GTN750 not picking up GS on RNAV/LPV approach (resolved)

I did two RNAV approaches.  One at KBIL RNAV (GPS) Y RWY 28R.  This approach shows GP 3.00 degrees in the approach plate.  NAV worked well during the approach, having to select the altitude restrictions for each leg of the approach, 9000 initially and then 6000, manually descent during the approach.  From  6000 I select APR when turning on the final approach coarse.  The autopilot intercepted the glidepath and decended appropriately.  I then tried the RNAV RWY 10 at SBSV.  I flew the approach the same way I flew the RNAV at KBIL.  On this approach however when at the final approach fix on APR the autopilot did not engage a glide slope.  The aircraft had to be manually descended.  I checked in the GTN 750 for approach plates for SBSV and there were no approach plates available.  I don't know if this has anything to do with the aircraft not intercepting a glide path.  I checked approach plates for SBSV in another source and those indicated a 3.0 degree descent from the FAF but did not indicate a glide path.  So there may not be any and the approach altitudes have to be controlled manually.

Thank you so much! I wonder why the Aerobask Eclipse that use a "Kind of GTN750" integrated does the glide path for SBSV and the Genuine Garmin one does not. May the Aerobask did something "special" that is not on real world thing? Thx Again, so, iam kinda happy that the approach is the problem, not the RXP GTN.

I installed an update (2.5.15.0) today.  It fixed the issue I was having with my Carenado S550 Citation II and Carenado Saab 340.  Thank you!

Hello all. I have read through this entire thread. I noticed one user had issues with the Bonanza F33. NAV mode does not work for me either and RNAV approaches don't capture GS. I am on xplane 11.32r2 and the latest GTN software. I am using the REP version. Thoughts?

And Master Device is GTN 750 #1?

Yes sir. I also turned off the GTN750 plugin off and back on. I also selected master device off and back on. Somtimes when I cycle the CDI from VLOC to GPS it works and NAV ARM goes to NAV CPLD. I have noticed the GPS/NAV PUSH to SWITCH button flashes on and off quickly and the HSI flashes really quick. It does not show the change.

Hi,

please make sure to download and install the latest v2.5.16 just released a few minutes ago and let us know how this one works.

It seems to be working now. The only thing I notice is the GTN750 turns on when I turn on the Alternator prior to the Master Avionics Switch being turned on.

Thank you for the feedback. This is because what used to be the default power source (Avionics On) has changed to 'Automatic'.

Like indicated in the release notes, Automatic uses the same electrical bus as the one the aircraft is using for the default X-Plane GPS. This is a better default for two reasons: most likely the aircraft is already configured with the default GPS in mind, otherwise, the GTN/GNS V2 will be using Bus#1 anyhow, and the 'avionics_on' dataref may tell the plugin it is ON even though there is no current on the buses. (Note: I'm talking about the dataref supposedly indicating whether there is current, not the dataref indicating whether the switch is ON).

You may want to change the Power Source setting and adapt this to your preferences?
