NOTE: If you attempt to intercept the approach course
at a distance less than 2.0 NM 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.

- 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.
