Not getting the Glidepath indicator on my HSI

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have an IFD440 installed in my Mooney. I have a Sandel SN3500 HSI and Stec60-2 Autopilot. I had the IFD440 installed late last summer. I am currently working on my Instrument rating and while flying practice approaches last night with my CFII, we noticed that we get the glideslope indicator on the HSI when flying an ILS approach but when flying an LPV approach we do not get the glidepath indicator on the HSI. My previous navigator was a GNS430 (non-WAAS) so I had to have a WAAS antenna installed.
Any idea on why I am missing the glidepath indicator on the HSI when flying a RNAV approach with vertical guidance? Is it a wiring issue or possibly a config issue in the IFD settings? I've already let my avionics shop know about the issue so it will be going in the shop in a few weeks to have it addressed but I'd like to know what to look for ahead of time. If it's a config issue, then I can address that easily enough but if it's a wiring issue then the avionics shop will need to address that. I've download teh IFD Installation manual that describes the various ARINC settings in the IFD config so I am planning on taking a look at those settings this afternoon.

	Check that the Advisory Glideslope is ON in “User Options” in “Aux”-“Setup”. Edited by DH82FLYER - 03 Mar 2021 at 7:42pm
