  2. The flight identification to be used for the AFN logon shall be the same as that filed in the ATS flight plan.

  3. The AFN logon address for Daegu ACC is “RKDA”, and for Incheon ACC is “RKRR”.

  4. In case the aircraft enters CPDLC airspace from the airspace where the ATS Data link services are provided, follow air traffic controller’s instruction.

  5. In case the aircraft enters CPDLC airspace from the airspace where the ATS data link services are not provided, the AFN logon shall be conducted as follows.

    1. When entering from another FIR, it is recommended to logon 15 minutes prior to Incheon FIR boundary.

    2. When departing from airport within Incheon FIR, it is recommended to logon before takeoff or by the time to enter CPDLC enabled airspace after takeoff.

      When departing from airport within Incheon FIR, it is recommended to logon before takeoff or by the time.

    * In case of depart from airport within Incheon FIR and logon before takeoff, connection will be established with Deagu/Incheon ACC 3-5 minutes before enter CPDLC enabled Daegu·Incheon ACC airspace.

7.1.6 CPDLC specific procedure

  1. Communication between air traffic controller and pilot initiated via voice should be completed by voice.

  2. Communication between air traffic controller and pilot initiated via CPDLC should be completed by CPDLC.

  3. The downlink response “WILCO” indicates that the instruction is understood and will be complied by the pilot.

  4. Pilot readback for ATS clearance/instruction issued via CPDLC is not required.

  5. In case the pilot is unable to comply with an ATC instruction uplinked via CPDLC, the pilot shall close the message transaction by replying with "ROGER" or another appropriate downlink message, and request an alternative instruction via voice.

  6. Free text message(downlink) shall not be used.

7.1.7 Termination of Data Link Service

The termination of CPDLC connection shall be conducted by one of the methods as follows.

  1. When exiting Incheon FIR, “CONTACT [ATC facility] [frequency]” message is uplinked before crossing the boundary. The pilot should acknowledge to this message by sending "WILCO". After this communication is completed, an “END SERVICE” message will be uplinked to terminate the CPDLC connection.

  2. When a communication transfer instruction is given by voice, “END SERVICE” message will be uplinked to terminate the connection.

CPDLC specific procedure
7.1.8 Data Link failure

  1. When CPDLC connection cannot be established successfully, the pilot shall disconnect CPDLC and then initiate another AFN logon. If the pilot continuously fails to establish CPDLC connection, the pilot shall inform the controller.

  2. When the pilot recognizes a failure of CPDLC connection or abnormal operation, the pilot shall terminate CPDLC connection and inform the controller via VHF voice communication.

    Example)

    Pilot : CPDLC failure. Disconnect CPDLC. Continue on voice.

    Controller : Roger. Continue on voice.

  3. When the controller recognizes a failure of CPDLC connection or abnormal operation, the controller will instruct the pilot to terminate CPDLC connection.

    Example)

    Controller : CPDLC failure. Disconnect CPDLC. Continue on voice.

    Pilot : Roger. Continue on voice.

  4. When the controller wants CPDLC to be connected, the controller will instruct the pilot to initiate AFN logon via VHF voice communication.
