Configure each GI 275 for a NAV source for NAV 1 or NAV 2 (if equipped) per the settings in Table 5-6.
Table 5-6 NAV Interfaces and Configuration Settings
Notes:
[1] If Course Selection is disabled, configure CRS A429 port and speed.
[2] Disabling the Transmit Selected Course to the GTN configuration setting will prevent the course
selected on the GI 275 from crossfilling to the GTN 6XX/7XX or GTN Xi. Disable this setting when
the GI 275 has Course Selection enabled but is not the primary HSI/CDI interfaced to the GTN.
Course Selection
Disabling Course Selection allows the GI 275 to slave to the Selected Course from an external source. Set
the Course Selection to Disabled when an external system is providing the primary Selected Course data.
Set the Course Selection to Enabled when the GI 275 is the primary source for selected course data. The
Pilot Control configuration setting for Course Selection is not currently approved under this STC.
