ILS Approaches (GTN 750 Only)

Precision ILS approaches can be performed with the built-in VLOC (VOR/

localizer/glideslope) receivers. The GPS receiver can be used for guidance prior

to reaching the final approach fix, but once there, the proper frequency must

be selected on the VLOC window (right side of screen) and the CDI output set

190-01007-03 Rev. D

The GTN 7XX can be set to automatically

switch the external CDI output from GPS to

VLOC as you intercept the final approach

course (if used with a KAP140/KFC225

autopilot, you will need to manually enable

outputs). See instructions in the "Enabling

Autopilot Outputs for the King KAP140/

KFC225" section. When the ILS approach is

activated (and the correct ILS frequency is

active in the VLOC window), the GTN 7XX

automatically switches 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 illustration shows multiple locations

along the approach path and the CDI

selection that you can expect: GPS or VLOC.

Within the area of the shaded box, the

automatic switch from GPS to VLOC should
