EXECUTIVE SUMMARY:
This document is the first contractual output of WP 1.2.1 “Overall System Specification and integration process definition”. It describes the overall functional architecture of the proposed FLYSAFE systems, including the ground and the airborne segments. The main functions of the FLYSAFE systems are then described in terms of functionality, required inputs and expected outputs.

The ground segment is described as combining information from the Weather Information Management Systems, routine weather data and volcanic ash into the ground-based weather processors which then are defined in terms of coverage in a local and a global processor. The ground-based weather processors are interconnected with the air traffic management. Finally the weather information from the processors can be transmitted to the airborne segment with datalink.
 
Onboard the aircraft, the airborne segment is composed of the systems and functions hosted on the aircraft either functionally inside the perimeter of the FLYSAFE Next Generation Integrated Surveillance System or outside. The functions external to the NG-ISS include aircraft sensors, controls, weather information services, database server, navigation function, flight deck displays and the detection of non collaborative targets. The NG-ISS hosts the weather, traffic and terrain surveillance functions, the fusion functions for weather, traffic and terrain hazards, the alert prioritisation function for tactical operations, the consolidation of weather, traffic and terrain data with a filter to detect conflict for strategic operations, the dataloading, configuration management, maintenance and audio/display management system.
 
This document is the basis for the identification of high level interfaces. A companion Interface Control Document shall be issued as part of WP 1.2.1. Moreover, from the overall architecture and function description, the downgraded version for the FLYSAFE platform architecture will be derived and reported on in the contractual deliverable D 1.2.1-2.
 
This version B integrates the modification raised in the second half of WP 1.2.1 impacting the target product architecture.
