Maybe so, but the angle seems to compute out closer to the descent angle
from FAWP to stepdown, limited by the precision in the numbers on the chart.

The question remains, though, where does the glideslope begin in the GPS
unit: from the FAWP or from the point 0.1 nm after that waypoint?

Beats me. Have you tried to find out in the Garmin Handbook and
couldn't find it?

Having said that, the advisory vertical path is provided to Garmin, and
other avionics vendors, by Jeppesen.

So, assuming no errors on the part of Jeppesen, it doesn't matter
whether you are using their chart or NACO's.

If my butt were on the line I would be keeping an eye on that stepdown fix.

I guess I would have more confidence with L/VNAV.

I would, however, only have complete confidence in LPV.
