Glide slope not showing up

[Zbot]

Flying an RNAV/GPS approach with the MU-2 does anyone know how to get the glide slope to show up? The CDI shows the lateral path fine, but not the vertical path.

My understanding is the AP won’t follow it unless it’s on an ILS, but I would still expect VNAV guidance.

thanks!

It does but it depends on your Settings.
I'm not a Pilot so some steps may be not in the correct way.
When following a Flight Plane (loaded and active in the Garmin), my AP is set to ALT, HDG and the GPS/HDG Switch is set to GPS. CDI in the Garmin is also set to GPS. The Plane is now following the magenta Line with GPS Support.
When in Range, Localizer/ILS Frequency at the arrival Airport is set on NAV1.
You know your Arrival Runway and load the RNAV/GPS approach in the Garmin. Close enough to the Airport, you activate the approach. The Plane is now following the approach Procedure. If you see the Localizer ID in the Garmin, switch the CDI from GPS to VNAV. You will now have Localizer and Glide Path Support but the Plane is not following the Glide Slope until you hit APR on the AP. You have to decent at your own.
And the ILS System at the Airport must support Glide Path.

Thanks, I’m familiar with changing the CDI selection to VLOC for an ILS, but here I’m talking about a GPS/RNAV approach just showing on the CDI, not even autopilot.

Ah, Hand flying the Approach. That did work too, just did it on my Home Airport, EDDG, RWY 25.
The Moo with the Classic Six Pack Cockpit.
NAV1 is set to the ILS/LOC Freq for RWY 25.
RNAV/GPS Approach (RNV25 GPS, OSNAD IAF) is loaded into the Garmin 530.
CDI set to VLOC.
OBS Course on the HSI is set for the RWY (250).
No Autopilot active.
Flying the Approach by Hand.
As soon as the Localizer ID is shown in the Garmin, the Localizer Indicator or Course Deviation Indicator becomes active and shows the Deviation to the Runway.
When you are in Range for the Glideslope, the Glideslope Deviation Indicator becomes active in both Instruments, the HSI and the Attitude Director Indicator. The Vertical Path is shown with the small red Bars on the right Side of both Instruments. Now you can follow the Glideslope manually. 

I think you know, when flying a RNAV/GPS Approach with active Autopilot, there is no Glideslope following. Only Heading.
