Once flight has entered the OAC, CPDLC will be utilised (initially tactically) such that the pilot will be requested to send down the full loaded route in the FMC, which GAATS+ will conformance monitor from entry to exit. Once again only if non conformance would the controller be informed. Crew action is to respond by selecting the appropriate button that sends the FMS routing….not to freetext the whole route as has been seen during operational tests.

  • 54. FAQ’s FOR RLAT (Timeline) Airspace OTS Flight Planning Datalink Logon CPDLC ADS-C UM137 Oceanic Clearance Re- Clearance Enroute Phase Loss of Criteria NAT Contingency Procedures Datalink Handover How will the tracks be designed and indicated to operators ? The ANSP responsible for designing the tracks will identify the core tracks, (the tracks with the highest loading) from the Priority Route Message data, and subject to their location and other tactical considerations, will designate these tracks as the Rlat tracks. The Rlat tracks will be identified in Note 3 of the OTS Track Message. RLat will be at published OTS levels, but will only be between FL350- FL390, noting that levels can be left off the Rlat tracks in line with all other OTS tracks. 24.8.15 NATS PRIVATE
  • 55. FAQ’s FOR RLAT (Timeline) Airspace OTS Flight Planning Datalink Logon CPDLC ADS-C UM137 Oceanic Clearance Re- Clearance Enroute Phase Loss of Criteria NAT Contingency Procedures Datalink Handover What are the flight planning requirements associated with Rlat ? As detailed in AIC065/2015 operators wishing to fly on the Rlat tracks between FL350-390 are required to flight plan; Field 10a – Comms capability (J5–Inmarsat & J7–Irridium SATCOM) Field 10b – Surveillance capability (D1–ADS-C) Field 18 – RNP4 (inserting ‘PBN’ followed by ‘L1’) It is important that your Comms and Navigation status are correctly reflected in your submitted flight plan, otherwise you will likely receive a less optimal Oceanic Clearance. 24.8.15 NATS PRIVATE

