Glideslope / VNAV Indicator

[rfazio1951]

I'm finally flying my skyview and have been playing around with the screens and setup. Last night I set a course on the map page to a local airport and also set it on my 396. I get the HSI to show bearing from both the Skyview GPS, and from the 396. I couldn't seem to get the glidescope from the 396. Should I be able to get glidescope from a 396? I would think so. It does have that capability itself, and It was showing using waas. I know it's not IFR legal but was just trying it out in VFR conditions. Also how is the glideslope displayed? There is no picture of it in the manual, it just says it is displayed when it gets vertical nav from a GPS. I'm guessing it would be a horizontal line in the HSI that moves up or down indicating direction to follow.

I think I answered my own question. I have to setup a vnav profile in the 396 before it will display, or send out to the skyview, any vnav info.

You need to refresh your understanding of what constitutes a GS or glideslope. It has nothing to do with the vertical descent profile that the 396 generates for descent from cruise altitude to pAttern altitude
Sky view will display a glideslope indicator needle to the side of the HSI when it is fed a signal from your NAV receiver when it is tuned to a LOC frequency.
In addition, when a certified WAAS GPS receiver is flying a LPV approach and your sky view is properly set up, it will display the GS needle after passing the FAF.
The 396/496/aera does not come close to those particular capabilities.

The SV will take the GS indicator from a 396/496 and display it in the HSI. That indicator is reference to the descent profile to the patern altitude (for instance) and I have it displaying just fine on the HSI.

Yes you cant use it for an instrument approach but you certainly can use it for reference as to when to head down from altitude.

That's all I wanted to see. I also was trying it out just to see what it looked like on the HSI. I guess I just need to setup the 396 to show VNAV and I'll see it on the Skyview. Next time I'm out flying I'll try it out. Thanks for the info guys.

The confusion sounds dangerous to me

The x96 units stop showing any vertical guidance when within 1,000 ft of the ground so it is not possible to mistakenly fly it as an ILS glideslope.

If you have an IFR WAAS certified GPS you are not using the 396/496 for vertical guidance. If you don't and you are using the 396/496 for vertical guidance down to pattern altitude, then you know you are not using it for an ILS/GPS approach. Should be no danger if you know your systems and its limitations.
