8/5/047110.65P CHG 1(3) D− Distance−based longitudinal.(4) W− Reduced Vertical Separation Minimum(RVSM).(c) Degraded RNP. Select when an aircrafthas notified ATC of a reduction in navigationcapability that affects the applicable separationminima.(d) Restrictions. Ensure restrictions accuratelyreflect the cleared profile.d. Queue Management.1. Manage all sector and coordination queues inaccordance with the appropriate message priority andthe controller’s priority of duties.2. In accordance with facility directives, ensurethat the messages directed to the error queue areprocessed in a timely manner.e. Window/List Management.1. Ensure that the situation display window titlebar is not obscured by other windows and/or lists.NOTE−The title bar changes color to denote when priorityinformation on the ASD is being obscured or is out of view.2. In accordance with facility directives, ensurethat designated windows and/or lists are displayed atall times.13−2−4. CONTROLLER PILOT DATA LINKCOMMUNICATIONS (CPDLC)a. Means of communication.1. When CPDLC is available and CPDLCconnected aircraft are operating outside of VHFcoverage, CPDLC shall be used as the primary meansof communication.2. Voice communications may be utilized forCPDLC aircraft when it will provide an operationaladvantage and/or when workload or equipmentcapabilities demand.3. When CPDLC is being utilized, a voicebackup shall exist (e.g., HF, SATCOM, Third party).4. When a pilot communicates via CPDLC, theresponse should be via CPDLC.5. To the extent possible, the CPDLC messageset should be used in lieu of free text messages.NOTE−The use of the CPDLC message set ensures the proper“closure” of CPDLC exchanges.b. Transfer of Communications to the NextFacility.1. When the receiving facility is capable ofCPDLC communications, the data link transfer isautomatic and is accomplished within facilityadapted parameters.2. When a receiving facility is not CPDLCcapable, the transfer of communications shall bemade in accordance with local directives and Lettersof Agreement (LOAs).c. Abnormal conditions.1. If any portion of the automated transfer fails,the controller should attempt to initiate the transfermanually. If unable to complete the data link transfer,the controller should advise the pilot to log on to thenext facility and send an End Service (EOS) message.2. If CPDLC fails, voice communications shallbe utilized until CPDLC connections can bereestablished.3. If the CPDLC connection is lost on a specificaircraft, the controller should send a connectionrequest message (CR1) or advise the pilot via backupcommunications to log on again.4. If CPDLC service is to be canceled, thecontroller shall advise the pilot as early as possible tofacilitate a smooth transition to voice communications.Workload permitting, the controller should alsoadvise the pilot of the reason for the termination ofdata link.5. Assume that all unanswered CPDLC messageshave not been delivered. On initial voicecontact with aircraft, preface the message with thefollowing:PHRASEOLOGY−(Call Sign) CPDLC Failure, (message).Ocean21 − Oceanic13−2−3
