ACARS Project Progress
2019-04-14 The inevitable happened: some funny guy (statistically it must be a guy) has used the ACARS system to spread offensive stuff among unsuspecting pilots. As the system was not designed to weed out jokers with surgical precision and ban them for good from the planet (there was no Facebook or Twitter or Google with omnipotent identity cancelation powers 20 years ago), I am currently contemplating how to stop the comics. So please beware the jokers and give me some time to come up with a workable solution that fits in with our hobby. What do pilots do when there is a joker on the frequency? (hint)
2019-02-09 I added TLS (HTTPS) to the web server. However, many client software packages do not work yet with HTTPS, so you may try but the URL below is what is guaranteed to work.
2018-02-25 Nothing changed, except the hardware, operating system, database, programming language revision, country of the server location, IP address, and some other details of the system.
IMPORTANT: older (>10 years) ACARS client software still refers to a network connect URL with 'flightline' in the string. Please replace this by the correct URL:
2013-11-01 It is that time of the year again. ACARS and a lot of other systems are being set up to support WorldFlight 2013 as usual. Please take a moment to look into this major online event and fly along if you can!
2012-11-03 ACARS has been switched into Worldflight Mode. This means that some lists and most maps are now only showing aircraft known to participate in Worldflight 2012. If you participate and do not get listed, just mail me (address at the bottom of the page).
2012-11-01 Due to an unexpectedly loud default sound level, the ATC (CPDLC) application turned out to be rather jumpy. I added a volume control slider to the Setup dialog. Version 1.5.1, here.
2012-09-22 It is that time of the year again ... while the teams prepare for their epic journey around the globe, the ACARS system undergoes maintenance to make it ready for 24/7 support of the logistics.
2011-11-11 V1.9 of the aircraft client fixes up a few snags in the formatting of position report times and the inflight ETA. It also offers a convenient shortcut if you manually update the ETA and want to send the OOOI report ahead of automatic time.
2011-10-24 V1.8 of the aircraft client integrates VATSIM ATIS requests. This feature is still being fine-tuned at the server site, it will improve over the next days.
2011-05-07 V1.4.1 of the ATC client offers a poll interval setting in milliseconds.
2010-11-09 ACARS just reached the 400 active accounts mile stone. Thanks to this rather large user base for such a niche system, I am still committed to keep it running!
2010-11-07 ACARS has been switched back to normal operation after a brilliant World Flight 2010. Hope to see you all next year!
2010-10-31 Worldflight 2010 has been made active on ACARS. Some features, such as some maps, are dedicated to just Worldflight aircraft until Sunday November 7. If you want to join Worldflight, just send your aircraft callsign to email@example.com. More info at my Worldflight blog.
2010-10-23 In preparation for Worldflight 2010, I've added (guarded) Twitter bridging to certain ACARS message types linked to certain accounts (logon codes). To follow Worldflight, use for example http://twitter.com/Worldflight.
2010-09-11 A new documentation page was added to explain how to enable the ADS-C transmissions from an aircraft, so that it appears on the global aircraft position map.
2010-09-05 The ATC client has been updated with various usability features. The most noteworthy ones are: 1. transparent secondary windows, 2. options to make the secondary windows less intrusice, 3. Reply-via-CPDLC button in Telex (ACARS).
2010-08-28 I am busy adding interface sugar to the ATC program (the CPDLC client) to facilitate the integration with any radar scope out there. Controllers are invited to participate in the development by downloading the client and giving feedback on the VATSIM forums (Controller Talk, preferably).
2010-08-22 ACARS is getting more popular. After several years of putting myself in between the logon code requests and the ACARS system, I took the plunge to open up the self-service registration. Hopefully the trolls stay away.
2009-10-17 World Flight 2009 is coming up fast. As always, ACARS plays an important role in this event. Operationally it is used to coordinate many issues, and the maps it generates are very nice for event dissemination. There is more information online about how to use ACARS during WF2009.
2009-06-07 To facilitate nice maps for web sites of Virtual Airlines, I added a feature to the world map. You can now filter for all airplanes that share the prefix of a callsign, such as "BAW".
