UniLink UL-800/801
Operator’s Manual
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.

Operator’s Manual
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.

Operator’s Manual
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.

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.

OOOI
Menu Navigation: UNILINK MENU 1/2 > OOOI
OOOI pages record data about the current flight and flight history. The
OOOI option is available (if configured) at LSK [3L] on the UNILINK
MENU 1/2 page.
OOOI Operation
OOOI (Out, Off, On, In) reports allow a dispatch or schedule office to
track a flight as well as provide accurate flight times and block times.
Based on installation, UniLink may use inputs from one or more
doors, the parking brake, and weight-on-wheels (WOW) status input.
OOOI reports may also use digital inputs from devices such as the
FMS or configured Input/Output Processors (IOP).
UniLink monitors the state of each discrete and the WOW condition at
power-up, but does not issue any reports unless a change in state is
detected. The OUT requirement is met when all doors are closed and
then the parking brake is released. The ideal sequence is:
1) UniLink powered up with brake set and doors open
2) Doors closed
3) Brake released
4) OUT report generated
Once the OUT report has been generated, if the door happens to be
opened prior to takeoff, an OUT/RETURN IN report will be generated.
Once an OUT report is generated (and the door remains closed) a
change in the WOW status from on-ground to in-air will result in an
OFF report.
If UniLink is powered up or reset in flight, it will monitor the WOW
state, determine that the aircraft is airborne and ignore all changes in
status of doors and brakes. A change to the WOW status from in-air
to on-ground will result in the ON report.
For an IN report to be generated, UniLink must:
• detect an OUT transition
• detect an OFF transition
• detect an ON transition
30
23-20-06.01
December 2011
UniLink UL-800/801
Operator’s Manual
• and then detect that the door is opened
The IN time that is recorded for the IN event is the last time the brake
was set prior to the door opening, or the time that the door opens if
the brake was not set. The time for all other OOOI events is the time
that the UniLink detected the last state change required for the
transition to occur.
Ground Delay (Optional)
To determine OOOI status, navigate to the SENSORS 1/2 page.
A GROUND DELAY ADVISORY occurs when the configured time on
the Ground Delay Timer expires after doors closed /brakes released
(OUT event) but before Weight-Off-Wheels/Takeoff (OFF event).
The GROUND DELAY ADVISORY annunciation will display at LSK
[5L].
Pressing LSK [5L] will display the DELAY page. The crew can send a
ground delay report by following the procedure listed in the DELAY
