Cockpit Voice Recorder

The world’s smallest, lightest, and lowest power cockpit voice recorder designed for ED-112A compliance.


Cockpit Voice Recorder

The SENTRY Cockpit Voice Recorder (CVR) was designed by combining standard features of existing CVRs with a new approach. Using a patent-pending, innovative memory insulation technique, the SENTRY offers a small size, low weight, and less power consumption than traditional CVFDRs in a modular and flexible architecture. This “software free” recorder allows for aircraft specific configurations as well as the addition of creative and useful expansion capabilities.

SENTRY™ CVR Capabilities

Industry Leading SWaP

Advanced hardware design minimizes size, weight & power (SwaP). Weighs as little as 4.5 lb and requires only 4 Watts (nominal).

Multi-Interface Design

Supports Ethernet, ARINC 777 and ARINC-429 (auto detection), RS-422/485, Analog and discrete sensor inputs

TSO Certified & Environmentally Qualified

TSO and aircraft-specific configurations available. Qualified to DO-160G

Two Hours of High-Quality Voice & Messaging

Stores two hours of high-quality, 4-channel voice and datalink messaging

Reduce Costs with Modern Design & Architecture

The SENTRY’s FPGA architecture provides a unique software-free environment which reduces NRE costs during configuration.

Recorder Independent Power Supply (RIPS) Available

Integrated 10-minute Recorder Independent Power Supply (RIPS) available

Additional Information

Available in titanium, the SENTRY meets or exceeds all requirements of ED-112A and qualifies for DO-160G environmental and power requirements. The rugged enclosure is ideal for airborne operational environments including unmanned, commercial, military, fixed-wing, and rotary-wing aircraft.

SENTRY includes a range of aircraft interfaces including:

  • ARINC-717 and ARINC-429 (auto detection)
  • Ethernet
  • RS-422/485
  • Analog and discrete sensor inputs
  • Data Link recording
  • Four high or low-fidelity audio channels (configurable)
  • Rotor speed input


Expansion of SENTRY’s capabilities includes the acquisition functions designed for the FDS Modular Acquisition Unit (MAU). This capability converts the SENTRY into a Data Acquisition and Crash Recorder System, and more.
