Avoidance points screen
The
AVOIDANCE POINTS
screen lists all your stored, named
avoidance points by radius; name; distance and bearing; and
lat/lon or TDs (the distance and bearing fields are completely
blank if there’s no position fix). Until you store user-defined
avoidance points in the database, the
AVOIDANCE POINTS
screen will be completely blank.
An avoidance point is
a specific position
defined by its radius,
and either its lat/lon
and TDs, or distance
and bearing
from
some position fix
.
