NOTE:
When an external GPS navigator is in use, the pilot cannot change
the CDI scale.
Three factors determine the default distance from the center of the CDI to full left
or right limits:
• CDI scale = 1.25 nm - within 30 nm of any airport in the active route.
• CDI scale = 0.25 nm - on an approach leg or within 2 nm of the FAF or MAP.
• CDI scale = 5.0 nm - if the previous two conditions do not exist.

The G3X will automatically slew the LOC course pointer to the correct final approach
course when an ILS, LOC, BC, LDA, or SDF approach is active in the external navigator
and the appropriate CDI and navigation source are selected on the G3X.
