This paper presents a preliminary, simplified application of the System Response Generator (SRG) concept, i.e. the use of simulation approaches in the form of a software tool for analysing the influence of human decision making and action on accident evolution. The study focuses on the dynamic aspects of the pilot-airplane interaction and on pilot errors, with reference to the case of a Boeing 747 type aircraft during a well defined transient situation, ATL (the Approach phase To Landing). Three components play a role in the proposed method: the deterministic simulation of the aeroplane and its control mechanisms, the simulation of the pilot behaviour and a model for the generation of failures/errors. The simulations of the aeroplane and the pilot behaviour are described in detail. The error module has been based on a simple generator of systematic events of omissions of proceduralised actions, and hardware failures are not considered. The results obtained by applying the methodology to a well defined case of ATL are then compared with the data obtained by performing a classical human reliability study for the same case. The potential applications and outcome of the proposed method are enhanced by the comparison.
