So you also have a GAD29B to convert ARINC429 to the CAN bus for connection to the G5, correct? The G5 only has RS232 and CAN bus connections, no ARINC429.

Just a follow-up here.  I now have a fully functioning G5 / GFC500/ IFD540 installation.  Everything works as it should with no error messages.  I'm using the EFIS/Airdata ARINC429 data stream, not the GAD 42.

Two notes:

1) As others have mentioned, the VNAV function on the autopilot does not work.  It does not work on a GNS530/430 either and only works with the GTN series navigators where it has a digital data stream.  This was expected.

2) When the IFD annunciates GPS --> LPV or LP or LNAV or LNAV/VNAV, the G5 annunciates LPV.  Technically the IFD is still in TERM or ENR mode, so the annunciation is not correct.

Are you getting the GAD42 error?

Would you be willing to send me screen shots of your G5 and IFD ARINC and RS232 settings and the status of your GPSS Roll steering - is it enabled or disabled?

Interesting that you are going through these issues. I had dual G5's and a GFC 500 connected to my already installed single IFD540 last fall and did not experience these RNAV approach issues. My IFD540 was running s/w 10.2.4.1 and the G5's were using certified G5 software 6.72 at install. The respective software versions are now at 10.2.6.1 and 6.82 with no observable changes in behavior. The install between the IFD540 and the G5's was right out of the Avidyne IFD IM with no splicing to bypass the GAD29B required.

Any help you can give would be great.

My installation of dual G5’s and the GFC500 autopilot connected to my already installed dual IFD540 is nearing completion.  On the flight checkout, all of the GFC500 functions work correctly except for RNAV approaches.  Just before the FAF when the IFD does it’s GPS precision calculation and the IFD changes from GPS to LPV or LP, the GFC500 kicks out of APPR mode and will not reengage. I am approaching the glide path from below and the G5’s show both vertical and lateral deviation and I can hand fly to minimums. The GFC500 will fly an ILS fully coupled with no issues.

I'll have to check with the customer on the approach mode and see if he lost that as I don't remember him mentioning that.  Yes, I've seen the diagram for splicing the 429 to bypass the GAD unit.   I'll have to review my notes on that and see if we had to do that at all.

I’ve never heard about this. What do you mean by splicing the ARINC429 to bypass the GAD29B. I don’t think we did that.  Where can I get the splicing information and diagram?

Any suggestions would be great.

Gring, it appears the issue is with the GI275 with the GFC500 and IFDs.   I got this from the same shop you went to (I did not mention you at all) but the GFC500 would not be a legal installation in my plane with the GI275.  The other reply is from a separate shop. They are in agreement that the IFDs with the GI275 is not a legal install with the GFC500. 

<<
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.>>

<< Unfortunately, you are correct.  No field approvals on Autopilots.  You’d have to replace one of the IFDs with a GARMIN GTNx50 or legacy GNSx30W.>>

I don’t have a copy but copied below was the discussion on my user group concerning the use of a GI275 which was a legal install.  With that being said, it sure seems like many shops are installing the GFC500 with planes having the IFDs and GI275s or G5’s.  I guess the shops don’t see an issue with it. Can someone confirm that we would lose the VNAV function if switching to the GFC500?


<<<The GFC500 STC requires that the attitude source (GI-275) used by the GFC500 be installed in accordance with the GI-275 STC. That calls out a Garmin GPS. Once you add a non-Garmin GPS into the mix the GI-275 is no longer installed in accordance with the Garmin STC (its installed in accordance with the field approval).

This means a "follow-on" approval based on an existing GI-275 installation (even if that specific installation was correctly field approved) will not fly in my view (and I believe the view of the FAA).

Avidyne will need to resolve this since the FAA does not typically accept field approvals involving autopilot installations (I'm not aware of a single case where they have outside of the warbird world).

The only way I see for this (GFC500 installation with an Avidyne GPS) to be legal is for Avidyne to do the work to add the GFC500 and the GI-275 to their STC. I don't believe the "well it (the IFD540) emulates a 530" will fly in this case.>>>

My PA32 with dual G5's and an IFD550 is in the shop right now for the GFC500. Also installing the GAD 13 for TAS and OAT.

Kinda disappointed that VNAV control via the GFC500 isn't available with this combo but I'm still happy with the upgrade.

Do you have a copy of that statement? I can't find anywhere in the GFC500 STC that mentions a GPS let alone that it must be a Garmin GPS. I just see the concurrent requirement for G5 or G3X STCs. However, the STC published on the FAA web site might be out of date, since it also doesn't mention the GI275.

Agree with you on the GI275s.  Technically, they use the same input/output data streams as the G5, however, the Install Manual on either side has not been updated to include each other's interfaces.

Here is where Avidyne can help by adding the various PFDs to the installation manual as well as the G500 autopilot.  As long as there is not an Avidyne solution (PFD and Autopilot), there needs to be a way to use commonly available equipment in the market.  It seems, either you are an all in one (Garmin) company, or a company that is built around successful interfaces to 3rd party equipment.  You have to be one or the other to be successful.