FAQ’s FOR RLAT (Timeline) Airspace OTS Flight Planning Datalink Logon CPDLC ADS-C UM137 Oceanic Clearance Re- Clearance Enroute Phase Loss of Criteria NAT Contingency Procedures Datalink Handover What are the AFN_CON (logon) procedures approaching the NAT? As detailed in GOLD (Global Datalink Document) crews are required to perform manual logon approximately 20minutes from the NAT boundaries, unless they are already logged onto an adjacent centre, who will perform the datalink handover process which is a seamless process to the crew. 24.8.15 NATS PRIVATE
  • 57. FAQ’s FOR RLAT (Timeline) Airspace OTS Flight Planning Datalink Logon CPDLC ADS-C UM137 Oceanic Clearance Re- Clearance Enroute Phase Loss of Criteria NAT Contingency Procedures Datalink Handover What will happen if the logon is not performed or cannot be achieved? Should the crew fail to peform a logon in good time, the controller will be alerted to the fact that the aircraft no longer meets the criteria to be eligible to be cleared on the Rlat track, and subject to the traffic situation at that time, will be likely to receive a revised non Rlat clearance. If the logon fails during the handover process, the transferring agency will contact the flight and instruct the crew to perform a manual logon to avoid a re-clearance being issued. 24.8.15 NATS PRIVATE
  • 58. FAQ’s FOR RLAT (Timeline) Airspace OTS Flight Planning Datalink Logon CPDLC ADS-C UM137 Oceanic Clearance Re- Clearance Enroute Phase Loss of Criteria NAT Contingency Procedures Datalink Handover Why do you need connections in place prior to entering the NAT? ADS-C provides our procedural controllers with a regular update of where the flight is (14minute reports) as well as instant reports should the flight deviate from clearance. CPDLC provides a fast communication capability to the controller that assures a level of intervention capability. It is this Comms and Surveillance capability that permits reductions in standard separations in remote areas such as the North Atlantic. 24.8.15 NATS PRIVATE
  • 59. FAQ’s FOR RLAT (Timeline) Airspace OTS Flight Planning Datalink Logon CPDLC ADS-C UM137 Oceanic Clearance Re- Clearance Enroute Phase Loss of Criteria NAT Contingency Procedures Datalink Handover Why and when will be you be sending UM137 (Confirm Assigned Route)? In addition to utilising pre boundary ADS-C Demand reports, UM137 gives the controller assurance that the full oceanic route loaded into the active flight plan of the Flight Management System is in conformance. Shanwick will initially use UM137 tactically so as to monitor responses from crews, and to manage associated workload. When this assurance is gained, the adaptation will be set such that UM137 will be sent automatically 5 minutes after entry. Crews action is to send DM40 through enabled menu button. 24.8.15 NATS PRIVATE
  • 60. FAQ’s FOR RLAT (Timeline) Airspace OTS Flight Planning Datalink Logon CPDLC ADS-C UM137 Oceanic Clearance Re- Clearance Enroute Phase Loss of Criteria NAT Contingency Procedures Datalink Handover How is Shanwick issuing Rlat Oceanic Clearances when flight has not yet established datalink communications? Our system will initially use the Flight Plan information to base a clearance, as it does for MNPS and RVSM. At pre-determined times our system will then look for the associated logons and establishment of CPDLC connections and ADS-C contracts prior to entry. Should any of those not be established the flight will no longer meet the criteria, and will be subject to a re-clearance. 24.8.15 NATS PRIVATE
  • 61. FAQ’s FOR RLAT (Timeline) Airspace OTS Flight Planning Datalink Logon CPDLC ADS-C UM137 Oceanic Clearance Re- Clearance Enroute Phase Loss of Criteria NAT Contingency Procedures Datalink Handover What is likely to happen should a flight be subject to a re-clearance? Should a Shanwick planning controller be made aware that a flight no longer meets the criteria for the Rlat clearance, then subject to traffic and separations a new clearance outside the Rlat track area will be considered. ATC Procedures are being finalised such that the Oceanic controller will call domestic who will then liaise with the crew accordingly. 24.8.15 NATS PRIVATE
  • 62. FAQ’s FOR RLAT (Timeline) Airspace OTS Flight Planning Datalink Logon CPDLC ADS-C UM137 Oceanic Clearance Re- Clearance Enroute Phase Loss of Criteria NAT Contingency Procedures Datalink Handover What is likely to happen should a flight be subject to a re-clearance? It is important that a swift ATC decision is reached and implemented to avoid unnecessary workload, and therefore it is important for crews to respond quickly. Ensuring that the appropriate request for oceanic clearance in relation to the datalink capability is made, is important to avoid late changes to Oceanic Clearance, which will result in higher workload both to ATC and the crew. 24.8.15 NATS PRIVATE
  • 63. FAQ’s FOR RLAT (Timeline) Airspace OTS Flight Planning Datalink Logon CPDLC ADS-C UM137 Oceanic Clearance Re- Clearance Enroute Phase Loss of Criteria NAT Contingency Procedures Datalink Handover Is there any difference to operations when the flight has entered the NAT? Should a flight lose criteria (manually logs off by selecting ATC COMM OFF) then our system will output associated warnings. The oceanic controller will then attempt to have the connections re- established prior to initiating an enroute re-clearance. Shanwick will be utilising UM79 (re-route) clearance message as part of the system update, noting that crews will continue to be required to reconnect to flight plan should a reroute result in a discontinuity at the oceanic exit point. 24.8.15 NATS PRIVATE
  • 64. FAQ’s FOR RLAT (Timeline) Airspace OTS Flight Planning Datalink Logon CPDLC ADS-C UM137 Oceanic Clearance Re- Clearance Enroute Phase Loss of Criteria NAT Contingency Procedures Datalink Handover What is likely to happen should a flight be subject to a re-clearance? It is important that ADS-C provides the improved surveillance capability, and CPDLC provides swift communications. Therefore should either of these components be lost, then the controller is required to re-establish them or revert to standard separations by issuing re-clearances. Correct flight planning and use of datalink functionality will mitigate against re-clearances. 24.8.15 NATS PRIVATE

As part of the success criteria for Phase 1 of the trial, Shanwick will be monitoring datalink performance both in terms of system but also user actions, so that improvements can be put in place to mitigate poor performance. As part of that, operators will be contacted should investigations indicate incorrect flight planning or operation. 24.8.15 NATS PRIVATE

FAQ’s FOR RLAT (Timeline) Airspace OTS Flight Planning Datalink Logon CPDLC ADS-C UM137 Oceanic Clearance Re- Clearance Enroute Phase Loss of Criteria NAT Contingency Procedures Datalink Handover How does Rlat impact the NAT Contingency Procedures? As stated in the revised AIC for RLAT, and the Special Emphasis Items Ops Bulletin (003), there are no changes to the in flight contingency procedures weather deviation procedures as detailed in PANS ATM Doc444 Para15.2 & 15.2.3. Pilots must stringently follow all measures for avoiding conflict with other aircraft provided for in the PANS ATM Doc4444. 24.8.15 NATS PRIVATE

FAQ’s FOR RLAT (Timeline) Airspace OTS Flight Planning Datalink Logon CPDLC ADS-C UM137 Oceanic Clearance Re- Clearance Enroute Phase Loss of Criteria NAT Contingency Procedures Datalink Handover What should crew do if there is a datalink handover failure at the boundary? As stated in the GOLD (Global Datalink Document) the datalink handover process should be seamless to the crew. If the handover fails, then ATC will instruct the crew accordingly. Normal response is for crew to be instructed to select ATC Comm Off and logon to next agency. It is important that this is done, otherwise the receiving ANSP will not indicate the appropriate criteria and as stated before may consider a re-clearance. 24.8.15 NATS PRIVATE
