1.39 Set and Drift
(Set and Rate)
Set the direction in which a water current
flos, can be manually entered in 0.1 - de-
gree steps. Drift, in another word Rate,
the speed of tide, can also be entered
manually in 0.1 knot steps.
Set and drift corrections are benefcal for
increasing the accuracy of vectors and
target data. The correction is best made
in the head-up mode with true vector,
watching landmasses, or other
stationarytargets. If they have vectors, set
and drift values should be adjusted until
they lose vectors.
