More functionality is coming out of the GI275, including ability to drive the GFC500 autopilots.

I was told unequivocally that the IFD series are not on the approved navigator list.

Are there any plans to address this?  Unknown to me if that is something that Avi can do or G* has to do?

I’ve considered this as a way to rid myself of a vacuum system. I understand the GI-275 will drive a 400B but it’s going to have to do it with an IFD540 if it goes in my panel. Any chance a new PFD/MFD be on the horizon from the elfs in the back room in Melbourne?

Thread drift ....

One way to get rid of the vacuum system is to install an uAvionix AV-30 (STC pending, paperwork with FAA). From their web site:
"We are asking for approval to utilize the AV-30 as a stand-alone attitude indicator, attitude indicator and directional gyro (dual unit installation), installation as a replacement for the turn coordinator (leaving the existing attitude indicator in place), and as the required backup in an EFIS installation.

If the installation configuration leaves no instruments that require a vacuum source, the vacuum pump system may be removed from the aircraft via a 337 field alteration process. The removal of the vacuum system is not included in the AV-30-C STC approval."

... would likely cost about the same as replacing a TC should it fail.

Back to original question.

Will the IFD get included as approve nav source for the GI275?

I'm assuming that the "approved navigator list" that you're referencing is in the Garmin Installation Manual.  If so, Avidyne has no control over that list.

The GI275 is obviously new, so it is not included in our STC.  Our STC does get updated from time to time.  Whether a particular piece of equipment is referenced in the STC is based on several factors including market demand, equipment availability, value proposition, manpower, etc.  Whether the GI275 will be included in the next STC update, whenever that might be, is yet to be determined.

Thanks, my suspicion is that it is the same interface as the G5, and one would expect a lot of GI275s will be sold now that it supports the GFC500. 

So please add it to your list.

Thanks!

As a Century III owner (mine still works great) I’m very interested in an upgrade path that allows me to retain the C-III.

If the new GI-275 doesn’t play nicely with my IFD 540 that would be a big problem (for me).

I am very keen to have 2 GI 275's and GFC 500 interface with my IFD 540, as it seems to be the most complete solution, and will be available for Comanches soon.
I am unhappy to see that the lack of height above ground info from the IFD 540 prevents GFC 500 underspeed protection etc from working. 
I hope Avidyne is able to remedy these issues soon, as I don't want to have to go to a Garmin Navigator instead of my IFD 540.
Thanks to the contributors of this forum for bringing these issues to light, as I was unaware of them.
Regards
Jeff

The IFD 540 nor the 440 are approved as the GPS source/navigator on G*’s installation manual nor the IFD 540/440 installation approved interface equipment list from Avidyne for either the G5 Attitude Indicator nor the GFC500. Many long discussions on this site about including this very popular component but it has never been included.  So I doubt the GI275 would be any different.  It does have the GAD 42 Nav interface on Avidyne’s approved equipment list.

so far “crickets” on this issue. I wish I had read all of this website before we installed our G5/GFC500 with our two IFD540’s. We are working diligently with our installation shop to find a solution.

What exactly is the problem? The GFC500 supports GNS devices in the STC, and the Avidyne can be installed as a compatible replacement for that. GNS connection to a G5 AI also needs a GAD29B, and as mentioned above, that is also supported by the IFD.

I have a G5/GAD29B/IFD540 installed for over a year and am considering replacing my STEC30 with the GFC500, so I'm interested in hearing of roadblocks to that route.

There is even a video on youtube from Avi tech support (TJ) outlining the connection between the IFD and the G5.

I installed 2G5’s,  GAD42, a KFC500 already having an IFD 540 in my Cessna 182.  Everything works perfectly and I couldn’t be happier.

Did you mean a GFC500 vs KFC500? If so, did you have a GAD 42 installed as well as a GAD 29B?

yes, a typo.  It is a GFC500 and I believe I have both the GAD42 and the GAD 29B.....but I’ll check to confirm the GAD 29 B

Interesting, do you know where the GAD 42 is wired into the system (i.e. between the IFD540 and the GAD 29B)? Were both the GAD 42 and GAD 29B added to your airplane during the G5 and/or GFC 500 install?
