De l'intérêt d'observer l'erreur humaine en situation de simulation de vol: prédire et concilier la relation humain-machine

This paper describes an epidemiologic study on difficulties of use, observed during cockpit design assessment campaigns. Design a product requires to anticipate, to envisage the future modes of use, to test them and provide solutions in term of adjustment of performance man-man and man-machine to reconcile an optimal human-machine interaction. In addition to the precious data on pilots behaviors (strategy, performance), assessments results prove the convergence and the maturity rise of our design process. Finally, the analysis highlights methodological improvements within the construction of assessments scenarios in order (i) to track the human difficulties of use and errors with adequate abstraction levels, (ii) to handle all errors types in relation with novelties and (iii) generally to increase the confidence level on the data required and collected. In particular, attention to be put to integrate innovations or novelties in an existing cockpit.
