This figure illustrates the controller’s radar scope (PVD) when operating in the full automation (RDP) mode, which is normally 20 hours per day. 

(When not in automation mode, the display is similar to the broadband mode shown in the ARTS III radar scope figure. Certain ARTCCs outside the contiguous U.S. also operate in “broadband” mode.)
