CFIs and examiners have never taken issue with that.Ī little side-note/reminder that could be a gotcha when switching from GPS to VOR: In GPS mode on the 430 your course deviation indicator will always be showing whatever course you have selected on the GPS regardless of where the OBS knob(radial selected) is, you'll get a MSG alert whining at you to set the OBS but it will display correctly regardless. The way I would fly this approach in my airplane is I'd go ahead and load up the approach in my 530 and leave it in GPS mode but I'd also dial in the VOR on my NAV2 radio and follow the radial on that indicator while leaving the GPS on for situational awareness/reference/cross checking. The GPS can be used as a DME however to identify your fixes. You can use the GPS in GPS mode to navigate to your initial fix but once you make it to the fix you should hit the CDI key to put your indicator into VLOC and actually fly the VOR radial not the GPS since it is a VOR approach not a GPS approach. So here's how I was taught to fly this type of approach and I did use a 430, now a 530 in my new plane. But do you want to get into that discussion during a checkride with a DPE who feels otherwise? Yes, there is a very good argument that parsed correctly, the old AFM Supp language is broad enough to permit what the new guidance says. Although the current guidance specifically permits using the GPS as primary so long as the VOR is also being displayed (which is how I would fly it in real life), AFAIK, the 430 AFM Supplement has not been updated to reflect that and still says flying a non-GPS approach - any approach without GPS in the title - "is not authorized with GPS navigation guidance." He may know the proclivities of the DPE he is going to send you to. Really - talk to the instructor about it. The DPE might want you to demonstrate flying the VOR approach "old school" - failed GPS - and your instructor is preparing you for that.Yes, you absolutely can use the GPS in pace of DME.There are a couple of things at work here, some more obvious than others.
