PHARE’s Achievements

  • Outline the Achievements of PHARE

  • Specific results and lessons learnt are covered in other presentations

  • Spin-offs from PHARE for early implementation and further development

  • Highlight the successes, not hiding the items which did not work

  • Influence on the future ATM R&D in Europe

  • ATM R&D coordination

Potential atm research issues as seen in 1990

Potential ATM Research Issues as seen in 1990

  • Airborne and ground systems interaction

  • The possible and acceptable level of automation support

  • The man-machine interaction

  • The influence of airspace organisation and

  • The procedures applied by ATC

Key phare research topics

Key PHARE Research Topics

  • Full use of the capabilities of the aircraft’s systems , Development of the Experimental Flight Management System

  • Advanced automation support for controllers

  • Ground Human Machine Interface for operating such automation support

  • Use of datalink for the exchange of information between air and ground, in particular for the process of trajectory negotiation

  • Better meteorological forecasting to improve the trajectory prediction

  • Use of common methodology and standard tools/ procedures for validation.

The phare programme

The PHARE Programme

  • Progressive increased collaboration :

    • Exchange of information and harmonisation of tools

    • Formulation of common goals and exchange of results

    • Definition and execution of shared and commonly financed activities

  • Merging of “bottom-up” and “top-down”, definition of a structured research programme

  • 11 Projects with defined timescale and budget frame

  • Basic PHARE Agreement complemented by a special agreement for each project

Phare studies

PHARE Studies

  • “Medium Term Scenario 2000-2015” Description of the PHARE Concept

  • Complemented by :Detailed operational specifications and scenario descriptions for each of the PHARE Demonstrations

  • “Operational experiments within PHARE”

  • “The role of the man within PHARE”

  • “PHARE Air-Ground Data Exchange”

Airborne programme 1

Airborne Programme (1)

  • Airborne Programme: two closely relatedprojects

    1.Experimental Flight Management System (EFMS)

    2.Airborne Human Machine Interface (AHMI)

    EFMS Development

    • to demonstrate the capabilities of advanced 4D FMS

    • to negotiate “User preferred trajectories”

    • to guide the aircraft on that trajectory in space and time


    • to allow pilots (of live research aircraft) in a realistic cockpit environment to participate in the real-time simulation experiments

Airborne programme 2

Airborne Programme (2)

  • EFMS and AHMI deployed in

    • VFW (Advanced Technology Testing Aircraft) of DLR (Germany)

    • CESSNA CITATION II of NLR (The Netherlands)

    • BAC1-11 of NATS/DERA

    • the Multi-Cockpit Simulator (Boeing 747) of EUROCONTROL Experimental Centre (Brétigny, France)

  • Airline pilots participated in

    • specific evaluation of these systems

    • PHARE Demonstrations

  • Overall great success

    • Concept of 4D Navigation readily achievable

    • Direct manipulation of trajectories appreciated

    • Trajectory negotiation quickly assimilated

Phare common modular simulator cms

PHARE Common Modular Simulator (CMS)

  • Aimed at providing an environment for interfacing software components from the different partners and providing a platform for initial testing

  • Definition of an open modular architecture and Application Programming Interfaces

  • Prototype development of such common platform showing the technical feasibility of its approach , successfully achieved

  • Full application for PHARE Demonstrations has not been achieved

  • CMS project has contributed significantly to the present definition of a European ATM integration platform

Phare advanced tools pats set

PHARE Advanced Tools (PATs) set

  • Common Definition and Development of nine Advanced Tools by separate teams of the partners

  • No missing functionality or tool was found in the experimental trials, however some conceptual mismatches

  • The objective of each tool was achieved and all were used in one or the other PHARE trial

  • The objective to use all tools together in one tool-set in the PD/3 trials was not successfully achieved

  • The Demonstrations showed that some tools provided considerable advantages even without data link and 4D trajectories

Phare ground human machine interface ghmi

PHARE Ground Human Machine Interface (GHMI)

  • Elaboration of Human-Machine Interface specifications by an international team of human factors specialist, engineers, operational experts

  • Advanced features used : Colour, windowing, features of standard software tools

  • Highly successful, major contribution to a quasi standard future HMI

Phare aeronautical telecommunications network patn

PHARE Aeronautical Telecommunications Network (PATN)

  • Datalink is a key element of the PHARE concept

  • PHARE Demo 1 used enhanced Mode-S capabilities

  • PHARE Demo 2 used a dedicated high speed VHF data link

  • For PHARE Demo 3 an experimental Aeronautical Telecommunication Network (using the SATCOM subnetwork) was set-up

  • Disappointing performance of the SATCOM subnetwork

  • More work needs has to be done (and has started) using commercial data link to demonstrate their capabilities for future ATM applications

Phare meteorological project

PHARE Meteorological project

  • Additionally contracted Partners :

    • UK MET office

    • METEO France

  • Successful development and test of a numerical prediction model using aircraft derived down-linked data to achieve an improved weather “nowcast”

  • Not used in real-time as component of the PHARE Demonstrations

  • Considered as a potential solution for future implementation

Phare validation project

PHARE Validation project

  • Development of a common methodology

  • Production of recommended Measures of Merit for evaluating trials results

  • Production of analytical methods for assessing trials measurements

  • Successful application of these principles in the PHARE Demonstrations

  • Major contribution to the definitions in the “EATMS Validation Strategy Document” which is considered the basis for ongoing validation activities within the European ATM R&D

Phare demonstration results

PHARE Demonstration Results

PD/1 & PD/2: Significant results. Potential for increase in traffic throughput/reduction of controller workload

PD/3: Did not fully satisfy expectations.

In general, the PHARE Demonstrations confirmed :

  • feasibility of PHARE Concept

  • assumption of high accuracy flying of 4D trajectories

  • possibility of de-conflicting of aircraft up to about 30 min. ahead

  • acceptability of automation tools

  • benefits even in a mix of not fully 4D FMS equipped aircraft

  • requirement for good performance data link for achieving full benefit

Spin offs


Spin-offs relate to the

  • progressive alignment of understanding on a possible advanced ATM concept

  • deliverables and products developed

  • orientation and co-ordination of ATM Research and Development

Influence on atm r d and co operation

Influence on ATM R&D and Co-operation

  • European understanding and mind-setting

  • PHARE-X Association

  • Development of an R&D Strategy in support of EATCHIP

  • Set-up of European ATM R&D Programme Review Group, Prioritisation of R&D topics contributing to ATM2000+ Strategy

  • Stimulation of co-operation between the European Commission and EUROCONTROL

  • Co-operation with the US FAA and NAV Canada



  • “CARE” (Co-operative Actions of R&D in EUROCONTROL)

  • Co-operation has value

  • Areas of improvement identified and to be applied in “CARE”

  • PHARE has found its successor

  • PHARE achievements will contribute to the success of “CARE”.
