Performance framework and influence model in ATM

This paper discusses the need for a performance framework (PF) with a methodology to support the assessment of a European-wide concept in ATM. The article describes the work undertaken in Episode 3 (a European Commission Sixth Framework Programme research project) to develop a performance framework based on deliverables from the SESAR definition phase and associated influence models (IM) used to express the links between required performance and proposed improvements, including results from validation exercises. The performance framework includes the SESAR target performance, while the Influence models are an extension of work started in SESAR to trace the relationship between target performance and the SESAR proposed concept. This article also covers the approach, illustrative assessments using the performance framework and influence models, and early lessons learned with an outline of future tasks.
