Ar-Com: The ultimate Aircom and ground Communication server.

A revolutionary concept in aircom communications, Ar-Com is a fully open and customizable ACARS messaging system supporting downlink and uplink.

The message routing is fully configurable and extensible. Currently supported network links include SITA, the internet, databases and files. New gateways can be added at any time (SMS, …).

The message interpretation, message processing rules and message display rules are also fully configurable. The user or administrator decides how the information should be extracted and manipulated, and how it should be presented to the user.

In aviation, ACARS an acronym for Aircraft Communications Addressing and Reporting System is a digital datalink system for transmission of short messages between aircraft and ground stations via airband radio or satellite. The protocol was designed by ARINC and deployed in 1978, using the Telex format.

Shown below is an example of a connection to the SITA provider. Many other gateways can be attached to integrated into your Ar-Com system.

Ar-Com architecture

The Ar-Com server communicates with the Datalink server using a directory queue, one for incoming and one for outgoing messages. The downstream side is connected to the intranet or to the internet.

Air to ground, ground to air, ground to ground

Ar-Com provides ground-to-air, air-to-ground and ground-to-ground data communication from anywhere in the world! Using a web-browser, you can securely run an entire ACARS messaging system, using the intranet or worldwide secured internet tunnels. These messages may come and go through any gateway you want. With Ar-Com, messages can be automatically encrypted or checked for errors. Ar-Com is made to be run by air carriers of any capacity; even small carriers can benefit from the true power of Ar-Com, at an affordable price.


This is easily the most powerful feature of Ar-Com. Since it is impossible to foresee every conceivable messaging endpoint, we implemented a message routing facility which is capable of distributing messages trough e-mail, 3rd party message processors or databases. The routing editor integrated in ADM 2000 (Ar-Com's administration tool), is a full-featured VBScript editor which provides the user with ultimate freedom.

More than just a mailbox

In addition to the mailbox functionality, we provide a whole range of standard and optional tools for data processing, extraction and reporting.

  • file-extraction
  • crystal reports
  • engine trend monitoring
  • network monitoring
  • aircraft monitoring
  • alert reporter
  • security administration
  • auto-responders
  • quality assurance
  • re-processing
  • backup

Multi-user, multi-airline

The advanced Ar-Com security policy allows full tailoring of each user’s privileges in the application. In a multi-airline environment, Ar-Com can securely maintain a full separation of each airline’s data, but still use common infrastructure and gateway providers.

Message recognition and interpretation

  • Message recognition with priority rules.
  • Recognition and interpretation based on : relative or absolute character position, identifiers (sequences + position).
  • Interpretation supports repeating groups (character sequences).
  • Implementation of recognition and interpretation rules need no programming knowledge.
  • Visual control of message recognition and interpretation rules with life examples.
  • Assembly of multi-part messages.

Message transmission

  • Uplink messages can be formatted in structured templates.
  • Automatic CRC calculation (when needed)
  • Automatic message sequence generation
  • Transmissions with high,normal or low priority
  • Uplink message assurance with real-time tracking
  • Message transmissions with limited lifetime

Ar-Com FSD

Download more information on Ar-Com FSD.

Ar-Com FSD (Flight Situation Dashboard) is a part of our Ar-Com Suite and shows on a graphical map the planned route, with waypoints from the flightplan and the actual route and position of the aircraft. From the ACARS messages, planned and actual fuel, planned and actual flight level (in flight) is plotted on a graph. Some important airport information is also shown on the map, like METAR, short and long term weather forecast, temperature, NOTAM, AIRMET and SIGMET. Airlines can be fully aware of the potential weather impacts on their operation, including the ability to use the latest forecasts to evaluate expected en-route turbulence that may impact a flight as it progresses.

With FSD, flight operations can send uplink messages to the aircraft. Downlink messages are received and interpreted by the Ar-Com APS. In case of critical messages, the user gets an automatic alarm.
