How It Works FANS 1/A Prior to first oceanic fir boundary, crew logs on once to establish flight plan and other necessary info (ADS-C) Ground-initiated contract(s) are established with the aircraft Contract specifies information and frequency of downlinks from aircraft 3 different types of contracts (CPDLC) Clearances/Requests may be sent and responded via FMS CDU Both standard messages sets and free text are available C&PS Flight Technical Services 22
ATS Facilities Notification Logon Review the following items in the ICAO flight plan to ensure proper filing: Item 10a - J in the Radio Communication and Navigation field to indicate data link capability, J1 = CPDLC ATN VDL Mode 2 J2 = CPDLC FANS 1/A HFDL J3 = CPDLC FANS 1/A VDL Mode A J4 = CPDLC FANS 1/A VDL Mode 2 J5 = CPDLC FANS 1/A SATCOM (INMARSAT) J6 = CPDLC FANS 1/A SATCOM (MTSAT) J7 = CPDLC FANS 1/A SATCOM (Iridium) Item 10b The D1 in the Surveillance field to indicate ADS-C capability; (FPLXGS/KZID700-N1234-IG -GLF4/M-SE2E3HJ5M1YBDFGIRWX/HD1 -KMWO2130 -N0480F350 DCT APE DCT MGW GIBBZ1 -KIAD0049 KHEF -PBN/A1B1C1D1L1O1S2 NAV/RNVD1E2A1 RNP4 DOF/130114 REG/N1234 EET/KZOB0019KZDC0031 SEL/HLCP PER/C ) C&PS Flight Technical Services 23
ATS Facilities Notification Logon The purpose of the AFN logon is to: Allows the aircraft to logon to ATC and transfer control Provide the ATSU with information such as the flight identification, registration and the aircraft address This information allows the ATSU to correlate the AFN logon information with its corresponding current flight plan C&PS Flight Technical Services 24
The Initial AFN Logon An initial AFN logon is needed when the aircraft does not already have an ADS-C or CPDLC connection, such as when: The aircraft is preparing to depart; or The aircraft will enter an area where data link services are available from an area where data link services are not available; or Instructed by ATC (e.g., following a failed data link transfer) C&PS Flight Technical Services 25
ATS Facilities Notification Logon When initiating the logon, the flight crew should verify the following: The aircraft identification provided when initiating the logon exactly matches the aircraft identification (Item 7) of the filed flight plan; The aircraft registration provided when initiating the logon exactly matches the aircraft placard, when the flight crew manually enters the aircraft registration The flight crew enters the four character ICAO identifier of the ATSU to which the AFN logon is to be sent DNLN READY DNLN C&PS Flight Technical Services 26
ATS Facilities Notification Logon ATSU Identifier C&PS Flight Technical Services 27 C&PS Flight Operations 27
ATS Facilities Notification Logon Following the AFN logon, the ATSU sends a system level message to the aircraft avionics. This message is known as the Connection Request message ATSU establishes themselves as the Controlling data authority (CDA) Flight crew will receive a message indicating communication is established C&PS Flight Technical Services 28
Successful AFN Logon A successful logon displayed by the FMS after the logon is accepted by ATC center C&PS Flight Technical Services 29
Data Link Connection Management When transferring CPDLC and ADS- C services between FIRs, the flight crew should not need to reinitiate a logon Under normal circumstances, the current and next ATSUs automatically transfer CPDLC and ADS-C services The transfer is seamless to the flight crew The flight crew should promptly respond to CPDLC uplinks to minimize the risk of an open CPDLC uplink message when transferring to the next ATSU C&PS Flight Technical Services 30

How It Works ADS-C Once log on is established, the ATSU establishes one or more contracts with the aircraft: Periodic contract Event contract Demand contract Each contract may contain various information regarding the aircraft position, route, meteorological conditions, etc. ADS REVIEW CONTRACT PERIODIC 576s MSG CONTENT: FLIGHT ID PRED ROUTE EARTH REF AIR REF METEOROLOG A/C INTENT ATC INDEX 1/2 ADDRESS DDLCAXA Although the setting of these contracts requires no crew action, they can be viewed by the crew on the FMS CDU C&PS Flight Technical Services 32
Periodic Contract A periodic contract allows an ATSU to specify: The interval at which the avionics sends an ADS-C report The optional ADS-C groups that are to be included in the periodic report The ground system may permit the controller to alter the periodic reporting interval to allow for situations where the controller desires a longer or shorter reporting interval An ATSU can establish only one periodic contract with an aircraft at any one time. Up to 4 ATSUs can each establish their own periodic contract and specify their own conditions for the report with the same aircraft at the same time C&PS Flight Technical Services 33
Event Contract An event contract allows an ATSU to request the avionics to transmit an ADS-C report whenever a specific event occurs. The event contract can contain multiple event types. These types of optional events include: Level/altitude range change event Lateral deviation event Vertical rate change event Waypoint change event An event contract remains in place until either the ATSU cancels it or all the specific events in it have been fulfilled C&PS Flight Technical Services 34
Demand Contract A demand contract is simply a request sent by the ATSU requesting position information from the aircraft The demand contract uses the existing periodic contract for reporting criteria by the aircraft C&PS Flight Technical Services 35
Contracts MCDU Commands The FMS provides the crew with information on the current requested ADS contracts. C&PS Flight Technical Services 36
