INTRODUCTION
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 UL-80X database-driven user interface and message set
is easily customized to match airline operational requirements
uploaded into the UL-80X without affecting product software or
certification status.
NOTE: The current UniLink 80X uses Software Control Number (SCN)
30.X. It is important to ensure that operating documentation
reflects the SCN being used.
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.
Components
A VHF receiver transmitter or ARINC 741 SatCom is required for full
ACARS communications. An airborne telephone system is required to
obtain weather graphics and is capable of providing limited ACARS
communication with some service providers.
Capabilities
The two-way data link allows the crew to request and receive
clearances, weather reports, and messages. Weather graphics are
available on UASC’s FMS using flat panel displays and air phone
equipment. UniLink advisories alert the crew to newly received
messages.

Operations
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 (1/3) > SENSOR STATUS > SOURCE FMS.

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). The crew must enable VHF communications
once again when reentering a VHF-available region.
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 key or LSK.

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 Advisories
The bottom left LSK on each UniLink page will display either the
UNILINK MENU prompt or UniLink advisories. UniLink advisories
notify the crew of UniLink activity that may require user action. Only
one advisory will display at a time in the order of priority. Pressing the
adjacent LSK allows viewing of the advisory message.
When no advisory is displayed, the advisory field is used to display the
UNILINK MENU prompt. Selecting this prompt displays the UNILINK
MENU.
When on an FMS page, UniLink advisories will be indicated by the
flashing MSG annunciator. Pressing the [MSG] key will allow viewing
of UniLink advisories and messages via the NEW MESSAGE Advisory
prompt (LSK [5L]). This will open the appropriate UniLink page.

INVALID SECONDS The entered seconds value within
a latitude or longitude field is
invalid.
INVALID MINUTES The entered minutes value within
a latitude or longitude field is

DATA REQUIRED An attempt has been made to
navigate to a new page or send a

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.
