ILS Approach
GNS 530W only
NOTE: If you attempt to intercept the approach course
at a distance less than 2.0 nautical miles from the FAF,
the GNS 530W does not automatically switch the CDI
to VLOC. In this case, press the
CDI key to manually
switch from GPS to VLOC.
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 press-
ing the
CDI key. Once the switch from GPS to VLOC
has occured, either automatically or manually, it does
not automatically switch again until the approach is
reactivated or another approach is selected. To prevent
automatic ILS CDI selection, choose the “Manual” ILS
CDI setting (the factory default setting is “Auto”, which
enables the automatic switch to VLOC) - see AUX
- Setup 1.
Within the shaded area of the previous run-
way illustration, the GNS 530W automatically
switches the external CDI to the GNS 530W’s
internal VLOC receiver. “VLOC” appears
above the CDI key.
Selecting an ILS Approach
For this example, we’ll use a flight from Laughlin
Bullhead (Arizona) International (KIFP) to Flag-
staff Pulliam (KFLG) and select the ILS runway 21
approach. “SHUTR” intersection is selected as the IAF,
which includes an outbound leg and a procedure turn.
Of course, vectors-to-final could also be selected, as
previously described for the non-precision approach
examples.
