Flight Inspection of GPS Nonprecision Approaches

Thomas Fischer, Thomas Izard

Abstract:	In the near future, GPS, with various augmentations, will be used for many phases of flight. Already the FAA has developed nearly 1,763 GPS nonprecision instrument approaches and has published 925 of them. The primary objective of inspecting GPS nonprecision approaches is to evaluate the waypoint data accuracy for each point contained in the standard instrument approach procedure. A second goal is to evaluate the GPS instrument approach procedure to ensure safety and flyability. This paper discusses the design, development, and implementation of an automatic flight inspection system that is used for the inspection of GPS nonprecision approaches. Points of interest include database integrity, instrument approach procedure, position determination and interference.
