UniLink UL-800/801 FANS SCN 30.X Operator’s Manual   23-20-06.02  1 December 2011   INTRODUCTION The  UniLink  Airborne  Datalink  Product  (hereafter  referred  to  as “UniLink”) is an air-to-ground digital data communication system that operates  with  Universal  Avionics  Systems  Corporation’s  (UASC’s) Fight Management Systems (FMSs). It is capable of using a variety of media  such  as  Satellite  Communications  (SatCom)  and  Very  High Frequency  (VHF)  communications  to  exchange  data  with  datalink service  providers  (DSPs).  When  communicating  over  the  Aircraft Communications  Addressing  and  Reporting  System  (ACARS) network,  UniLink  is  the  functional  equivalent  of  an  ARINC  758 Communications  Management  Unit  (CMU).  The  UL-801  contains  an imbedded  VHF  data  radio  (VDR)  whereas  the  UL-800  requires  an external VDR. The VDR provides ACARS and various other types of network communications capability for UniLink. The  UniLink  Future  Air  Navigation  System  (FANS)  1/A+ implementation  is  intended  to  improve  safety  of  flight,  enhance efficiency, and increase air traffic capacity. Air traffic capacity increase is  promoted  by  augmenting voice  transmissions  between  crews  and ATC with datalink messages during flight in oceanic and remote areas that  have  limited  or  no  radar  coverage.  The  FANS  1/A+ implementation  is  defined  in  RTCA/DO-258A  and  ARINC  622. Features  of  this  implementation  include  Air  Traffic  Services  (ATS), Facilities  Notification  (AFN),  Automatic  Dependent  Surveillance-Contract  (ADS-C) ,  and  Controller-Pilot  Datalink  Communications (CPDLC) text data transmissions.  The  FAA  has  approved  the  aircraft  datalink  system  to  the  criteria contained in AC  20-140A for FANS 1/A+ using VDL M2, VDL M0/A, and  SatCom  (IMMARSAT).  The  datalink  system  meets  the  aircraft-allocated  performance  requirements  of  RCP  240  and  type  180  (all sub-networks),  and  the  performance  requirements  for  continental applications (VDL M2 only). This design approval does not constitute operational authorization.  NOTE: The colors shown on the screens in this operator’s manual are based  on  an  FMS  with  SCN  1000.5/1100.5  installed  and configured for STANDARD-2 color pallet.
 UniLink UL-800/801 FANS SCN 30.X Operator’s Manual  2  23-20-06.02  December 2011 Components One UASC  FMS utilizing  SCN  1000.5/1100.5 or later  is required for UniLink FANS-1/A+ implementation. A complete system includes: •  UASC  FMS  (SCN  1000.5/1100.5  or  later)  with  a  Control Display  Unit  (CDU)  or  Multifunctional  Control  Display  Unit (MCDU) •  FANS Visual Annunciator(s) •  FANS Aural Alerting device •  Cockpit  Voice  Recorder  (CVR)  (to  record  CPDLC/FANS messages and events) •  Approved  SatCom  System  (to  support remote oceanic FANS CPDLC communications) •  UniLink Airborne Datalink (SCN 30.X or later) - FANS Enabled will display the following MAIN MENU:
UniLink UL-800/801 FANS SCN 30.X Operator’s Manual   23-20-06.02  3 December 2011   MCDU Use of a UASC MCDU with the UniLink UL-80X involves the following configuration/operation performance considerations: •  When configured for a 429  interface,  LSKs [L6]  and [R6]  will not be functional •  When configured for a 702  interface,  LSKs [L5]  and [R5]  will not be functional (LSKs [L6] and [R6] will be used instead).  •  The plus/minus ( + ) key will not operate as a space key. The MCDU [SP] key is used for the space function.  UNILINK MENU on MCDU (429 Interface)
 UniLink UL-800/801 FANS SCN 30.X Operator’s Manual  4  23-20-06.02  December 2011 Applications FANS 1/A + is principally composed of three applications: • Controller-Pilot  Datalink  Communications  (CPDLC)  – CPDLC  allows  datalink  messages  to  substitute  for  traditional voice  communications  for  routine  communications  between  a crew  and  an  air  traffic  controller.  CPDLC  messages  can  be used to request and grant clearances, to inform the ground of the aircraft’s position and situation, and to provide instructions to the crew. • Air  Traffic  Services  Facilities  Notification  (AFN)  –  This application  requires  no  crew  action.  AFN  allows  the  aircraft and  an  Air  Traffic  Services  (ATS)  provider  on  the  ground  to exchange  addresses,  as  well  as  information  about  which FANS applications they support. •   • Automatic  Dependent  Surveillance-Contract  (ADS-C)  – This  application  requires  no  crew  action.  ADS-C  allows  ATS providers to query the aircraft to provide position reports and other  situational  data  at  regular  intervals  or  in  response  to events  specified  by  the  ATS  provider,  such  as  a  change  in altitude or lateral deviation.
