This paper demonstrates how the flight deck of a derivative aircraft was optimized within the rigid constraints of existing structure, avionics, and performance features. The new design effort utilized three-dimensional computer modeling, combined with iterative, interdisciplinary decision-making. The feasibility of design recommendations made by the interdisciplinary team was analyzed using three-dimensional and solid models of flight compartment interiors and humans. Visual, anthropometric, and comfort considerations were assessed using the McDonnell Douglas Computer-Aided Design and Drafting (CADD) system. AITOFF and perspective projection capabilities were utilized to generate external and internal vision envelopes. The CADD system also hosted a number of computerized human modeling techniques including Crew Station Assessment of Reach (CAR). Articulated Total Body Model (ATBM), a computerized reach envelope, and Touch-and-Draw.
