A global improvement and consolidation of the Phare Scenario is necessary to ensure its consistency. Also consensus between the different participants involved must be reached, taking into account their respective needs.
The AEGIS consortium is a multi-disciplinary group consisting of Academic and Industrial Institutions who have not contributed, until now, to Phare Scenario elaboration and will bring their knowledge and expertise in specific methods and techniques (for example, HMI), as well as organizations well aware of ATM problems. Some of the latter have participed in Phare programme elaboration and have been responsible for the complementarity of this programme and the consistency of the whole study.
The objectives of the AEGIS study are: to explore new aspects of the problem, taking advantage of the multi-disciplinary origins of the group; to ensure that a common approach is adopted by all the participants, including Industries, Academics and Airlines. An outcome of this study could be the identification of additional research in areas not covered in Phare, Such as interaction between airlines and ATC or ground movement problems.
The analysis performed during critical analysis and comparison of scenarios of the AEGIS study has produced the following results:
an initial air traffic managment (ATM) description, which will evolve according to the work;
a classification of scenarios;
a list of concepts;
a first of list quality standards (for scenario assessment).
The work performed on the concepts assessment has produced the following results:
identification of concepts;
identification of assessment criteria;
list of concepts assessed.
The extent to which the objectives for the critical analysis and comparison of scenarios have been met has been evaluated. The selection of scenarios is not exhaustive and it could be argued that some national, regional or worldwide documents have been omitted. Nevertheless, it can be assumed that the sample of analyzed scenarios provides an acceptable vision of the trends of evolution in the ATM situation. The comparison of scenarios provided an outline to be enriched by further work. In order to take advantage of the different expertise of the participants in the AEGIS project, a common culture has been established by introducing ATM to novice participants in particular fields of ATM.
The EURET programme identifies in its topic 1.4 a need for industrial contribution to the Phare programme for demonstration of AIR/GROUND cooperation feasibility. In this context, the PHARE scenario has been developed to shape the future ATC system. Nevertheless, the complexity of such a task requires a large amount of human effort and expertise in different technical fields.
Moreover, enlarging the area of investigation will considerably improve and consolidate the European and International scenarios related to ATM. That is the purpose of the AEGIS programme (ATM European Group for Improvement of Scenarios).
Up to the present, the interaction between airline operators and ATM has not been studied, except in CATMAC and only to a certain extent. AEGIS will thus make a significant contribution in this area, by adding new elements to preexisting scenarios.
Another significant contribution will be development of general methodologies, analysis and activity models, scenario definitions, cost/benefit models and metrics which will be applicable to similar problems.
AEGIS will gather complementary expertises and proposes the following approach:
The "first workpackage" will logically consist of a critical analysis and comparison of all the available scenarios.
Nevertheless, most of these scenarios concentrate on ATM. In order to extend the area of investigation, "workpackage 2" will be a critical analysis of the available concepts in the revelant technical fields.
The following "workpackage 3" will necessarily consist of a more precise definition of a scenario. The description of its main components will provide the framework used in "workpackage 4" to consolidate a set of scenarios.
The improvement of this set will then be conducted through "workpackages 5 to 7" with respective consideration given to the environment field, organization field, technical requirements and transition feasibility.
It is recognised that cost/benefit analysis is of prime importance for the evaluation of scenarios. For this reason it will be covered by "workpackage 8". "Workpackage 9" will be the conclusion of the present AEGIS programme, characterized by the choice of the most promising scenario with complementary cost/benefit analysis and improvement.
This chosen scenario will in fact only be the basis for simulations, validations or preoperational experiments preceding the detailed design and implementation of the ATM system. That is why the AEGIS programme will propose a set of complementary studies and actions defined in coordination with ongoing Phare programme developments (EFMS, CMS, etc).
