Has the capability of sending out 1ft resolution altitude
data to either the GPS/Loran and/or AMS-2000. Because a static
input is received, Shadin Avionics' patented recalibration of the gray
code after the first 200 foot change in altitude allows for
10ft increments to be displayed on the GPS or AMS-2000. If used
with the AMS-2000 Instantaneous Vertical Speed (IVS) is calculated,
which allows for a time based warning as you approach
your target altitude.
