Human Factors and Operations Issues in GPS and WAAS Sensor Approvals: A Reviewand Comparison of FAA and RTCA Documents

摘要

This report is the culmination of the first task in a project to evaluate humanfactors and operations issues associated with the integration of Class C Global Positioning System (GPS) sensors and Class Beta GPS/Wide Area Augmentation System (WAAS) sensors into navigation systems in low-end transport category aircraft. The objective of the project is to provide aircraft certification specialists with information that will help them in the evaluation of GPS and GPS/WAAS sensors within integrated navigations systems. The first task of the project was to compare the requirements of the various FAA and industry documents currently used in the approval of GPS and GPS/WAAS sensor equipment and installation. The impact of the use of required navigation performance (RNP) standards on approval also was evaluated. This document describes both the GPS and GPS/WAAS navigation systems and equipment classifications.
