Garmin Guided Visual Approaches?

[Rick Junkin]

Has anyone used these or know anything more about them? These are different than the visual runway guidance that had been previously available. It's a $200 premium on top of the normal nav database, and according to this video there are only 30 some airports for which Garmin has developed these "approaches".

WAG: the 30 airports are the only 30 airports which need it. The clue for me is that they're using Aspen as the example. If you look at the instrument approaches at Aspen, the MDAs are over 2,000 AGL (not MSL) . There is no vertical guidance for the rest of the way down. And I think this is what these new approach types are an attempt to do - provide some level of visual guidance with target altitudes for a stabilized approach in these situations. I suspect the value will be to those pilots who fly into those types of airports.

I understand there are lot of these that are generated on-the-fly and used behind scenes for "auto-land" equipped aircraft, they support 3D path and you get en-route NAV with en-route VNAV followed by LNAV+V on short final, including to non-precision runways ! 

Obviously, for auto-land the algorithm is more likely to stay out of challenging places like Aspen or Bravo airports  

The "Visual Approch" are generated on-the-fly and checked against database obstacles otherwise you don't get +V 

It seems "Visual Guided Approch" are somehow pre-coded in database (rather than generated on-the-fly), maybe they involve some quality checks or flight validation? I hope people understand that these need  visual approach conditions?

The naming convention are confusing, it's awful: they look like proper plates GPS RNP procedures, except "G" being added? I wonder what kind of checks are done on glide from "Visual Guided App" against airspace or terrain? and if some of the segments implement "radius to fix" legs? does "Visual Guided App" require up to date terrain and obstacle database? or valid terrain and obstacles data?
