Substituting non-IFR GPS for DME

[tree96]

Perhaps; perhaps not. My group posed that very question to the FAA several weeks ago. The preliminary response was that they had not thought of that. But, a definitive answer may be a long time coming. In the meantime, as a Part 91 operator, I would do as you propose. Those fixes on the moving map are indeed correct assuming a current database and a reasonable map scale.

Yes a current database and in the proper scale.

Other things I have read made it sound like I needed to do direct to for each fix on the approach. I dunno

I don't understand why that wouldn't fall under the AIM provision that allows an IFR GPS to substitute for DME.

so with a 430, load and activate the approach then flying past the VOR will the dme fixes on the moving map be correct? I know the cdi VOR head needs to be the primary nav source, the aim or my lack of reading comprehension made it fuzzy for me...

My AFM has a limitation stating "The map mode ... On the MFD are provided only as an aid and are not approved as primary information."

Not a 430, but maybe it's got something similar.

That's why my group posed the question. It seems they have no ready answer. So far, I doubt it is approved for any moving map.