UniLink UL-800/801 FANS SCN 30.X Operator’s Manual   23-20-06.02  5 December 2011    Operations NOTE:  This Operator’s Manual includes procedures and functions used in a FANS-Enabled UniLink System. Crews that operate this system must be trained and obtain operational approval from the state of registry.  Crew interface is accomplished through the FMS CDU and/or MCDU, utilizing a UASC FMS with SCN 1000.5/1100.5 or later. Data may be entered at any field highlighted by a cursor. The cursor is displayed in the first empty data field. Fields with plus signs (+) indicate information is required. Fields exhibiting minus signs (-) indicate input is optional.  If there is no cursor displayed in a data field, selecting the ENTER key will place the cursor over the first enterable field on the page. Data is then entered into the field using the CDU/MCDU alphanumeric keys. In some situations, flight progress and related data from the FMS will be prefilled. Subsequent presses of the [ENTER] key will move the cursor to the next enterable field. Pressing a line select key (LSK) highlights the corresponding data entry field. Selecting [ENTER] when the cursor is in the last data field on the page results in the cursor parking off of the page. Pressing [ENTER] again positions the cursor on the initial enterable field on the page.  FMS Input The FMS continuously provides current data to UniLink. Many messages and requests have fields that prefill with FMS flight progress data and computed information. In most cases the user accepts the data for inclusion into the message. It is possible however to change a value by overriding that value with a manual data entry. Manual entries are generally retained until power shutdown, although data that would normally change as a flight progresses will be cleared once the page has been exited (is no longer displayed).  Source FMS The  crew  must  ensure  that  the  FMS  that  is  navigating  the  aircraft (Source  FMS)  is  the  same  FMS  that  supplies  data  to  UniLink.  The Source  FMS  is  shown  on  the  SOURCE  FMS  page,  accessed  via MAINTENANCE > SENSOR STATUS > SOURCE FMS.
 UniLink UL-800/801 FANS SCN 30.X Operator’s Manual  6  23-20-06.02  December 2011   The Source FMS is indicated by an asterisk next to it. Any available FMS  can  be  manually  selected  by  pressing  the  adjacent  LSK.  If automatic  (AUTO)  selection  is  desired,  the  SELECTION  METHOD LSK will toggle between MANUAL and AUTO.  NOTE:  It is important for the crew to ensure that the Source FMS is not  changed  prior  to  an  expected  flight  plan  modification uplink. If the Source FMS is changed prior to the uplink, the flight plan  information will  need  to be transferred  to  the  new Source FMS from the previously designated FMS.  Communications Prior to entering Oceanic Airspace (and loss of VHF communications) the crew should suspend VHF and transition to satellite communication (See STATE under VHF DATA in the COMM CONTROL section).  Current Time On every UniLink screen above the RETURN option at LSK [5R], the current UTC time is displayed. SEND  When the SEND LSK is pressed, the request is placed into queue for transmission. The delivery status of the message appears above the SEND option. If data required for the message has not been entered completely, the SEND option will display as inactive and if selected, a pop-up  window DATA REQUIRED  will display (indicating the data is insufficient).The  SEND  prompt  will  not  display  an  arrow  (indicating active) until all required data is entered. Clear the pop-up window by pressing any active LSK.
UniLink UL-800/801 FANS SCN 30.X Operator’s Manual   23-20-06.02  7 December 2011      SEND  status  displays  the  current  status  of  the  message. When  the SEND LSK is pressed, the status will briefly change to QUEUED, then SENDING. The selected media for transmission (VHF, SAT, or TEL) is indicated after SENDING. When acknowledgement is received from the DSP, SENT status will display.

