Usage Notes

  • The Message 26 TOI Message format provides for both a broadcast and addressed TOI message variation. Addressing, when required, shall be performed using the Destination Indicator and Destination ID fields inherent to the Message 26 structure.
  • The report is intended to be repeated every 15 seconds until cancelled locally. The PI shall not retransmit if an ACK is not received.
  • Cancelling a TOI locally stops transmission of TOI message repetitions.
  • Remote units receiving a TOI will apply Lost Target/Auto Drop processing rules to remove the TOI designation from a target.
  • Cancellation messages repeat four (4) times, 15 seconds apart. The PI shall not retransmit the cancellation message if an ACK is not received.
  • This message can be used to report either vessel or aircraft targets.
