Integrated Flight Data Recorder System for ED-112A standard crash protection Requirement. Data audio and image or video in a single lightweight recorder.


The Sentinel ED-112 is Lightweight and compact full integrated flight Data Recorder and data acquisition unit (DAU), providing combination of cockpit voice (CVR), flight data recording (FDR), an airborne image recorder (AIR) and a data link recorder (DLR) in a fully integrated solution. This system is providing for military aviation and flight test installation (helicopters and fixed-wing aircrafts) who search a powerful system with a minimum cost, minimum weight and minimum size.

Today, the Sentinel unit, is the most advanced design for all type of data collection (Data,Audio,Image) with an increase recording capacity, and the smallest Flight data recorder, who cover Crash survival exigence of "ED-112 Standard" from EUROCAE.
