distance of an object from own ship or (in
conjunction with the EBL) the distance
between two objects can be measured.

Toolset group, the VRM are superim-
posed in the PPI. VRM appear with the
same data as they have been displayed

at 50% of the displayed range.

Toolset group.
To switch off display of the VRM, clear the checkbox in the Toolset
group.

outside the visible range. Switch the VRM off and then on again, to return it to the visible range.
