The incorporation of cathode-ray tube displays in flight simulator instructor stations will permit the masses of data available in the simulator to be organized for more rapid, meaningful interpretation. The CRT can display relevant data, when needed, in any format appropriate to each instructional task. Experience with current CRT instructor stations is reviewed, together with the instructional tasks accomplished in flight simulators. Recommendations are made for the further definition of the simulator instructor's tasks, and for the extended application of CRT'S. Emphasis is placed on the analysis of requirements for the display and formatting of instructional information.
