Visualization of nonprecision instrument a

摘要

Abstract: In this position paper we propose a synthetic vision software system for visualizing non-precision instrument approaches based on the Virtual Reality Modeling Language (VRML) ISO/IEC CD 14772 standard which is conceptually included in the upcoming MPEG4 multimedia industry standard. In addition to the two dimensional information provided by traditional approach plates the user is presented a three dimensional representation of the approach with the ability to interactively investigate approach parameters. Due to its hardware independence, the system is scalable from general aviation to air transport and defense applications. As a proof of concept, we have modeled the non-precision approach (LOC/DME-C) to Eagle County Regional Airport (EGE) in Colorado. !11