UniLink UL-800/801 FANS SCN 30.X Operator’s Manual   23-20-06.02  15 December 2011   Alerting Message Alerting Message alerting functions include visual and aural alerts, and digital outputs  to  various  Line-Replaceable  Units  (LRU).  The  outputs  are intended to drive visual or aural alerting when a new uplink message is received. The digital outputs provide messaging alerts that may be used  by  other  devices  for  additional  alerting  functions,  such  as  the FMS MSG annunciator.  Alert Inhibiting UniLink  Alert  Inhibiting  operates  in  order  to  suspend  the  output  of message  alerting  during  critical  phases  of  flight  (i.e.,  takeoff  and landing).  Displayed  UniLink  advisories  are  not  suppressed  during critical flight phases.  NOTE:  If UniLink transitions out of the takeoff phase due to transitioning directly into the landing phase, UniLink will continuously inhibit alert outputs. This ensures there are no aural alerts that could potentially distract the crew.

UniLink UL-800/801 FANS SCN 30.X Operator’s Manual   23-20-06.02  41 December 2011    LOG ON Menu Navigation: UNILINK MENU > ATC > LOG ON The ATC LOG ON page is used to log on to an ATC facility via the ATS Facilities Notification (AFN) application. This log-on functions as a datalink equivalent to voice initial contact.   Prior to initiating an ATC Log On, the following should be verified: •  The aircraft identification matches the identification in the filed flight plan •  The  flight  plan  contains  the  correct  aircraft  registration  and address •  (If planning to use ADS-C services), ADS-C is ENABLED  •  Prior to  ATC LOG ON, and throughout FANS operations, the crew  should  ensure  the  flight  path  intent  data  (waypoint Lat/Long, altitude, and offsets) of the Universal Avionics FMS providing  data  to  the  UL-80X  remains  synchronized  to  the navigating FMS by automatic or manual means for at least the next two waypoints. Appropriate  times  and  conditions  for  performing  an  ATC  log  on include: Time/Condition  ATSU/ATC Prior to takeoff (where permitted or required), but no earlier than 45 minutes prior to ETD Current ATSU for the FIR that the departure airport is located within. 15 minutes or more prior to FIR boundary estimate, above 10,000 feet Current ATSU for the FIR in which the aircraft is operating Less than 15 minutes prior to FIR boundary estimate, above 10,000 feet Next ATSU that provides CPDLC and/or ADS-C services for the FIR on that flight
 UniLink UL-800/801 FANS SCN 30.X Operator’s Manual  42  23-20-06.02  December 2011 Following an unsuccessful data link transfer to another ATSU or when instructed by ATC As instructed per above  LOG ON To perform an AFN log on: 1.  Verify  the  aircraft  identification.  Or  press  CALLSIGN,  LSK  [1L], enter an aircraft call sign, and press [ENTER].  2.  Press ATC, LSK [2L] to select an ATC facility. The ATC LOG ON TO  page  will  open for  selection  of  a  region.  A  region  selection opens listings of specific ATC facility identifiers. A facility ID may also be  manually entered.  Selecting  an  ATC facility returns  the display to ATC LOG ON 1/2.  3.  Once an ATC facility is selected, the LOG ON  option becomes active  (arrow  displays).  Press  LOG  ON,  LSK  [3L]  to  initiate  an AFN log on downlink message.  NOTE:  A successful AFN log on is indicated by SUCCESS displaying above the LOG ON option. The ATC facility may in turn initiate ADS-C and/or CPDLC connections with UniLink. AFN  log  on  failure  is  indicated  by  an  ATC  LOGON  FAIL advisory alert and a status of either TIMEOUT (no response to the  AFN  log  on  downlink  within  10  minutes)  or  ERROR  (if UniLink  received  an  error  response  to  the  log  on  downlink). The user may attempt another AFN log on or revert to voice communications. Automatic Dependent Surveillance-Contract (ADS-C) ADS-C  surveillance  is  dependent  on  automatic  downlink  information from onboard avionics triggered by specified events or time intervals. The  ADS-C  interface  (provided  by  the  ATC  database)  provides  the following functions: ADS-C  Disable/Enable  –  Pressing  LSK  [1R]  toggles  ENABLED  and DISABLED: •  ENABLED  allows  the  ADS-C  contract  with  ATC  to  be established •  DISABLED  suspends  ADS-C  communication  and  terminates all existing contracts.
