Abstract

Enhanced and synthetic vision applications for flight guidance are on the verge of commercialisation and wide-scale employment. The paper will first give an overview at the characteristics and benefits of these types of displays, and focus afterwards on their implementation in an integrated modular avionics environment. The Enhanced/Synthetic Flight Guidance Display is a promising approach to the solution for the problems of poor visibility low-level flight. It yields a computer-generated three-dimensional cockpit view and can optionally be combined with an imaging sensor (e.g. FLIR, mmWR, LL-TV). The paper will provide details on the technical concept and the evaluation of a functional prototype in flight trials. After functional validation, a enhanced/synthetic vision display was chosen to be ESGs first avionics application to be transferred into an integrated modular avionics architecture. This software prototype implementation takes into account the results so far achieved in the Allied Standard Avionics Architecture Council (ASAAC) programme. The effort of this programme to define an open system architecture will be addressed in the paper. The architecture's characteristics of a clearly defined layer structure and its strict hardware-software separation will be explained. Finally the paper addresses the allocation of the functions necessary for the synthetic vision display. It explains how database access, I/O to other systems, numerical calculation and graphics generation are mapped to IMA-based mass memory, data processing and graphics processing components. The paper finishes with the presentation of first successful implementation results.
