VECTOR TIME
The Vector Time label (Figure 5.5) allows setting the length of the vector drawn from the bow of each
target. The Vector lengths are computed multiplying the target speed by this time value; therefore, the
length of the vector, represents the echo position according to the set minute’s value. The line of the
vector is dashed.
Figure 5.5 Vector Time
Placing the trackball cursor over the label, the help line will change to “Decrease”, “Enter Value” and
”Increase”; therefore, using the left and right SKs the operator will change the value of a unit for each
click. Pressing the centre key, the alpha numerical keyboard will be visualised to directly enter a new
value. The vectors could indicate the True or the Relative speed. The selection is performed by
means of the True / Relative Vector button, placed below the Vector Time label. The Vectors are not
visualized if the RADAR TARGET Symbols are Off.

TRUE / RELATIVE VECTOR
The True / Relative Vector button function (parag 3.2.6 and parag.3.2.5 ) is to toggle the visualization
of the vectors on the PPI between True and Relative speed. Toggling to True Vector is not possible in
case of Gyro or Speed Log failure. If the vectors are in True presentation mode and one of the
sensors (gyro or speed log) fails, the presentation is automatically switched to Relative.
