Hello all,

Anybody know of an available function in the KLN-89B that shows
'velocity made good?' That is, if you are not flying directly toward a
waypoint, what is the closing velocity? Groundspeed, as reported, is
relative to the velocity vector, so that isn't the correct figure.
Why? you ask. Well, I had a chance to fly a DME arc with a DME. Don't
laugh, it was actually my first experience with DME. The instrument reported
the heading and closing speed. Click, the light came on! When my aircraft's
velocity vector was normal to the waypoint, the speed was zero. For me, that
dropped the workload of flying the arc way, way down. The Skyhawk SP that I
mostly fly ain't got no DME but it does have a KLN-89B. Unfortunately, the
limited user information available says nothing about the feature I'm
looking for.
