// All known DF's 16 or greater are long. All known DF's 15 or less are short. // There are lots of unused codes in both category, so we can assume ICAO will stick to // these rules, meaning that the most significant bit of the DF indicates the length. // ...
Single bit errors correction using the 24 bit CRC. Ability to decode DF11, DF17 messages. Ability to decode DF formats like DF0, DF4, DF5, DF16, DF20 and DF21 where the checksum is xored with the ICAO address by brute forcing the checksum field using recently seen ICAO addresses. ...
VDL2 message addressing is based on ICAO 24-bit hex codes (same as ADS-B). dumpvdl2 may use your basestation.sqb database to enrich logged messages with aircraft data (registration number, operator, type, etc). If you want this feature, install SQLite3 library: sudo apt install libsqlit...

However, for full awareness about an aircraft's capabilities, version information has to be taken into account. It is encoded in the operational status message which is sent around every five seconds. Thus, decoding ADS-B has to be done in a stateful manner. Libadsb includes a stateful ...