I don’t know why this is so difficult with the G5 since it is fully supported by the Avidyne install manual as a listed interface.  The G5 is the autopilot “brains” and uses standard communication data streams.  Further, since the IFDs are a direct replacement for the GNS navigators there is legal basis for it to work with the GFC500 autopilot.

I’m using a new shop this time - Green Mountain Avionics in Middlebury VT (6B0). I really like the time and care they have taken to work through the details.

it’s so strange there are differing viewpoints.  I’d really like to put in the GFC500 as it was just STCd for the Trinidad’s but our user group and Avidyne is saying “no way” with Avidyne GPS. What shop did you use? I’m pretty sure we have used the same shop in the past? You can message me if you’d rather not post it.

I’m in the process of a dual G5 and GFC500 autopilot in my Bonanza. The install shop discussed my options - G5, GI275, G3X, and G500txi and had no issue installing any of them. In the end, I went with simple as I’m still hopeful Avidyne will produce a PFD.

I am not sure of the G5 but according to Avidyne if the combo is an IFD with the GI275, then the GFC500 would not be a legal installation.  The GI275 specifically requires a Garmin GPS source and the internal one is advisory only and doesn’t quality.  Avidyne says the argument that if A works with B and B works with C then A and C are legal doesn’t work.  This is the reply I got from Avidyne on the Gi275, IFD and GFC 500 combo. 

<<< The GI-275 is not listed in our IM. I am unable to track down an IM for the GI-275 and I looked at MooneySpace.com and Beechtalk both came up empty. As for getting a field approval for an autopilot installation I have doubts that most FSDO inspectors are capable or confident enough to do so. If in fact the GI-275 STC requires a Garmin GPS source I don't see a way clear that an installer could provide documentation to support a field approval for the GI275, Avidyne IFD, GFC500 combo.>>>

Following an in-depth conversation with Avidyne tech just now - if you (or the shop that says the installation of a GFC 500 isn't approved) follow the paperwork already in existence and approved, the GFC 500 with Dual G5s and an Avidyne IFD is legal. Remember that the IFD is an approved feature-for-feature slide in replacement for a 430/530 which is already approved as a device capable and approved of working with the GFC 500. 

The logic is "If A works with B, and B works with C, then A works with C". Since the Avidyne works with the G5 and is approved for that in Avidyne's documentation, and since ALL the autopilot control comes from the G5 because it processes the signals from the navigator (whether it is a Garmin or Avidyne), then the addition of a GFC 500 is approved since it doesn't need any interfacing with the Avidyne itself. Everything is processed with Garmin devices - G5, GAD29 or 29B, GMU, etc., etc.

I can tell you that my Avidyne 540, dual G5s, GFC500, OAT probe system performs flawlessly - and has for nearly a year performing all the approaches and features as it is supposed to. VNAV is not part of this package - the GNS 430/530 did not provide that data stream originally, so the IFD was not made to do that, either. To add that feature via the IFDs would require additional FAA approval.

It works well for my dual G5, GFC 500, IFD540 equipped airplane. When activated airborne, the go around button puts the flight director and autopilot, if engaged, in the go around mode and annunciates GA for both roll (wings level) and pitch (7 degrees nose up in my airplane). When activated on the ground, the go around button puts the flight director in takeoff mode and annunciates TO for both roll (wings level) and pitch (7 degrees nose up in my airplane). 

Aircraft specific specs and procedures for GFC 500 approved aircraft can be found in the aircraft specific GFC 500 Flight Manual Supplement; downloadable on the Garmin website.

i already instilled Gamin G5 HSI last year, changing it to Dynon Skyview HDX requires D10. I know Dynon is working to get their autopilot certified for Mooney but GFC 500 is what i want to go with. I know Dynon DHX is cheaper vs G3X.

Full GFC 500 functionality would certainly be achieved paired with a Garmin GTN 650 or 750. 

I now have dual G5’s, GFC 500, & IFD540 in my plane. I am very happy with the results; the only nuisance message is a “GAD 42 needs service” message as reported by several forum members with the same setup. As expected, the IFD does not currently send VNAV commands for VNAV climbs or descents. As far as GPS LPV approaches go, my GFC 500 is generally down the centerline. The farthest off centerline I have experienced is lined up with the runway edge lights on a 100’ wide runway inside the FAF...certainly not one or two dots off. 

I haven’t fully tested the autopilot-off ESP functionality yet; however, it should be identical to the Garmin GNS functionality as neither currently pass AGL info to the G5’s.

Have you contacted Garmin to find out why their autopilot won't work fully with the IFD540?
Have you considered the Dynon suite instead of the Garmin suite? You'll definitely get better integration with the IFD.

[Edit:] And you'll likely have better situational awareness and user experience for less money.

In case you don't lurk all messages on this forum, my Cardinal C177b installation of IFD 540, dual G5, and now GFC 500 all work perfectly in all phases of operation and on all approach configurations. The underspeed function works by audible alert if AP is engaged, and by subtle control input if the AP is not engaged. The GFC 500 will 'assist' with press of LVL button, and with pitch and roll inputs when limits are exceeded unless the GFC's breaker is pulled - in other words, it is always standing by to recover from unusual attitude. 

