative
  Tools, Eurocontrol Medium Term Conflict Detection
• Ground HMI
• PHARE-ATN
• FMS developments (4th and 5th Framework Programme

To conclude

• The PHARE concept is Air Ground Integrated, 4D
  ATM
• It is designed to assist the controller to
  improve his efficiency, and to redistribute the
  workload over controllers.
• 4D ATM and User Preferred Trajectories directly
  serve the goals of the user (passengers and
  airlines) and environment.
