The objective of the project is toprovide aircraft certification specialists with information and, eventually, with a job aid to help them evaluate GPSand GPS/WAAS sensors within integrated navigation systems. The first task of the project was to compare therequirements of the various FAA and industry documents currently used in the approval of GPS and GPS/WAAS sensorequipment and installation. The impact of the use of Required Navigation Performance (RNP) standards on approval alsowas evaluated. The comparison of the requirements specified in the document is presented in table form and majordifferences are discussed
