This paper discusses an evaluation program designed to determine the acceptance and effectiveness of an Electronic Library System for commercial flight operations. The program's objective was to determine the needs and applications of the end users, the flight crew, prior to the design of such a complex avionics system. The evaluation program involved over 40 pilots and included testing in a training/classroom environment and in operational flight scenarios in a B727 simulator. In addition to overwhelming acceptance of the Electronic Library System concept, the results of this program demonstrated the importance of a well-designed graphical user interface for flight deck applications.
