PHARE Advanced Tools (PATs)

PHARE Logo
PHARE toolbox
The PHARE concept required that air traffic controllers be supported by a set of advanced ground-based tools. There were nine tools developed which were collectively known as the PHARE Advanced Tools (PATs). These were:
  • Arrival Manager
  • Conflict Probe
  • Cooperative Tools
  • Departure Manager
  • Flight Path Monitor
  • Negotiation Manager
  • Problem Solver
  • Tactical Load Smoother
  • Trajectory Predictor
The tools concept was built around the capability of aircraft to follow an agreed 4-Dimensional trajectory with a high degree of accuracy. The trajectory in the ground system would be identical to the trajectory in the aircraft flight management system, thus increasing the confidence in the conflict detection (Conflict Probe) and resolution (Problem Solver). The ground system Flight Path Monitor would alert the controller to any deviation of the aircraft from the trajectory.

The Departure Manager and the Arrival Manager provided sequencing and runway load balancing, the Problem Solver and Co-operative Tools aided problem solving and deconfliction. The Negotiation Manager provided silent handover, ground-ground co-ordination and air-ground trajectory negotiation. The Tactical Load Smoother calculated future airspace complexities, allowing a multi-sector planner to reduce complexity and thus potentially reduce workload at sector planner level. The sector planner was provided with support to deconflict aircraft prior to sector entry and conveying the trajectory change information, via datalink, to the 4D aircraft’s FMS, thereby reducing the Tactical Controller workload to monitoring aircraft with 4D FMS and controlling the less well equipped aircraft in accordance with the plan developed by the sector planner.
