Due to the fact that the bearing scale relates to the position of the CCRP in the PPI, the division of the
bearing scale is altered in a way that the scale still fits to the de-centered position of the CCRP.
In the case that a very large ship uses a very
small scale for the display (e.g. 250m) it might
happen that parts of the ship´s outline are situ-
ated outside of the PPI. But neither the CCRP
nor the indication of the position of the selected
radar antenna itself can ever leave the PPI,
regardless of the settings for CCRP.
Before either the CCRP or the indication of the
position of the selected radar antenna will leave
the PPI, they will be shifted back to the oppo-
site point where they are supposed to leave
according to the ship´s movement at the time
when the CCRP/the antenna indication have
reached 70% of the radius of the PPI, meas-
ured from the centre.
