Localizer or VOR-based Approaches
GTN automatically switches the external CDI output from GPS to VLOC as you
intercept the final approach course. When the ILS approach activates and the correct
ILS frequency activates in the VLOC window, the GTN automatically switches to
VLOC within 1.2 nm left or right of the final approach course. This switch can take
place anywhere from 2.0 to 15.0 nm from the FAF.
The automatic switch from GPS to VLOC is not immediate, but instead occurs
gradually to prevent abrupt CDI changes when coupled to an autopilot. The CDI
selection can also be changed manually by tapping
CDI
.
If you attempt to intercept the approach course at a distance less than 2.0 nm
from the FAF, tap CDI to manually switch from GPS to VLOC.

This illustration shows multiple locations along the approach path and the CDI selection
that you can expect: GPS or VLOC. The shaded area depicts where the automatic switch
from GPS to VLOC should occur.
