CVR - Cockpit Voice Recorder (records audio only)
FDR - Flight Data Recorder (records Parameters such as pitch, roll, altitude etc)
Combi - records both
Another type is coming which will do all the above plus image recording.
Anyway...suffice to say an AW109 is not "required" to have a recorder fitted but Agusta did make the decision to fit recorders wherever possible as a matter of course. The 109 was one of the borderline cases.
