Loading LOC/GPS Approaches Into Garmin 430.
Asked by: Edilson Gomes 4305 views FAA Regulations, Instrument Rating
Hello Everyone,
Have you ever noticed that when you load any approach, other than RNAV approach, you get "GPS guidance is for monitoring only. Load approach?" message?
I was under the impression that you could still legally load a localizer approach to use the along track distance (ATD) readout per AIM 1-2-3, GPS in lieu of DME.
However, recently I was told that you can't do that because you are using the distance of a non RNAV approach past the FAF. I was pointed to the Garmin manual which states:
The navigation equipment required to join and fly an instrument
approach procedure is indicated by the title of the procedure and
notes on the IAP chart. Navigating the final approach segment (that
segment from the final approach fix to the missed approach point) of
an ILS, LOC, LOC-BC, LDA, SDF, MLS, VOR, TACAN approach,
or any other type of approach not approved for GPS, is not authorized
with GPS navigation guidance. GPS guidance can only be used for
approach procedures with GPS or RNAV in the procedure title. ( Page 10 of the Garmin manual-190-00356-03)
Since on a localizer approach does not have RNAV or GPS in the title you would have to use the Direct-to function and use I-PYM, for example, to get the proper and legal DME distance.
What are your thoughts? Is the “guidance” part of the statement meant for course only or also DME/fixes?
