How to get distance to LOC with a Garmin430

Asked by: 3759 views , ,
Airspace, Flight Instructor, Instrument Rating

I use the G430 in lieu of DME (IFR approved GPS w/current database), but I cannot figure out how to get distance to a Localizer navaid. More specifically, an instrument approach that requires "DME" (and I will use G430), but the distances are based off of the localizer. Not sure how to get this distance since the navaid doesn't show up in the list of options in the G430 database. Specifically the ILS35 at KGXY wants DME off of I-DCI (the localizer). How can I get this in the G430 (the distances also don't show up if I program the ILS approach (for reference SA)). (I know I only need the DME if a LOC only approach, but I still have my question). Thanks

    IDCI is in the database. Tune your avionics the old fashioned way to get your localizer guidance if you only have one GNS430. Program IDCI into your GNS430 and use the direct-to button to activate your route. Display the distance on your GPS. If you have two GNS430 systems, load the approach on one and on the other use the direct-to IDCI to get your distance.

    Better yet, avoid this foolishness and fly the RNAV 35 rather than the LOC/DME portion. It has a lower MDA and you don’t have any issues with DME.

    If you load/activate the procedure from the database, the fixes (like ARTSS, or the MAP at the runway threshold) should show up with the distances to them.

    But to answer your direct question, if you just wanted it to show the distance to the actual DME source (in this case collocated with the LOC antenna), do “Direct” to the localizer identifier, IDCI (without the hyphen). This should work with any localizer.

    Russ,

    ARTSS won’t show up as a named fix on the ILS approach. Generally, stepdown fixes are omitted in the database for an ILS procedure.

    Thanks John. I’m sure you’re right, I answered too quickly. It has been a while since I have flown (or taught) a Localizer (that had a ILS as well), with stepdown fixes, loaded from the 430 database. (That’s my excuse.)

    It looks like we simul-posted the IDCI answer (not that we can tell on this board).

    Well my mistake was not entering IDCI correctly. This question is because I didn’t enter it correctly. Yes IDCI is happily in my database and thanks for the answers that supported what I had expected. I will inter IDCI 100 times on the chalk board. Thanks all. (and the purpose was for training purposes)
