Measuring and Testing Area Navigation Procedures with GNSS

Abstract

This paper deals with the flight testing and measuring of the GNSS (RNAV) with flying laboratory – AeroLab 1 at the University of Žilina. The paper focusses on the comparative aerial measurements of the GNSS RNP APCH which is approved and published at the Žilina airport. The GNSS procedure was put into operation in May 2017 and is subjected to regular checks. Results of flight checking must be within the limits of the prescribed tolerances defined in the ICAO Annex 10. Our practical measurements were divided into two flights. The displayed outputs on the console were compared with the reference values and subsequently evaluated in the conclusion in this paper. Our practical comparative measurements show results that comply with ICAO standards and thus the tested RNP APCH is functional and can be used in mountains and river areas.
