The insights on human performance gained from the area of human reliability assessment are increasingly being employed in the various safety-critical domains, such as air traffic control (ATC). Research over the years has confirmed the important role of context in which human performance takes place. As a result, research on recovery from equipment failures in ATC requires the precise definition of the context surrounding any failure type. This paper defines context through a set of recovery influencing factors (RIFs). It moves away from the common qualitative approach and proposes a generic probabilistic method to analyze both the context and the ensuing air traffic controller performance. The proposed method provides an assessment of the quality of recovery and thus provides a better understanding of controller recovery overall. The method can be tailored to the specific characteristics of any ATC Centre and the airspace within which it provides its service and is therefore, a valuable tool for the management of safety in Air Traffic Management.
