This time I waited 20 minutes and got someone who didnít know what I was talking about, but this guy was nice enough to allow me to sit in silence for a while (like 10-15 minutes) while he read about it. Dude was very rude, interrupting numerous times and assuring me that he was right and that what I, and others, were experiencing was not correct.
Long story short, I believe we did figure out the issue. When I first signed up for the fly Garmin account, I deleted the old (not current) terrain database off the memory card. Apparently even though the simulated glide slope does not ensure terrain and obstacle clearance, it does require a terrain database, even an outdated and not current one.
I spent the $150 to buy a terrain database and will load it and give it another shot tomorrow. I did not do the obstacle database yet. Hoping I donít have to since I pay for both of those databases already through Seattle avionics for the Dynon skyview.
Latech15, I am sorry you had a less than desirable experience in your interface with Garmin. It sounds like in the end you were able to solve your problem. You may have better results emailing us directly, see email address in the signature below.
The GTN Pilot's guide is quite large, so I understand it can be challenging to sort through the large amount of information. It is often helpful to use the search or find feature to navigate to the relevant section of the document. The Pilot's Guide has the following note:
"NOTE: If the GTN does not have a valid terrain database, advisory vertical guidance is not available for visual approaches".
Based on this note, you should not need an obstacle database and you should now find your feature working as you expected. Please let us know if we can help in any other way.
