Acarsdeco2 Windows | Download

Verdict: For pure ACARS decoding in Windows, Acarsdeco2 is unbeatable for speed and automation.

One of the most rewarding aspects of ACARS decoding is sharing data with the global community. Acarsdeco2 can output JSON or raw text over UDP to aggregators.

To feed to ACARS Hub: Run Acarsdeco2 with the --http or --udp options (check your version’s help via acarsdeco2.exe -h). Then configure the aggregator software to listen on localhost port 31001.

Some platforms that accept ACARS feeds:
