Relative Display (R)
The relative speed of a target with respect of own
ship is displayed as a trail.
This is used to watch a target which is
approaching to own ship. The trail of fixed target
such as land, if own ship is moving, will be drawn.
In the illustration below, own ship is moving east
at a certain speed and other ship 1 is moving
east at the identical speed. And other ship 2 is
moving west at the identical speed. After a
certain period of time, the trails of three ships are
drawn.
The relative speed of a target with respect to own
ship is drawn as a trail. Since the ship 2 is
moving in the opposite direction at the identical
speed, the speed derived by adding the ship 2
speed and own ship speed is drawn as a trail.
The land is drawn as a trail of own ship speed as
the land moves at the own ship speed.
