Instrument Approaches
If certain GPS parameters (SBAS, RAIM, etc.) are not available, some published approach procedures for the desired airport may not be displayed in the list of available approaches.
If flying Direct-to the Final Approach Fix (FAF), and an instrument approach has been loaded, the system will suspend (SUSP) leg sequencing if the approach intercept angle exceeds 45 degrees.
The system provides guidance for non-precision and precision approaches to airports with published instrument approach procedures. Only one approach per destination can be loaded at a time in a flight plan. The route is defined by selection of an approach, runway, and the transition waypoints.
