FIG 4 − 5 − 3 NAS Stage A Controllers View Plan Display AIM 8/15/19  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.) 25 26 X X X X X XXXX # X X X AAL373 280C 191H-33 VIG123 310N 095 NWA258 170 143 AAL353 70 231 2734 R15909 170C 290 2103 N1467F 140 + 143 460 UAL33 100A 296 7700 EMRG 7600 RDOF 1200 1200 85 +++ + UAL712 310N 228CST 1 22 23 24 27 28 29 29 30 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 H H H H H H H H H H H H H RADAR SERVICES AND PROCEDURES 4 − 5 − 5 Surveillance Systems