A research project at George Mason University (DC) required a shorter polling cycle than 60 seconds. The new
2009-02-15 One of the long-standing ToDo items was to enable the ATC position report. It is now an exact copy of the FANS-1 variant, which is shared between FMC PROG, FMC COMM, and ATC modes (and therefore cannot return to anything, just as in reality). V1.7.
2008-10-12 In preparation for World Flight, I added a VisualPS1 offset detector to the ACARS Airborne Client V1.6. This is only of use for people who use VisualPS1 with IPC 2.8, probably just two on the Earth. All the others may leave this selection in Setup undefined.
2008-09-13 ACARS Mini Server full "ping" implementation, which enables the ATC client to not time out planes that are quiet but remain online. Release 0.4.
The CPDLC system got a significant extension: ATC stations may now relay route files to planes via CPDLC. Of course not all sims know how to handle route files, but this is "not my problem" :-). Both a new ATC station and a new Airborne Station required.
2008-08-22 V0.3 of the ACARS mini server fixes an irritating bug that blocked all CPDLC message exchanges. A case of trying to be too clean in data sanitising...
Dispatch has a new release, with the option to change the sound file now in Setup, and also the option to change ACARS servers. Typically you want "localhost" if you run the mini ACARS server yourself.
2008-08-11 In preparation of the new ACARS mini server, the Airborne Station got the option to select a different ACARS server URL. Also added a switch to select pure UTC time on the clock, instead of listening to a connected simulator. The program is now called differently and installs in a different location, which will be my new installation pattern.
2007-10-28 New Dispatch Client, updated with recent developments around TOPCAT and such, sound, and now packaged with a Windows installer. Also new Airborne Client, with manually editable OOOI fields in case you don't have working data feed.
2007-10-26 Airborne 1.2 has integration with TOPCAT and also allows downloading FMC route files for other sims than PS1.
2007-10-21 Better internal structure leading to bugs fixed in the airborne client.
2007-10-20 Bugs fixed in the CPDLC client (ATC) that mixed up the effects when a CPDLC message came in with those for telex.
2007-10-12 Pre-Departure Clearance added, printing logic restored to a sane state, and a few minor cosmetical fixes. V1.0 with Windows installer. Armable reports still absent, which probably nobody will notice anyway.
2007-09-30 Emergencies and When-Can-We added, ATC keystroke logic improved (the MCDU cannot detect holding the ATC key down, but it can detect pushing it twice within two seconds -- this will get you to the Emergency page straight away). Many smaller things fixed up. It now gets somewhere. Major thing lacking: armable (automatically sent) reports. 0.7.5.
2007-09-29 Reports added and Verify totally rewritten in the airborne client 0.7.4.
2007-09-22 Small polishings and a Windows installer instead of a plain .zip file.
2007-09-21 Full addition of the telex capability so that controllers have both communication systems in one client program. Sound library still not configurable except by overwriting the meepmeep.wav file.
2007-09-19 Quick and dirty addition of a sound when a CPDLC message comes in. Will get configurable. Please report whether it works.
2007-09-18 Airborne client up to 0.7.2. Fixed a problem with complete ATC log printing (from the ATC Index Page) and added some white space at the bottom of each print, for typical flight deck printer form feed.
2007-09-15 Airborne client up to 0.7.1. Can now print and some leftover items from SB747 have now been removed.
2007-09-15 ATC client up to 0.7.1. Now has usability improvements for departure clearances and other long messages that repeat often, window management aimed at ATC scopes, and messages to planes not yet logged on.
2007-09-14 New releases 0.7 of airborne and ATC clients. Plane handover between centers included (look into the COMM message cluster) and lots of loose ends tied up.
2007-09-08 New release (0.6) of airborne and ATC clients. All required functionality is in there now, just a few bells and whistles missing.
2007-09-06 Busy redoing the ACARS web site. It was a mess, getting better now.
2007-08-19 The latest beta release of the airborne client gets closer to what it should eventually be. Serious usage of this is possible by now. The web site is getting better, slowly.
2007-07-04 As I slowly fix all open issues and add more and more pages to the airborne side of CPDLC, the thing becomes actually usable.
2007-06-20 CPDLC beta released, both ATC and aircraft side. Still needs work though.
2007-03-11 Start of ACARS revamp, including all web sites.
