The APACHE project proposes a new framework to assess European ATM (air traffic management) performance based on simulation, optimization and performance assessment tools that will be able to capture the complex interdependencies between KPAs at different modelling scales. In this context, a new platform (the APACHE Framework) has been developed in the Project, which is the result of the integration (and enhancement) of different existing tools previously developed by some of the APACHE consortium members. This deliverable is the software availability note of the APACHE Framework. This document firstly describes how the different system components have been integrated into a single workflow, aiming at fulfilling the requirements of the Project. Verification and integration tests of the whole APACHE Framework are presented, showing the successful integration of the different components. Then, validation tests of the individual components of the APACHE Framework are described, taking into account that the validation at system level (i.e. the validation of the whole APACHE Framework as a unified tool to assess ATM performance) is out of the scope of this Deliverable and will be reported in D5.1. Supported by all these tests, the evaluation of the requirements identified in previous Deliverable D3.2 is presented, showing the evidences that proof the fulfilment of requirements and giving a rationale for those (very few) requirements not fulfilled or changed. Finally, this report concludes with a summary of all limitations and assumptions taken when developing the APACHE Framework, aiming at clearly identifying the maturity level of the developed Framework and pointing towards future enhancements and developments of the tool.
