That's right! ACARS has some very interesting information in it. Just a few things of notable interest: - realtime routing plans/changes - OOOI (out/off/on/in) revealing when an airframe takes off or lands - departure, destination airports and gates - weather and other flight bag data - airline / flight crew communication - flight crew / airport communication - positional data (which can be useful to augment or verify when ADS-B data is not available) It has been a time consuming process to do research on some of the extended text (see: https://github.com/airframesio/acars-message-documentation https://github.com/airframesio/acars-message-documentation), but we hope to keep at it.
