bearing fix does have the virtue that the angle of cut is
90°.
However, in such circumstances the respective
accuracies of the two position lines must be borne in
mind.
8.3.2.4 The use of single position lines
A single radar range or bearing can be used in the same
way as any other single position line to exploit the vari-
ous general navigation techniques, such as the running
fix, which maximizes the use of such observations.
8.3.2.5 The combination of
radar
position lines with those
from other
sources
Radar ranges and bearings should be seen as one of
several sources of position lines all of which may be
combined
