Abstract : Virtual Prototyping provides an opportunity for control engineers to observe and evaluate their designs in a "real world" setting without the costs or risks associated with flight test. Designers Workbench is a computer aided design tool that allows a user to create, view, modify and animate three-dimensional databases. These may include instruments, avionics displays and any out-the-window applications such as runways or terrain. The dynamic behavior of specific elements can be observed by linking data to the desired element. In this way a realtime animation of the simulation can be generated. The animation provides another analysis tool for the designer, by representing data in a more intuitive environment. Data files from two separate controller simulations was used. Cockpit instrumentation was modelled and used for each animation to monitor the aircraft states. In addition, each animation had an out-the-window perspective to view the aircraft model as it flew the prescribed trajectory.
