Primary source for Vertical Velocity for the Tracker. If the
data is not on the primary data source (ADS) then the tracker
will look for Vertical Velocity on AHRS bus. If not on the
AHRS bus then will look for label 212 on the ADS bus.
Required for proper Tracker operation. If not present then
the tracker will set the vertical velocity to 0 ft/min. Minor
errors in range (typically less than 0.5 nm) will occur during
aircraft transitions in altitude.
