RA800 Digital CCS Systems
The RA800 CCS is designed to meet present and
foreseeable requirements for all aircraft types. The RA800 provides
centralised audio control, interfacing to other aircraft systems,
and sophisticated intercom networks for the flight crew. It is
built on a foundation of intelligent modules, which enables systems
to be configured for the particular requirements of the aircraft
platform.
The core of the RA800 CCS is the
Communication Audio Management Unit (CAMU). All audio routing is
contained within the CAMU: this increases immunity to EMI by
considerably reducing the volume and complexity of aircraft
cabling. Other advantages include ease of installation,
weight saving and improved reliability gained through significant
cable reduction.
The crew interface to the system is
via Audio Control Panels (ACPs) for the control functions.
Connections from the ACPs to the CAMU are via digital links. For
RA800 equipment, the connection between the ACP and the CAMU is an
ARINC 429 bus.
RA800 is microprocessor controlled
with centralised CCS with embedded VWS. Where an
aircraft is required to undertake a variety of roles, the RA800
system can readily be software reconfigured on board.
The system interfaces to navigation,
radio and warning equipment either directly or by means of
the aircraft avionics bus (MIL-STD-1553). Sophisticated BIT is
carried out within all units that make up the RA800 CCS system.
This data is collated and can be sent to the aircraft maintenance
system. Voice and/or Tone warnings are produced either from an
embedded module within the RA800 CAMU or from a stand alone
unit.
