Abstract : The Warner-Robins Air Logistics center has initiated a program to replace the current cockpit flight instruments with a new Control/Display System (CDS). The new CDS includes (1) Liquid Crystal Display (LCD) units for the presentation of electronic Primary Flight Display Formats and (2) the addition of a Display Avionics Management Unit (DAMU) for controlling primary flight and navigation functions. The Wright Laboratory Cockpit Integration Division has supported this upgrade program through a two-phase pilot-in-the-loop simulation evaluation effort. In Phase the PFD format and the DAMU were evaluated in part-task simulations. In Phase II, a full mission evaluation was conducted to verify that the integrated system would support C-141 mission requirements. This report describes the methods and results of the part-task simulation. Four primary flight display formats (CDS Attitude, CDS Climb-Dive, C-141, and the T-1) were compared through a series of instrument flying tasks. Performance with the CDS displays was as good as or better than the others. However, numerous deficiencies were identified through questionnaires and pilot comments. Two DAMU menu designs (proposed CDS design, and a WL/FIP alternative design) were compared using a scripted role-playing task. Overall, performance and subjective results showed that both DAMU designs would be suitable for use in the C-141 with minor modifications. Specific recommendations are provided for both the CDS PFD format and DAMU design.
