EFDMU - Flexible ARINC-600 Data Management Solutions

The Enhanced Flight Data Management Unit (EFDMU) is a highly configurable avionics unit developed to host FDAU, DMU, QAR and FOQA/ FDM functions in an ARINC 600 form factor. Input interface options include all major avionics bus families and all major analog sensor/transducer types. Acquired data can then be transmitted to ED-112 compliant FDR systems, recorded to removable quick-access CompactFlash memory cards or transmitted via network devices (e.g. a wireless quick access transceiver).

All acquisition functions are designed using high reliability FPGA based logic in accordance with DO-254 processes. End-users also have the option of hosting program specific DO-178 applications within their systems, such as an Aircraft Conditioning Monitoring System (ACMS), an Operational Loads Monitoring (OLM) system or an iVHM (integrated Vehicle Health Management) system.

Internally the EFDMU is built using Curtiss-Wright’s “AviBlocks” (modular avionics building blocks) technology. AviBlocks derive from the Acra KAM-500 family which encompasses 100+ interface module types, and is used on 200+ platforms by 300+ users. This unique architecture allows avionics integrators to rapidly prototype solutions, and easily accommodate evolving requirements. The ARINC 600 EFDMU platform is uniquely suited to low-volume obsolescence replacements where high-cost developments are not possible.
