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.