Cancelling ADS Contracts The ATSU either automatically or manually cancels an ADS contract when it no longer needs ADS-C reports to avoid situations leading to congestion The ground system cancels ADS contracts when: The aircraft has crossed the FIR exit position and has passed beyond the normal back coordination parameter The ATSU has cancelled or finished the ATS flight plan for the aircraft The previous ATSU, the controlling authority or an adjacent ATSU needs no further surveillance or monitoring information for the flight C&PS Flight Technical Services 37
Cancelling ADS Contracts The flight crew can terminate contracts on the aircraft by disabling ADS from the ATC LOGON/STATUS page C&PS Flight Technical Services 38

CPDLC Connection Management The purpose of a CPDLC connection is to allow the exchange of CPDLC messages between an aircraft and an ATSU FANS-1/A aircraft can have two CPDLC connections established concurrently, each with a different ATSU Only one of these connections can be active at any given time C&PS Flight Technical Services 40
How It Works - CPDLC When a clearance uplink is received, the crew will have to respond with ACCEPT, REJECT, or STANDBY If the ACCEPT response is selected, a WILCO message is inserted that will be downlinked to the ATSU C&PS Flight Technical Services 41
How It Works - CPDLC The crew may send a request via the CDU for altitude, speed, offset and flight plan changes. C&PS Flight Technical Services 42
CPDLC Message Sets The CPDLC message set consists of a set of message elements most of which correspond to a radiotelephony phraseology CPDLC message elements are referred to either as: Uplinks (message elements that are sent to an aircraft), or Downlinks (message elements that are sent by the aircraft) Each message element has a number of attributes associated to it, including: A message number that uniquely identifies each type of message element. Uplink message elements are prefixed UM and downlink messages prefixed with DM A response attribute that defines whether or not a response is required for a message element, and if so, what type of response is required C&PS Flight Technical Services 43
Example Uplink Message Sets Vertical Clearances (41 messages) EXPECT [Altitude] EXPECT CLIMB AT [time] MAINTAIN [Altitude] CLIMB TO AND MAINTAIN [altitude] EXPEDITE CLIMB TO [ altitude] Crossing Restraints (21 messages) EXPECT TO CROSS [position] AT [altitude] CROSS [position] BETWEEN [altitude] AND [altitude] Lateral Offsets (9 messages) OFFSET [distance offset] [direction] OF ROUTE PROCEED BACK ON ROUTE REJOIN ROUTE BY [position] C&PS Flight Technical Services 44
Example Uplink Message Sets Route Modifications (28 messages) PROCEED DIRECT TO [position] EXPECT [route clearance] EXPECT FURTHER CLEARANCE AT [time] Speed Constraints (16 messages) AT [time] EXPECT [speed] MAINTAIN [speed] INCREAS SPEED TO [speed] Contact/Monitor/Surveillance Requests (11 messages) CONTACT [icaounitname][frequency] SQUAWK [beacon code] C&PS Flight Technical Services 45
Example Uplink Message Sets Report/Confirmation Requests (25 messages) REPORT LEVEL [altitude] CONFIRM POSITION Negotiation Requests (5 messages) WHEN CAN YOU ACCEPT [altitude] Air Traffic Advisories (6 messages) ALTIMETER [altimeter] RADAR SERVICE TERMINATED Additional Messages (5 messages) WHEN READY DUE TO TRAFFIC DISREGARD C&PS Flight Technical Services 46
Multi-Element CPDLC Messages A CPDLC message consists of either a single message element, or a combination of up to five message elements. A CPDLC message that consists of more than one message element is a multi-element message. However, only one response is required for a multi-element message C&PS Flight Technical Services 47
CPDLC ATC INDEX Menu The ATC INDEX pages gives access to ATC data link related pages that allow... Declaring and sending emergency information Requesting altitude/speed/offset requests Reviewing reports Providing position reports Negotiation requests to ATC Viewing and printing message logs Free text messages Requesting a route clearance Requesting voice contact C&PS Flight Technical Services 48
Message Log The FMS keeps a log of all messages for the flight The log indicates whether messages that still require action (OPEN) and those that do not (CLOSED) C&PS Flight Technical Services 49
Cancelling CPDLC Connections The flight crew can cancel CPDLC by logging off of the system C&PS Flight Technical Services 50
CPDLC Communications In addition to the benefits of the direct communications link, other advantages associated with CPDLC include: Allowing messages to be stored and reviewed as needed Reducing flight crew-input errors by allowing the loading of specific uplink messages into the FMS Reducing workload by supporting automatically transmitted reports when a specific event occurs, such as crossing a waypoint Automatic updating of the ATS flight plan when a specific downlink message is received (Aircraft Specific) C&PS Flight Technical Services 51
When to Use Voice & When to Use CPDLC When operating within airspace where CPDLC is available and local ATC procedures do not state otherwise, CPDLC should be the primary means of communication While CPDLC provides for ATC communications, voice may be a more appropriate means depending on the circumstances During an emergency, the flight crew would normally revert to voice communications However, the flight crew may use CPDLC for emergency communications if it is either more expedient or if they are unable to establish voice contact C&PS Flight Technical Services 52
Displays and Alerts ATC Comm Message Alerting (Gulfstream example) The crew is alerted to an incoming uplink message through a combination of CAS messages and unique aural tones Uplink Type Aural Alert CAS Message Standard Single Tone ATC MESSAGE (Flashes in cyan reverse video for 5 seconds, then remains steady Urgent Double Chime ATC MESSAGE (Flashes in amber reverse video until the master caution button is pressed, then remains steady) A new aural alert is generated each time a new uplink message is received CAS message is extinguished when the crew has viewed the MCDU message C&PS Flight Technical Services 53
