Evaluation of Intelligent On-Board Pilot Assistance in In-Flight Field Trials

Abstract In this paper the in-flight evaluation of the Cockpit Assistant System CASSY is presented. The design principles, functionalities and the evolution of the intelligent assistant are briefly described. The evaluation program in simulation and flight is pointed out. Interfaces to the pilot, especially speech input, and to ATC are investigated. Results are presented of the situation assessment capabilities concerning pilot behaviour and the complex planning and decision aids, CASSY provides. It is the first system of this kind, which was integrated into an aircraft to be tested in the real aviation environment.
