Quick access recorder

A quick access recorder (QAR) is an airborne flight data recorder designed to provide quick and easy access to raw flight data,[1] through means such as USB[2] or cellular network[3] connections and/or the use of standard flash memory cards.[2] QARs are typically used by airlines to improve flight safety and operational efficiency, usually in the scope of their flight operational quality assurance plans.[4] Like the aircraft's flight data recorder (FDR), a QAR receives its inputs from the Flight Data Acquisition Unit (FDAU), recording over 2000 flight parameters.[1] The QAR is also able to sample data at much higher rates than the FDR and, in some cases, for longer periods of time. Unlike the FDR, the QAR usually is not required by a national Civil Aviation Authority on commercial flights and is not designed to survive an accident. Despite this, some QARs have survived accidents and provided valuable information beyond that was recorded by the FDR.[5]
