RSM GPS Reversionary Navigation
Auto Range is only available when a ight plan is active. Since Auto Range uses the
distance between the present position and the next active waypoint to compute the
appropriate map range, if the currently Selected CDI Navigation Source does not have
a valid ight plan, then Auto Range is not selectable. If the Auto Range cannot be
selected, check:
• To ensure a ight plan is active
• The GPS source with the ight plan is the Selected CDI Navigation Source
• That Auto Range is enabled from the General Settings B Menu page
4.4.12.2. Flight Plan
When a ight plan is provided by a congured GPS, the map shows ight plan
waypoints and legs. The active leg and waypoint and associated identier are displayed
in magenta. Other waypoints and legs are white. Straight and curved ight plan details
are rotated within the map display to maintain their correct relative orientations at
alltimes.
4.4.12.3. Map Data Source and Reversion
If the selected GPS data is unavailable or invalid:
• The associated ight plan and map data are retained and displayed, as long as an
alternate source of position information remains available.
• The ight plan and waypoints become inactive and are displayed in white.
• Position is provided from:
1. Another congured GPS source if providing valid position data. In this case, a
GPS# REVERSION annunciation is shown above the Selected CDI Navigation
Source (Figure 4-97) (# indicates the congured GPS source that is now
providing the aircraft’s position, either 1 or 2).
2. The RSM GPS, if enabled, and position data are available. In this case, a RSM
GPS REVERSION EMER USE ONLY annunciation is shown above the Selected
CDI Navigation Source (Figure 4-98).
