Final glide

I do agree about the desire to have a "reserve" for graphical purposes. I believe clear nav can show the landing amobia both with and without reserve.. I wish the Lx would do this as well. I could cheat this in XCSoar with a terrain clearance. So the marginally reachable did not appear to be reachable with a 1000ft terrain clearance. But the best solution is a reserve that is only applied to the map view. This becomes a quick visual filter, only show me landing spots where I have the altitude for a decent approach. For me, the advantage of having an accurate arrival height is better than the inconvenience of checking if a candidate field has the margin I want. You only really get that after you have pick to go there anyway.

In Tophat the moving map shows the arrival altitude next to each landable waypoint that is within glide range. I use that instead of the color to identify the ones within range. (No colors on the Nook anyway :-)
And since, like Evan, I set the reserve altitude to zero, I do see some arrival altitudes on the map that are really too low to be safe, e.g., 300 feet. That's still good for planning, though, since it tells me that if I were to get a little higher, or closer, that landing spot will become a safer bet.
