The most distinguishing feature of the Cockpit
Voice/Flight Data Recorder (CVFDR) is its internal Recorder Independent
Power Supply (RIPS) option, which provides a backup power source in the
event of a main power failure without the headache of maintaining
batteries. Backup power allows the CVFDR to record data for 10 minutes
after a power failure and meets emerging requirements for cockpit voice
and digital flight data recording presented by the National
Transportation Safety Board (NTSB) and the latest FAA TSOs.
