The first applications of digital recorders were in
avionics systems, where analog and tape based systems are gradually
being replaced by digital, solid-state recorders, which can monitor,
record and retrieve information in-flight as well as for post mission
debriefings.
These recorders, connected to a standard 1553 data-bus, monitor all
aircraft electronics systems, and the condition of critical mechanical
systems on board, utilizing the Health & Usage Management System
(HUMS). Multi-channel systems store all video feeds, including Helmet
Mounted Displays (HMD), Head-Up Display (HUD), multifunction displays,
and images received from the targeting pod or EO guided weapons. All
of this data is stored on removable memory modules, which interface
directly with the ground debriefing system. This allows flight records
to be instantly used for mission debriefing and post mission analysis.
With their large capacities and available processing power, these
systems are transformed into networked memory banks to provide all
networked systems with common access to virtually unlimited memory
capacity.
Among the solid-state avionics recorders available on the market are
TEAC's MDR-87 and MDR-80, Smith Aerospace's Digital Video Information
System (DVIS) and Airborne Video Solid-State Recorder (AVSR), RADA
Electronics Systems NCDR, and Elbit System's DVR.
