This article presents a new, holistic model for the air traffic management system, built during
the Vista project. The model is an agent-driven simulator, featuring various stakeholders
such as the Network Manager and airlines. It is a microscopic model based on individual
passenger itineraries in Europe during one day of operations. The article focuses on the
technical description of the model, including data and calibration issues, and presents
selected key results for 2035 and 2050. In particular, we show clear trends regarding …

This article presents a new holistic model for the air traffic management system built by the
Vista project. The model studies the alignment and trade-offs of key performance indicators
in the 2035 and 2050 horizons. It is based on three layers modelling the strategic, pre-
tactical and tactical phases of ATM. It heavily features multi-agents, is highly data-driven,
and includes highly microscopic models. It is runnable as a 'what-if'tool and has been
applied to different scenarios, including long-term forecasts for 2035 and 2050. The results …
