Cockpit Voice Recorder
The world’s smallest, lightest, and lowest power cockpit voice recorder designed for ED-112A compliance.
FAA TSO APPROVED – SENTRY™ CVR
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.
