Frequently Asked Questions


Why won’t my Cockpit Voice Recorder (CVR) download via Firefly when installed in the aircraft?

Per the requirements established in FAA TSO-C123b Minimum Operations Performance Standards (MOPS), the recorder must be removed from the aircraft for audio downloading. Non-audio downloading (UTC, rotor speed, data link, etc.) can be completed while the recorder is installed on the aircraft, provided the recorder is in the STOPPED state.  Consult the applicable Installation Manual found on UniNet for further information.
