The Digital Data Set (DDS), AN\AYH-5(V) has been adopted as the US Navy standard Digital Data Set for the T-45A/C Goshawk Flight Trainer aircraft. The DDS consolidates the Airborne Video Cassette Recorder (AVCR), Mission Data Loader (MDL) AN/ASQ-215, and Airborne Data Recorder (ADR)/Signal Data Computer (SDC)/Advanced Signal Data computer into a single unit. The US Navy PMA-209 Terrain Awareness Warning System software is fully integraded in the DDS. The DDS also complies with MFOQA download requirements. It consists of three components, the Data Acquisition Unit (DAU), the cockpit-mounted intelligent Control Panel (CP) with ED-112 Certified Crash Survivable Memory Unit (CSMU), and a hand-carried non-volatile solid-state data storage device known as the Removable Memory Unit (RMU).
The DAU provides the core processing, I/O, and internal memory storage to support Video/Audio/Data recording, Mission Data Loading, Wireless, and Terrain Awareness and Warning System functionality.
The CP manages and controls the data exchange between the RMUs and other avionics subsystems via the aircraft’s Ethernet, RS422, and MIL-STD-1553 multiplex databus. The RMU serves as the transportable storage medium for both pre- and post-mission information exchange between ground station computers and the airborne system.
