HDX Suite + Garmin GPS175: RNP or RNAV only?

[#74430]

Hi Guys,

So I'm running a full Dynon HDX suite with ARINC429 incorporating a Garmin 175 WAAS Navigator. I'm happy that I can use it fly RNAV approaches with lateral guidance, but can it also provide vertical guidance? Or is this only available if it is fed with BARO data?

I've loaded the latest NAVDATA into the GPS175 and can't see any RNP approaches listed. Seem to restrict them all to be RNAV only. Can I overcome this or is this the best I'll be able to achieve with this kit?

Happy to discuss if someone has time to call. Sorry if this is a noob question.

Many thanks,

Dan

Yes. This is my setup as well, and it works perfectly. You need to set up both systems correctly (and it was 5 years ago, so I don't recall what the set ups were), but as long as they are set up right, it works.

So the auto-pilot will physically fly the vertical profile?

Yes. Obviously, I need to manage the throttle so as to maintain appropriate IAS, but the AP will follow the RNAV glideslope.
