A wide range of studies has been carried out so far in the domain of delegation of separation assurance to aircraft, leading to various concepts, applications and techniques. The present article is an attempt to provide a framework for analysing these studies from an operational perspective to a more theoretical point of view. The framework is based upon a new dimension – the notion of “level of delegation”. The article addresses the operational aspects, the cockpit aspects through the notion of “level of assistance” and the system point of view through intent, resolution and co-ordination characterisation.
