Property Value

Remarks
This can be zero for DF18 (Extended Squitter from Non-Transponder devices) replies if the ControlField indicates that the message is coming from a non-transponder device that does not broadcast ICAO24 addresses in its AA field. It can also be zero for downlink formats that are either reserved for future use or for DF19 (military extended squitter) where the aircraft address field is not defined by the spec.
