  • 5-2-26. ADS-B ALERTS

    1. Call Sign Mis-Match (CSMM). A CSMM alert will occur when the ADS-B broadcast call sign does not match the flight plan call sign.
      • PHRASEOLOGY
      • (Aircraft ID) YOUR ADS-B CALL SIGN DOES NOT MATCH YOUR FLIGHT PLAN CALL SIGN.
    2. Duplicate ICAO Address. If the broadcast ICAO address is shared with one or more flights in the same ADS-B Service Area (regardless of altitude), and radar reinforcement is not available, target resolution may be lost on one or both targets. Notify the OS/CIC of the aircraft call sign and location of aircraft.
      • NOTE
      • 1. If this occurs controllers should ensure targets remain radar reinforced or at least 6 NMs apart.
      • 2. Duplicate ICAO Address Alerts appear as “DA” and are associated with the Data Block (DB) on STARS and CARTS systems. Duplicate ICAO Address Alerts appear as “DUP” and are associated with the DB on MEARTS systems. Duplicate ICAO Address Alerts appear as “Duplicate 24-bit Address” on ERAM systems.
