Nov. 30, 2009 – The Federal Aviation Administration (FAA) issued a Supplemental Type Certificate (STC) for Universal Avionics' new Cockpit Voice Recorder (CVR). The STC was issued by the FAA Transport Airplane Directorate; Los Angeles Aircraft Certification Office for the CVR-120R on the Hawker Beechcraft King Air series aircraft.

Technical Standard Order (TSO) approvals applicable to the CVFDR product line were also granted, as listed below.

  • TSO-C123b, Cockpit Voice Recorder Equipment
  • TSO-C124b, Flight Data Recorder Systems
  • TSO-C155 , Recorder Independent Power Supply
  • TSO-C177, Data Link Recorder Systems

The CVFDR also meets the requirements of EUROCAE ED-112, Minimum Operational Performance Specification for Crash Protected Airborne Recorder Systems, and the environmental requirements of RTCA/DO-160F. Now available for order, the CVFDR is offered in five model options to meet a variety of business, transport and rotorcraft applications.

Feature options include a choice or combination of cockpit voice or flight data recording, with and without internal Recorder Independent Power Supply (RIPS). The CVFDR's internal RIPS option is unique in CV/FDR market. The RIPS function provides a backup power source in the event of a main power fail.


According to the Notice of Proposed Rule Making (NPRM) for Cockpit Voice Recorders (CVR) and Digital Flight Data Recorders (FDR) (FAA-2005-20245), all forward-fit CVR installations in aircraft with more than 10 seats must have RIPS capabilities by March 2010. The CVFDR's internal RIPS option allows aircraft operators to meet this RIPS requirement without the additional weight of an external RIPS unit.

The CVFDR records 120 minutes of cockpit audio, stores 120 minutes of data link messages, supports 25 hours of flight data recording, and interfaces with data downloader tools that allow quick download of data from virtually any aircraft between flights. Bolt-down mounting eliminates extra weight and cost of rack trays. Weighing less than 9 pounds, the CVFDR combo unit is considerably lighter than other units available in the market, which provides additional fuel-cost savings.
