5 - PROCEDURES108 190-00357-00 Rev GNOTE: If you attempt to intercept the approach courseat a distance less than 2.0 NM from the FAF, the GNS530W does not automatically switch the CDI to VLOC.In this case, press the CDI key to manually switch fromGPS to VLOC.The automatic switch from GPS to VLOC is notimmediate, but instead occurs gradually to preventabrupt CDI changes when coupled to an autopilot. TheCDI selection can also be changed manually by press-ing the CDI key. Once the switch from GPS to VLOChas occured, either automatically or manually, it doesnot automatically switch again until the approach isreactivated or another approach is selected. To preventautomatic ILS CDI selection, choose the “Manual” ILSCDI setting (the factory default setting is “Auto”, whichenables the automatic switch to VLOC) - see AUX- Setup 1.Within the shaded area of the previous run-way illustration, the GNS 530W automaticallyswitches the external CDI to the GNS 530W’sinternal VLOC receiver. “VLOC” appearsabove the CDI key.Selecting an ILS ApproachFor this example, we’ll use a flight from LaughlinBullhead (Arizona) International (KIFP) to Flag-staff Pulliam (KFLG) and select the ILS runway 21approach. “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, aspreviously described for the non-precision approachexamples.Flagstaff (AZ) PulliamILS DME Rwy 21DO NOT USE FORNAVIGATION 1.
