Paper Abstract

The Darmstadt University of Technology (TUD) develops displays with 3D terrain depiction to improve pilots spatial situation awareness. This will enhance safety and will lead to economical benefits by supporting new traffic procedures (i.e. SMGCS taxiing). Flight tests and simulation with a first generation of displays gave proof of the concept. However, for global usability it was necessary to rebuild the software concept. Displays of second generation utilise a worldwide database instead of a local and experimental one. With this new software concept either the database of the tools, to build it, should be certifiable. For performance reasons, logic information is included in the database. This means that the animation information about special objects is described in the database and not in the display software routines. This was the motivation to implement a new version of the software instead of an update of the first generation. A graphics library, written to build 3D graphic applications is used. This library makes optimal use of the graphic hardware and supports database. The new version provides a lot of flexibility, without decreasing the performance of the displays software. It is build for experimental research and not as a final product. The display format must have a lot of flexibility, because the software is contributing to different research projects in different configurations. It is also necessary to have a great flexibility for the interface configuration. Important steps in the development process of TUD's second generation Synthetic Vision Displays will be presented. Furthermore, features of the drawing process and the communication interface of the software will be explained.
