Many ACARS messages are transmitted often. The aircraft will only stop transmitting a message when a confirmation from the groundstation is received that the message is copied O.K.

This results in vast numbers of messages, up to 10.000 in 24 Hrs! Files may reach sizes of up to 4 MB and even more... (Here in Deventer I have an average filesize of 3 Mb/24 hr) Files this large are not easy to analyze. Most people monitoring ACARS are spotters. Spotters are most of the time only interested in registration marks and flightnumbers. To extract this information from a *.LOG file produced by Airmaster takes (much) time... Now it can be done automatically!

The current version of DACARS is 2.3(c). It comes with a large database with flightroutes, aircraft serial/type/owner, ICAO 4 letter identifiers and company information. It supports Lowe Airmaster 2.0, 3.0 and 2000, AEA Acars, Khalid Rafiq's KRACARS and WACARS. It keeps track of all registrations and all flights you heard. It can create dBASE and ASCII files, if you wish with aircraft types and flightroutes, you can view all unique messages from one flightnumber etc. In the registration database more then 10.000 aircraft can be found.
