Synthetic Vision System Terrain Database Integrity Based on DWL

doi:10.3969/j.issn.1006-2475.2015.10.007

Abstract

Abstract: Synthetic vision system (SVS) is an effective solution of controlled flight into terrain (CFIT). In recent years, the national key basic research development plan has brought into the related research on synthetic vision system to study. The study of synthetic vision system terrain database integrity is an important part of the SVS research. Based on the present stage, most aircrafts are equipped with GPS, radar altimeter and other equipment, this paper is about a study of synthetic vision system terrain database integrity based on downward looking (DWL). The real-time monitor of synthetic vision system database based on DWL can effectively guarantee the integrity of the vertical database data, but for aircraft horizontal database data integrity, the assurance ability is also slightly insufficient.

Key words: synthetic vision system (SVS), integrity, CFIT, real-time monitor, DWL
