If an approach is loaded when another approachis already in the active flight plan, the new approach replaces the previous approach. The route is defined byselection of an approach and the transition waypoints.Whenever an approach is selected, the choice to either “Load” or “Load and Activate” is given (“Load andActivate” is only available for the active flight plan). “Loading” adds the approach to the end of the flight planwithout immediately using it for navigation guidance. This allows continued navigation via the intermediatewaypoints in the original flight plan, but keeps the procedure available for quick activation when needed.“Activating” also adds the procedure to the end of the flight plan but immediately begins to provide guidanceto the first waypoint in the approach.When selecting an approach, a “GPS” designation to the right of the procedure name indicates the procedurecan be flown using the GPS receiver. Some procedures do not have this designation, meaning the GPSreceiver can be used for supplemental navigation guidance only. If the GPS receiver cannot be used forprimary guidance, the appropriate navigation receiver must be used for the selected approach (e.g., VOR orILS). The final course segment of ILS approaches, for example, must be flown by tuning the NAV receiver tothe proper frequency and selecting that NAV receiver on the CDI.The SBAS GPS allows for flying LNAV, LNAV+V, LNAV/VNAV, LP, LP+V, and LPV approach service levelsaccording to the published chart. LNAV+V is an LNAV with advisory vertical guidance provided for assistancein maintaining a constant vertical glidepath similar to an ILS glideslope on approach. This guidance isdisplayed on the system PFD in the same location as the ILS glideslope using a magenta diamond. In all caseswhere LNAV+V is indicated by the system during an approach, LNAV minima are used. The active approachservice level is annunciated on the HSI as shown in the following table:HSI Annunciation Description Example on HSILNAV RNAV GPS approach using published LNAV minimaApproach Service Level- LNAV, LNAV+V, L/VNAV, LP, LP+V, LPVLNAV+V RNAV GPS approach using published LNAV minima.
