Garmin 175 coupled to Skyview HDX

[LouRubin]

I just started experimenting shooting GPS approaches with a Garmin 175. The first thing I noticed the glideslope didnt activate until the FAF about 5 miles from the runway.
Is this normal ? The second approach the final approach course didnt line up with the runway. I also had no glideslope information. Im wondering if the 175 is having issues or its a communication issue with the Skyview?

The VNAV will become active on the GPS175 on the leg inbound to the FAF. That is normal.

The second approach the final approach course didnt line up with the runway. I also had no glideslope information. Im wondering if the 175 is having issues or its a communication issue with the Skyview?

Well, some approaches do not line up with the runway. Look at the RNAV-04 at KMHV, for example. If you don't tell us which approach it was that you're discussing, it's going to be pretty hard for anyone to guess at whether the system is behaving correctly or not.

And since you don't tell us which approach you were on, it's also hard to know if it would/should have had VNAV displayed - was this an LPV, LNAV, LNAV/VNAV, LP+V or LP approach? Not all have vertical guidance... See:

And folks - as has been mentioned numerous times before, the more information on your situation and configuration you can give when asking a question, the more likely it is that someone will be able to help. "This isn't working" isn't a lot to go on...

This approach definitely aligns with the runway. It a LPV approach Runway 1 Sebring Fl. Im thinking its a glitch with the Gnx 175. Is there any information regarding approaches pertaining the Skyview? I didnt see any information in the Pilots manual. Ive read there has been issues with the 175 communicating with the Skyview from several users.
Whats the normal range for the glideslope to activate?

Using airport Identifiers (KSEF, in this case) would make it a lot easier for folks at home to follow along. So yes - the approach is aligned. What's your definition of "not aligned"? Heading not 005? Track not 005? What were the winds? Are you using a Flight Director? AutoPilot? If the A/P, how does it do wrt holding course in NAV mode? How does it do when using the Dynon flight plan as a navigation source vs. using the GPS 175 as a navigation source when enroute?

Im thinking its a glitch with the Gnx 175

There's no such thing as a Gnx175 - it's a GPS 175 - I've got one in my COZY MKIV. There's nowhere near enough information in your postings to make that assumption. Is the GPS 175 connected to the Dynon Skyview through an ARINC-429 module? Have you checked all the hardware connections to make sure all the pins are connected and clean?

Is there any information regarding approaches pertaining the Skyview?

What does that mean? Assuming you've got the Skyview set to use the GPS 175 as the flight plan guidance, it will follow whatever purple line the GPS 175 gives it, both horizontally and vertically. Do you have the Seattle Avionics plates loaded? If so, what were you seeing on the screen for the KSEF RNAV01 approach.

I didnt see any information in the Pilots manual.

Revision P shows the word "approach" occurring on 20 pages in the PIlot's User Guide.

Whats the normal range for the glideslope to activate?

The VNAV will activate upon reaching the approach segment leading to the FAF, so in this case, upon passing EMBRU on the way to POPMM.

Please don't force people to pull teeth to help you... I'm sure there'll be more questions, but at least answering these will let folks get somewhere near to where you are...

I appreciate everyone’s comments ,however I certainly am not forcing anyone to comment pulling teeth. If you feel that way,please don’t comment and save us both the aggravation.

The GPS 175 is connected with a Ariinc429
I’m not using Seattle charts
The first approach the course was aligned perfectly
The second on it appeared offset 10 degrees . The For some reason I don’t think the GPS locked on to the approach I’ll try it again

MyVnav didn’t activate until POPMM
Hand flown
GPS 175 was selected for the approach
