DME/VOR/GPS/LOC UPDATE
Push – permits switching between ON and OFF modes for updating FMC
position. Default mode is ON for VOR, GPS and LOC. DME defaults to OFF. The
current mode is highlighted.
Note:
When the DME UPDATE is OFF, the VOR-DME and LOC-DME
UPDATES are also inhibited even if the VOR and LOC UPDATES are
selected ON. If the FMC hasn’t done a GPS UPDATE in the last 5 seconds
then the FMC can do a LOC only UPDATE without DME if the LOC
UPDATE is selected ON and the DME UPDATE is selected OFF.
Selections are reset to ON at flight completion except for DME which is reset to
OFF.
Fix Information Page
Two identical FIX INFO pages are used to identify waypoint fixes for display on
the navigation display map mode. If desired, fix information can be copied into
the route. Page access is via the FIX key.
Radial or distance entries from the fix may be made on any line 2L to 4L. Valid
format is a three character numeric entry. Slash rule is used to differentiate
between radial and distance in the scratch pad.
