This paper describes an Electronic Flight Progress Strip (FPS) display and a color Plan View Display as a laboratory prototype. The purposes of prototype development are to examine the effectiveness of the Electronic FPS and to clarify problems of that in comparison with the current system using the Paper FPS. The purpose is also to identify the controller-workstation requirements, which are necessary to decide a future planning of a production prototype development.

The evaluation was conducted with 26 trials of 6 typical en route sectors. It was found that Electronic FPS was useful in the normal and busy traffic load. The busy traffic load is nearly equal to the specified capacity used in current Air Traffic Flow Management. Also the results show the opposite behavior of rate of written or inputted depends on the contents of scenario. Electronic FPS is proved to be useful even for the heavy traffic load in the sector in which the rate of overflight is high.
