The Sentry Cockpit Voice & Flight Data Recorder (CVFDR) was designed by combining the standard features of existing CVFDRs with new approach to capturing and protecting flight data creating the foremost CVFDR of the future. Using a patent-pending innovative memory insulation technique Sentry offers small size, lower weight and less power consumption than traditional CVFDRs in a modular and flexible architecture.

Sentry meets or exceed all requirements of ED-112A as well as qualification to DO-160G and MIL-STDs-461, 810 and 704 environmental and power requirements. The rugged enclosure is ideal for airborne operational environments including commercial and military fixed-wing and rotary wing aircraft and can be mounted in any attitude.

The MAU (Modular Acquisition Unit or Modular Data Acquisition Unit) provides a custom solution to suit aircraft configurations with minimal engineering. The MAU is designed to fit general, business and military aircraft which require a standalone flight data acquisition system. The MAU’s robust machined aluminium enclosure, along with the MIL SPEC D38999 connectors, provides protection for most operational environments making it suitable for both fixed and rotary wing aircraft.

The MAU supports a wide range of signal input types including ARINC 717, ARINC 429, GPS signal, analog inputs such as synchro, pitot/statics & discretes. It provides a standard ARINC 717  and ARINC 429 output data stream which is compatible with ARINC 717 and ARINC 429 flight data recorders.

The RDC (Remote Data Concentrator) is a miniature line replaceable unit designed for data acquisition close to signal sources. The RDC can be used in conjunction with a Modular Acquisition Unit (MAU) or as a standalone device. The RDC configuration is flexible, such that it can be considered for any application that is able to interface with a high-speed ARINC 429 bus. 

The hermetically sealed compact design make the RDC the perfect data acquisition device for most locations on the aircraft.

Additional features included field loaded signal interface configurations. This allows a RDC to be reprogrammed to match specific signals at different locations on the aircraft.