UniLink UL-800/801 FANS SCN 30.X Operator’s Manual   23-20-06.02  43 December 2011   ADS-C  NORM/EMRG  –  Pressing  LSK  [2R]  toggles  the  ADS-C application  mode  between  Normal  and  Emergency.  This  will  also change the ADS-C mode on the ATC EMERGENCY page (and vice versa).  The ATC LOG ON page 2/2 (ADS-C STATUS) – Pressing the [NEXT] key displays the Status of each ADS-C connection (including ACARS address,  periodic  contracts,  event  contracts,  and  emergency/normal mode).  Controller-Pilot Datalink Communications (CPDLC) CPDLC is a two-way datalink system allowing controllers at a CDA to communicate text messages to the crew instead of using traditional voice communications.  When a successful AFN log on is established, a CPDLC connection can be made by the CDA. When the CDA establishes a CPDLC connection, the CPDLC status displayed at LSK [3R] changes from INACTIVE to ACTIVE. Selecting TERMINATE at LSK [3R] breaks all exiting CPDLC connections, returning the CPDLC status to INACTIVE. An ATC facility cannot establish another CPDLC connection with UniLink until the user performs another successful AFN log on.  NOTE:  The crew should exercise prompt response/closure following receipt of a CPDLC uplink. Open CPDLC uplinks should not be deleted.   CURR (Current) ATC and NEXT ATC These  fields  display  the  identifiers  for  the  CDA  and  Next  Data Authority (NDA).  Exiting a FANS Service Area: Approximately  15  minutes  after  exiting  CPDLC  or  ADS-C  service areas, the following should display: ATC LOG ON 1/2: •  The CURR  ATC and NEXT ATC fields on ATC LOG ON  1/2 display dashes •  The CPDLC field, LSK [3R] displays INACTIVE •  The  ADS-C  field,  LSK  [1R]  displays  either  ENABLED  or DISABLED (but not ACTIVE)
 UniLink UL-800/801 FANS SCN 30.X Operator’s Manual  44  23-20-06.02  December 2011 ATC LOG ON 2/2: •  All five ADS-C connection fields display dashes NOTE:  If  a  CPDLC  or  ADS-C  connection  remains  active,  the  crew should take action to ensure the connections are terminated.
UniLink UL-800/801 FANS SCN 30.X Operator’s Manual   23-20-06.02  45 December 2011    LATENCY Upon  CPDLC  connection,  the  CDA  (ATC)  may  send  a  FREE-TEXT uplink with the desired message latency value. Latency may be reset by the crew to the ATC-specified value. Upon hand-off to a different ATC, a new value request may be received. The request will be in the form of SET MAX UPLINK DELAY VALUE TO [value] SECONDS or CONFIRM MESSAGE LATENCY TIMER OFF. To change the LATENCY value: 1.  Press LATENCY, LSK [4R].  2.  Using the numeric keys, type in the desired value (can be set to a non-zero value between 1 and 999). 3.  Press [ENTER]. To turn off the LATENCY function: 1.  Press LATENCY, LSK [4R]. 2.  Press the [BACK] key. 3.  Press  the  [ENTER]  key.  The  field  will  show  –SEC  to  indicate LATENCY is turned off.  Received  CPDLC  uplinks  can  have  an  optional  SENT  timestamp appended to the message (at ATC’s discretion). The message latency value is used by UniLink to determine if a received uplink is delayed by comparing the sent time to the system time at which the uplink was received.  The  delayed  status  of  a  given  message  is  displayed following the message text (example): 2211Z KZAK¨ NEW PROCEED DIRECT TO NUCAR (SENT 2205Z – DELAYED) The time stamp that follows the uplink ATC message will include the word DELAYED (“SENT 1234Z--DELAYED”). The crew may decide to respond  to  the  uplink  normally  or  to  contact  ATC  for  clarification. UniLink resets the message latency value to the default value stored in the configuration module whenever the aircraft is without a CPDLC connection  such  as  end  of  flight,  commanded  termination,  etc.  The latency value is not automatically reset during a CPDLC handoff.

UniLink UL-800/801 FANS SCN 30.X Operator’s Manual   23-20-06.02  83 December 2011    UL-800 with External VDR The  VHF  VOICE  page  is  used  to  enable/disable  VHF  voice  mode. LSKs [1R] and [2R] allow selection of the MODE as  either DATA or VOICE respectively (an asterisk <*> indicates the selected mode).  DATA Mode - UniLink data communication; no voice communications. UniLink will tune to the appropriate datalink frequencies only.  VOICE Mode - UniLink no longer communicates  via  VHF to  support datalink  communications.  The  external  VDR  is  used  for  voice  and voice frequencies are tuned via VOICE FREQ, LSK [3L]. VHF voice frequency can be tuned from this page if Voice Frequency Control enabled in configuration. Valid frequency range is: •  If  configured  for  frequency  spacing  of  25KHz  -  118.000  to 136.950 •  If  configured  for  frequency  spacing  of  25KHz/8.33KHz  - 118.000 to 136.965 and 136.980 to 136.990 NOTE:  The frequency 136.975 is a reserved frequency.
