The system automatically switches from GPS to LOC navigation source and changes the CDI scaling accordingly
when all of the following occur:
• A localizer or ILS approach has been loaded into the active flight plan
• The final approach fix (FAF) is the active waypoint, the FAF is less than 15 nm away, and the aircraft is moving
toward the FAF
• A valid localizer frequency has been tuned
• The GPS CDI deviation is less than 1.2 times full-scale deflection
GPS steering guidance is still provided after the CDI automatically switches to LOC until LOC capture, up
to the Final Approach Fix (FAF) for an ILS approach, or until GPS information becomes invalid. Activating
a Vector-to-Final (VTF; see the Flight Management Section) also causes the CDI to switch to LOC navigation
source; GPS steering guidance is not provided after this switch.