Yes, the GAD message appears and stays in Alerts, but means nothing since I have no GAD 42 installed. Avidyne is working on this spurious message. Similarly, Avidyne is working on enabling VNAV function of GFC 500 coupled with IFD's. Since the 530/430 units don't have VNAV communications, the code of the VNAV data string isn't made public by Garmin, some engineering is needed to figure out how (if) this can be done with IFD where the data is available.

Being able to use Go Around for both takeoff pitch and roll control and for actual go around maneuver is particularly nice in a small single-engine aircraft.

Good morning and thank you for your reply.  I can change the Quote to the 7” G3X screen. However, the G3X is not approved for use with Avidyne IFD Navigators and Avidyne hasn’t done any mods to their units/manuals that specifies that it is approved. Frankly, they just got their approval to use G5’s with IFD navigators last fall and it hasn’t gone well.  We’ve done two such installs and they both had significant issues with the units talking to each other. Avidynes final solution was slow down the data rate between the two, which is working-but not ideal.

Approvals?

That avionics stop statement is a bit lacking in details and while it implies that the problem lay with the IFD, I'm not convinced. I've had a G5 AI installed with my IFD540 for over a year and it worked just fine from the get go. Nothing at all "less than ideal". If I were you, I'd ask them to document the config that didn't work and the one that did.

could you elaborate on what G5/IFD approval your shop was referring to? There is a lot of interest in this subject.

Have one G5 with GFC500 and IFD540 installed in November of last year. No operational issues or error messages.

I installed dual G5, GFC500 and a 540 in my C182Q about six months ago and as previously stated, a GAD message appears but it’s of no consequence.  Everything has been operating appropriately.  Nice system.

Does anyone has a G5, GFC500, IFD540/440/550 combination that works properly under all conditions (ILS/VOR/RNAV) with no error messages or unique procedures to get around a limitation?

Did you have any problems with lpv approaches in youinstallationi? We are struggling to get our GFC 500 and G5 to talk nice with the ifd to fly to minimums. Believe it has to do with the efis information totheifd

Just finished (May 29) updating my Cardinal's dual G5's and IFD 540 to add the GFC 500. Only one issue came up - capturing the VOR CDI by the autopilot. A change to the 429 setting to "GAD 42" solved that capture issue, but now an alert says the (nonexistent) GAD 42 needs servicing. All approaches tested so far work perfectly. Shot an actual to 500' yesterday.

This is where you will want to disable it.

Could you explain the dynamics that are going on with this setting and the need to configure it properly?  Thanks.


At the FAF, the IFD will switch from GPS track deviation commands to roll steering commands, if Appr Roll Steering is ENABLED. What happened to me was that my autopilot suddenly veered to the right at the FAF on an RNAV GPS LP+V approach. Had to CWS back on to the approach course. Apparently, the A/P needs GPS deviation left/right data all the way down.

This only seems to affect digital autopilots, from what I can tell. AviSteve could clarify my misconceptions.
Thanks, but looking for something more technical about why the difference is needed for some applications and what dynamically is going on.  Anyone?

EDIT:  the above is incorrect: the event described above was apparently due to turbulence experienced at that moment. The A/P needs Appr Roll Steering ENABLED in order to couple in approach mode.

I'll have to check with the customer on the approach mode and see if he lost that as I don't remember him mentioning that.   
Yes, I've seen the diagram for splicing the 429 to bypass the GAD unit.   I'll have to review my notes on that and see if we had to do that at all.

we did try to disable the gpss appr but lost the ability to turn appr on the GFC 500. How did you over come that. Currently we are adding the spliced 429 input to the ifd as if it was a 3rd party auto pilot using had 42 and efis airdata both. 

Any help you can give would be great.

Programmer@pcmforles 

I have a install that is having problems with the GPS appr  not being accurate to minimums. The setup is the same as you have discribed IFD540 dual g5, and gfc 500. What was your arinic 429 set to ? I have a feeling avidynes information may be inadequate. Unless you had no issues I would love to hear how your install went. 

Thanks.

I have dual G5's, IFD440, GTX345, PS 450A audio panel and an Stec 50 AP. All works perfectly together! I did have a FastStack wiring harness built for my system when I had the G5 hsi and PS 450A installed, that's the way to go! They know how to get everything "talking" and it saves the shop a bunch of time.

I have a G5 that was installed last June as an AI, along with a GAD29B and GMU11, connected to my IFD540 (per G5 installation instructions to work with a GNS530). I also have a Sandel SN3500. All are interconnected via Arinc 429 and work just fine. Don't know what issues your shop has had.

Comments on this reply I got from an avionics shop in response to my Request for Quote? I currently have an IFD540.


Good morning and thank you for your reply.  I can change the Quote to the 7” G3X screen. However, the G3X is not approved for use with Avidyne IFD Navigators and Avidyne hasn’t done any mods to their units/manuals that specifies that it is approved. Frankly, they just got their approval to use G5’s with IFD navigators last fall and it hasn’t gone well.  We’ve done two such installs and they both had significant issues with the units talking to each other. Avidynes final solution was slow down the data rate between the two, which is working-but not ideal.
