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?

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?

I own a Comanche. Where did you get the idea that the GFC500 would be available for the Comanches. I know that STEC is certifying the 3100 but I thought Garmin had dropped the GFC500 on Comanches, or at least pushed it back.

Hello Avidyne,
Any update on GI-275 functionality with the IFD 540? Now I’m seriously considering dual GI-275’s to replace my air driven horizon and King HSI, it would enable me to get rid of the air gyro system (pump, regulator, filter, plumbing, gauge, etc.), have fail over redundancy, internal battery backups, GPSS steering, plus it will drive my Century III autopilot.

What exactly does the GAD 42 do and why is it needed? The usually loquacious Germin web site doesn't give any usable information on the GAD 42. I have a single G5 AI, IFD, and GAD29B but no GAD42. The GAD29B provides the 2-way communication interface between the IFD (ARINC) and the G5 (CAN-bus). The G5 has RS232 input but otherwise needs the CAN-bus which is where the GAD29B comes in.

Remote Selected Course Input ARINC 407 format 3-wire XYZ synchro or 4-wire Sin/Cos
GPS RMI/OBI output ARINC 407 format 3-wire XYZ synchro or 4-wire Sin/Cos
NAV RMI/OBI output (when interfaced with GNS 430/530) ARINC 561 format analog roll steering output for use
with flight control systems ARINC 561/568 distance display on compatible indicators ARINC 561 6-wire interface for Rockwell Collins EHSI 74 & EFIS 85/86
King serial distance display on compatible indicators ARINC 545/KIFIS XYZ synchro or ARINC 565 AC/DC TAS input RS-422 serial data input from Rockwell Collins digital course selector RS-422 serial data NAV/ILS output for Rockwell Collins EFIS 85/86

Thanks. For the most part, that looks like information needed for a G5 as HSI but not AI.

I was looking through the installation for the G5 and the GAD 42, unless I'm reading it wrong according to the G5 installation manual the GAD 42 is Only used with non-WAAS GNS and non-
Garmin Autopilot is interfaced (Garmin's emphasis not mine). I don't see the KFC500 listed in the G5 install manual, maybe that's why the GAD 42 was needed?

Me too. I was told today by an avionics shop that they will not quote a dual GI 275 installation for me because they have no way to get it approved. Not good for Avidyne or Garmin.

I join the group hoping that the GI275 will be added to Avidyne’s STC. I wanted to install the GFC500 autopilot and got this reply from the radio shop. “Unfortunately at this point there is no STC approval to interface the Avidyne IFD's to the GI-275. Functionally the interface will work so I expect it to be added either to the GI-275 STC Installation Manual or the Avidyne IFD STC Installation Manual at some point in the future. There are other Avidyne users interested in GI-275 installation so hopefully sooner than later.” Edited by teeth6 - 08 Apr 2021 at 11:06pm |

Any update on this? I’m still very interesting in getting dual GI-275’s to go with my IFD 540 and still have no STC path from Garmin or Avidyne that will allow the installation. ???

Last I heard, Avidyne was planning to include the GI 275 in their IM but that won’t ne happening until release 10.3.0.2 at the earliest. As we are still waiting on 10.3, I’m guessing it will be sometime in early 2022.

So, why can't a field approval be done? I have a G5 interfaced with my IFD and my aircraft is not on the AML, simply because Garmin mistakenly left it off. They have no plans to update the list.
I would think that as long as the protocols are compatible and the shop certifies that it works, a field approval should suffice. Garmin will never put Avidyne equipment on their STC. They want to push customers to only use their equipment.

I’m sure a field approval could be attempted if someone wanted to go through that exercise. For the G5, it was my understanding it is a legal install as it is already in the Avidyne IM.

in your case, because the G5 is listed in the Avidyne IM, A field approval was not needed even though the IFD is not on the Garmin list. To get a field approval, the local FSDO would have to be involved and since these are primary flight instruments, I suspect flight testing might be done. Once the GI 275 is listed in the Avidyne IM, A field approval will not be needed even though the IFD is still not listed in the Garmin paperwork

I can't speak to the nuances of Field Approvals, STCs, 337s, etc. So, let me ask, do you believe that Avidyne's IM approving the interface between the G5 and the IFD takes precedence over the Garmin STC, which doesn't list my aircraft as approved for installing the G5?

I would not say that it takes precedence but it is certainly equal and makes your installation perfectly legal

Interesting. So, I have a Garmin G5 STC, which doesn't provide approval for installation in my aircraft, but the Avidyne IM makes the installation legal without any additional approvals needed. Not what I would have expected. I don't think my avionics installer would agree with that, which is why I believe he did an additional approval step.
To me, the Avidyne IM provides no information about what aircraft the G5 can legally be installed in, only that it is allowed to be interfaced with an IFD. Then again, I'm not an expert on the approvals and paperwork required.

I apologize. I thought your issue was the G5 being legal to work with the IFDs, which it is because of the Avidyne IM. I didn’t realize you were talking about the G5 being legal in your particular aircraft which, of course, the Avidyne IM has nothing to do with that.

Field approvals are just fine if the local FSDO is willing to do one. A local shop I contacted said the local FSDO is “too busy” and won’t do field approvals.
That’s why I need Garmin or Avidyne to provide an STC or no upgrade will be happening to my panel.

My A&P told me my local FSDO will no longer do field approvals. You must hire and pay a person to go through the process on your behalf. I’m told this person is also an FAA employee but I’ve not confirmed this info

Hopefully Avidyne will add the GI275 to the IFD installation manual. The STC stipulates acceptable avionic interfaces as identified in the IFD installation manual. I believe the GI275 has like five different configurations (ADI, HSI, CDI, MFD, EIS) available. Avidyne will have to purchase some GI275s and integrate them into a system. That will require an upgrade to the firmware and to the documentation. It won't be cheap. Hopefully they have some development money lying around that they can spend on this.
