1 ©2016 INAIR - International Conference on Air Transport GNSS Final Approach Trajectory Analysis for General Aviation Aircraft

Standalone on-board GNSS systems used in general aviation are sufficiently accurate and precise to be used as part of instrument approach procedure. The number of standalone on-board GNSS systems on general aviation aircraft is increasing at high rate. Many of general aviation pilots use standalone on-board GNSS systems as a supplementary means of situational awareness when flying. Accuracy and precision of positioning of those systems are two critical elements for flight safety in final approach phase. Unlike the conventional ground based navigation systems such as ILS, VORs and NDBs, standalone GNSS receivers which are not integrated in aircraft avionics still need testing in order to prove their applicability for general aviation under IFR conditions. Aircraft trajectory was analyzed during final approach phase of flight in terms of accuracy and precision in order to determine the horizontal and vertical deviations from ideal approach path. Trajectory analysis proved that standalone on-board GNSS systems used in general aviation are accurate and precise enough to be safely used as part of instrument approach procedure.
