MAEVA - A Master ATM European Validation Plan
Overview
Background & policy context:
The validation of air traffic management (ATM) systems is an on-going process which is carried out at the same time as the system is being developed. The detailed definition of validation programmes, methodologies, tests and trials for these systems is a quite complex task.
The major objective of the Master ATM European Validation Plan (MAEVA) Project was to provide the European Commission (EC) with an overall validation strategy for the future pre- European Air Traffic Management Programme (EATMP) for its Fifth Framework Programme (5th FP) validation projects. MAEVA, which was sponsored by the Directorate General for Transport and Energy, was also expected to provide decision-making support in managing all Fifth Framework Programme validation related projects and co-ordinating with Eurocontrol and Member States within an overall European validation initiative.
Objectives:
The objective of the overall Safety Analysis was to assess the safety methodologies that the monitored projects used and applied for high-level safety work performed with respect to ASAS, A-SMGCS, 4D Trajectory Management, and CDM. The purpose of this analysis was to provide guidance to European Commission policy units and other European decision making bodies as to the status and availability of applications developed with documented safety methodologies in the monitored projects. The objective was to present findings, draw conclusions and prezent recommendations regarding future progress in the safety area.. Based on the methodologies used by the monitored projects, an analysis of each project and area was performed. The results of this analysis are described below as findings.
Methodology:
When reviewing all of the monitored projects, one dominating operational safety ethodology was used to a larger extent than others. This is the EUROCAE WG53 / RTCA SC189 methodology. The CARE-ASAS project also used the TOPAZ methodology for risk assessment. For continued development, when addressing the functional safety aspects of the system, different methodologies exit for the ground and airborne segments. The EUROCONTROL EATMP Air Navigation System Safety Assessment Methodology addresses ground issues. A number of welldefined and comprehensive methodologies defined by the SAE address the airborne segment. The EUROCAE/RTCA, TOPAZ, EATMP and SAE methodologies are described in the following subsections.
