Abstract : This report documents a study which applied an analytic method known as the Controls and Display Evaluation Model, or CODEM, to the flight deck avionics improvements identified in the Flight Control Division's (AFWAL/FIGR) Tanker Avionics and Aircrew Complement Evaluation (TAACE) program. TAACE, in support of the USAF KC-135 Avionics Modernization Program, sought to establish design criteria for the controls and displays of improved avionics, in the event the crew of the KC-135 is reduced by eliminating the navigator. The objective of this study was to apply CODEM to a previously evaluated design, so that the resulting data could be used to evaluate the validity of CODEM by comparing the two sets of data. CODEM, which is still in the developmental stage, embodies a 'limit design' approach to the problem of controls and displays engineering and integration. Absolute design limits and progressive tests are used to test the emerging design in terms of task complexity. CODEM output consists of plots of task complexity vs. time and a printout of associated equipment-related tasks which allows the designer to diagnose the source of any undersirable crew loading. CODEM's application to the TAACE flight deck design concluded that the air-refueling mission could be performed without excessive workload on the crew.
