Overview System Instruments Flight Additional Features Departure and Enroute Prior to intercepting an active flight plan leg, pathways are displayed as a series of boxes with pointers at each corner that point in the direction of the active waypoint. Pathways are not displayed for the first leg of the flight plan if that segment is a Heading-to-Altitude leg. The first segment displaying pathways is the first active GPS leg or active leg with a GPS overlay. If this leg of the flight plan route is outside the SVX field of view, pathways will not be visible until the aircraft has turned toward this leg. While approaching the center of the active leg and prescribed altitude, the number of pathway boxes decreases to a minimum of four. Pathways are displayed along the flight plan route at the selected altitude for the leg. Climb profiles cannot be displayed due to the variables associated with aircraft performance. Flight plan legs requiring a climb are indicated by pathways displayed at a level above the aircraft at the altitude selected. Descent and Approach EIS CNS Interface GPS Navigation Flight Planning Hazard Avoidance Additional Features Integrated Autopilot Annun/Alerts NOTE: During the final segment of an ILS or WAAS GPS approach, the pathways boxes automatically adjust to correspond with the localizer/glideslope (ILS) or horizontal/vertical (GPS) deviation signals received from the external navigator. When an approach providing vertical guidance is activated, Pathways are shown level at the selected altitude. Pathways are shown level at the selected altitude up to the point along the final approach course where the altitude intercepts the extended vertical descent path or glideslope. From the vertical path descent or glideslope intercept point, the pathways are shown inbound to the Missed Approach Point (MAP) along the published lateral and vertical descent path. During an ILS approach, the initial approach segment is displayed in magenta at the segment altitudes if GPS is selected as the navigation source on the CDI. When switching to the localizer inbound with LOC selected as the navigation source on the CDI, pathways are displayed in green along the localizer and glideslope. If GPS is the selected navigation source on the HSI, the pathways boxes are magenta. If LOC is the selected navigation source on the HSI, the pathways boxes are green for the ILS. Pathways boxes are not displayed for segments such as heading legs or VOR radials. 214 Garmin G3X Pilot's Guide 190-01115-00 Rev. F Appendix Index
