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.
