Lightweight and Compact Recorder

Universal Avionics’ “CVFDR” includes a line of Cockpit Voice (CVR) and Flight Data (FDR) recorders available in five model options, providing a customized recording solution for your aircraft. The CVFDR offers an independent as well as a combination or “combi” cockpit voice and flight data recording capability, each with an internal Recorder Independent Power Supply (RIPS) option. Weighing less than nine pounds, the lightweight and compact CVFDR is the most advanced and convenient recorder available today.

The CVFDR’s unique internal RIPS option provides a backup power source in the event of a main power failure and allows aircraft to meet the FAA’s latest RIPS requirement without the additional size, weight and complexity of an external RIPS unit. Universal’s proprietary technology provides these capabilities without the need to maintain internal batteries.

Universal’s CVFDR was developed in compliance with the newest, most rigorous testing and crash survivability standards stipulated by the U.S. Federal Aviation Administration (FAA) and other aviation authorities around the world. Operators can now meet all published and emerging regulations for cockpit voice, digital flight data and datalink recording with the convenience of a small, lightweight unit.
