Has anyone else had issues where the 430W boxes both show LPV but have not been able to get GS on the Avidyne EX5000 Entegra PFD? I am having issues getting the GS command bars to come in on the PFD, despite in all instances having the LOC showing on the HSI and under the attitude indicator.
Quick recap - in GPS mode (not VLOC) for RNAV (GPS) approaches, showing "Term" then converts to "LPV" on both of my 430W boxes. I am getting lateral navigation no problem on GPS approaches but not receiving any glideslope despite having both 430W's showing LPV and displaying a MSG of "approaching VNAV Waypoint" once w/in 2nm of FAF. I've spent hours on phone with Garmin - they say it's an Avidyne issue... Not sure if anyone else has experienced this? I'm trying to diagnose what the potential problem would be. NavData between Garmins and Avidyne are both up to date so not sure what the issue could be on the data/software side. This is a new issue that's come-up recently... |

What software revision do you have on the PFD?

Check the configuration on the #1 GNS430W Before turning on the Avionic Power, press and hold the ENT key then turn the power on. Release the ENT key when the display activates. After the Data Base and Instrument Panel Self-test pages, the first page displayed is the MAIN ARINC 429 CONFIG page. Check that you have the following settings: SDI should show LNAV 1 VNAV should show Enable Labels Repeat the same on the #2 GNS430, SDI should show LNAV 2 VNAV should show Enable Labels |

Tell me the address to send you an Amazon gift certificate... you sir (or madam) are a saint. The fix below did indeed work. I am getting vertical guidance now as expected and my 55X is coupling with the GS and flying the full approach. I'd like to point out that I spent nearly 1 hour on the phone with Garmin's technical support and they didn't know where to start... kept saying it was an Avidyne issue. Then I talked to Avidyne's support - they said it has to be a software issue, couldn't diagnose it... said it probably needed to go to an avionics dealer / mx shop to fix the issue. That is until I got your response which worked wonders. Thank you thank you thank you!!! I'm now officially a believer in forums

Try Honeywell EFIS instead of Sandel on the IN 1. What software version do you have on the PFD?

rev 7 should support LPV, was it working before and now no longer does?
Are all the NAV databases up to date on the GNS 430’s Try to change the GNS setting to Honeywell EFIS instead of Sandel Hope that works Ibrahim

I don’t know if it was working before, because GPS approaches are starting to be published in Portugal!
All NAV databases are current except obstacles! Do I need to update those also?! I’ll try to change the GNS Setting to see if it works, and come back to you.

Do you mean Terrain database, I believe NAV databases include obstacles.
Which airport/runway were you doing the approach into, does it have a published GPS/RNAV with LPV?

No, Jepp publishes Obstacles as a separate database (read "subscription") unless you have subscribed to a complete package of Navdata, Obstacles, Terrain, Charts. But the obstacle database should play no role in this issue.

Is your problem the same one as the original poster? That is, are you seeing LPV annotated on your 430W, but not seeing vertical guidance? If you aren’t seeing LPV, or LNAV+V, you won’t get vertical cues.
The reasons for this are potentially many. The approach may not be in the database, it may not be correct from Jepp, or you may not be receiving the appropriate signals from the SBAS satellite in Europe. |

I didn't try yet this new solution, but still not having before changing EFIS setting.
Where should I see LPV or LNAV+V?

Hi Ibraham Still not getting LPV...In the SBAS selection page I have this: and in a friend of mine plane, I get this: Do you think this can be the problem? How do I get EGNOS option available. These are the versions of my GNS 430: Thank you for your help.
