A flight data recording system (50) including a flight data recorder (FDR (12) with an integrated flight data acquisition unit (FDAU) (16). The FDR (12) has first and second interface ports for communicating with one or more external aircraft instrumentation subsystems. The system includes an digital communication bus (52) coupled to one of the interface ports and arranged to provide a communications pathway between the FDR (12) and the external aircraft instrumentation subsystems. A portable maintenance access terminal (70) is coupled to the system via a local area network bus (60).
