Evaluation of air traffic management procedures-safety assessment in an experimental environment

This paper presents and discusses the application of safety assessment methodologies to a pre-operational project in the Air Traffic Control field. In the case analysed in the present paper a peculiar aspect was the necessity to effectively assess new operational procedures and tools. In particular we exploited an integrated methodology to evaluate computer-based applications and their interactions with the operational environment. Current ATC safety practices, methodologies, guidelines and standards were critically revised, in order to identify how they could be applied to the project under consideration. Thus specific problematic areas for the safety assessment in a pre-operational experimental project are highlighted and, on the basis of theoretical principles, some possible solutions taken into consideration. The latter are described highlighting the rationale of most relevant decisions, in order to provide guidance for generalisation or re-use.
