7.1.6.1 Heading Vectors
1. Heading Vector − True Heading, black in color, which displays the ship’s
heading received from the gyro. You may select to the vector drawn to
the edge of the screen or by length.
Length is based on your speed and selected vector time
(default 6 minutes but up to a maximum of 60 minutes).
2. Course Vector − Course Made Good, orange in color, which displays the
ship’s course made good (from the GPS).
You may select the vector drawn to the edge of the screen or by length
based on your speed and selected vector time (default 6 minutes but
up to a maximum of 60 minutes).
The searchlight scans ahead of the ship looking for restricted zones (Based on
chart and ship information). The time interval, the searchlight looks ahead, is de-
termined by the length of the heading vector. The width is determined by the
cross track error alarm distance. Please see
Cross − Track Error Alarm ,
chapter
8.2.16.
NOTE
The length of your own ship heading vector also determines the length
of the heading vector for ARPA targets.
