DME on the G1000

[adk]

If you have a bearing pointer on the G1000 set to a VOR, it gives you DME information. Is this real DME or is it GPS based? I can't find anything about it in the G1000 cockpit guide.

When crossing the fix, does it read zero?

I'm nearly positive it's GPS based.

Dme gets its own special box in the g1000 assuming your g1000 is so equipped. Can't find a picture showing the dme box online right now but if you dig in the g1000 manual you should see it. But the default distance readout with a bearing pointer is gps based.

Never thought about that. I would assume it would have to be GPS based since everything on the G1000 is integrated with GPS. With all that equipment, it's hard to see why it wouldn't be.

semihijack: If it is indeed a GPS, can you use that in lieu of a DME above 24k?

So if a G1000 equipped aircraft has true DME it will have a separate DME unit on the panel? I know when you throw an ADF in with a G1000 the ADF is off to the side.

Yes, you get another box that pops up on the side of the HSI. There's also a soft key that lets you select Nav 1, Nav 2, or DME Hold. And yes, you can use GPS in lieu of DME above 24,000.

The DME box is just above the "NAV 1 source". As stated above, that's true DME, and a separate system in the aircraft, unlike the "DME" from the GPS.

That was in the DA42.

That clears it up. I was thinking that DME was an entirely separate "box" just like an ADF is when installed with the G1000.

Yes, you'll have a softkey that says "DME/ADF" on the PFD.

Thank you, that picture is what I was trying (unsuccessfully) to convey with my previous post.

The best way to tell (without looking at supporting materials/POH/etc.) is to simply hit the DME button on the audio panel and see if you get an IDENT. You won't on most aircraft as the system just publishes GPS derived distance.
