- the introduction of advanced computer assistance tools to assist the Planning Controller with his task of planning conflict free trajectories through his sector;
- the increasing use of datalink functionality and the resulting increased information content.

The environment was en-route airspace in the timescale circa 2000 simulating several en-route sectors and emulating entry and exit conditions at TMA sectors. PHARE Demonstration 1 simulated a two-man sector operation applied to the NERC sectors 10 and 11. Each sector had a Tactical Controller (TC) and a Planning Controller (PC).
It was envisaged that the controller's basic roles of planner and tactical would not be subject to major changes but assistance would be provided in terms of "computer assistance tools" and datalink. The new elements supported the definition of a new control method, based on “current” practices, but improved and adapted to provide advanced planning facilities for the Planning Controller and datalink clearances for 4D equipped aircraft.

It was this advanced planning capability that was expected to lead to increased capacity. The fact that ATC was performed in a similar manner to “today's” operation (i.e. maintaining the basic roles of planner and tactical together with the same sectorisation) considerably reduced the number of options to be considered.
There were no paper flight strips, the information that is normally held on the flight strips was presented to the controllers electronically using various Human Machine Interface techniques.
PD1 comprised three "organisations". In all cases there was a mixed aircraft population and the airspace was based on NERC sectors 10 and 11. The major concepts which characterise the organisations are as follows:-
|
|
|
|
ORG 0 Reference Baseline organisation |
- up to 10 minutes of planning anticipation (as in current systems);
- mixed aircraft population (as foreseen for year 2000) with 3 flow rates (low, medium and high);
- current controller roles of Planner and Tactical will be maintained;
- derived from ODID III (Organisation 2) which operates without paper flight strips and with simple tools based on 10 minute look-ahead (e.g. Conflict Risk Display, Entry/Exit Aids);
- airspace NERC sectors 10 and 11 with adjacent feed sectors.
|
|
|
- up to 20 minutes of planning anticipation;
- mixed aircraft population (as foreseen for year 2000) with 3 flow rates (low, medium and high);
- computer assistance derived from the PHARE Advanced Tools PHARE Demonstration 1 Toolset:
Conflict Probe (CP)
Trajectory Predictor (TP)
Flight Path Monitor (FPM)
Problem Solver (PS);
- controller methods reflect the extended look ahead and conflict free planning;
- downlinked data is available from aircraft;
- airspace as ORG 0.
|
|
|
- computer assistance as for ORG 1 with the inclusion of the PHARE Advanced Tools Negotiation Manager;
- mixed aircraft population (as foreseen for year 2000) with 3 flow rates (low, medium and high). 30% and 70% ratio of 4D Flight Management System equipped aircraft introduced in traffic samples; a live aircraft, the DRA (Bedford) BAC 1-11 will be included in this Organisation.
- two-way datalink capability within pre-defined protocols, 4D trajectory and ATC clearance exchange;
- airspace as ORG 0.
