Could someone explain how to use the L/D feature,
in cruise, on my L-Nav. What should I do when it
show a L/D of 99...etc?

I have tried looking at it a few times on final glide and to tell you the
truth, I think it is completely useless information. In the first place, it
doesn't stay steady, does it? Hit a bump and it says we are doing 99:1, hit
some sink and is says we are doing 20:1. Just what can I do with this
information? I watch the "altitude required" and rate its change. That is to
say, if the altitude required to make the glide, is increasing slowly, then I
am doing better than expected and might thinking about increasing my MacCready
setting (speed up, some) On the other hand, if the "altitude required" is
decreasing, we got big trouble, right here in River City. We need to slow down
by decreasing the macCready setting and we may want to take the next lift that
presents itself.
