AOPA Expo 2008 gave the Aero-TV crew a chance to catch up with
the latest and greatest from Xerion Avionics. This time we got a
long look at the with the AuRACLE CRM 2120 twin-engine
monitoring system. The CRM 2120 is designed to be a total
replacement system for aged/old tech engine gauges with a single
integrated monitoring system that will make engine management
shores a far less tasking effort.
Xerion representatives state the AuRACLE shortens the scan
required by scattered and outdated steam gauges by providing a
localized and innovative display. The AuRACLE CRM 2120 displays
engine data on dual 5.0" sunlight-readable LCD displays (now
available in either vertical or horizontal formats), and offers
military-grade reliability.
Engine and fuel data from both engines appear on two five-inch,
sunlight-readable, LCD screens. Operation info such as MP, RPM and
fuel flows are displayed on the upper screen, along with critical
engine parameters, including CHT, EGT and TIT. The lower screen
displays fuel and oil status, percentage of horsepower, OAT and
more. The CRM 2120 is manufactured to military specifications with
a single, remote-engine interface penetrating the firewall in each
nacelle.
With all the emphasis being given on retrofitting and upgrading
attitude, navigation and communication displays, it's an honest
pleasure to see a solid effort to bring 21st Century technology to
engine data and management -- especially when it looks THIS
good.
The CRM 2120 is manufactured to military specifications with a
single remote engine interface penetrating the firewall in each
nacelle. Xerion tells ANN that the AuRACLE CRM2120 is a dual-box
networked system, where the system's EIU (Engine Interface Unit) is
mounted on the engine-side of the firewall and where ALL engine
sensors connect directly to the EIU, 'over there.'
Engine and fuel data from both engines appears on two 5-inch
sunlight readable LCD screens. Operation info such as MP, RPM and
fuel flows are displayed on the upper screen, along with critical
engine parameters, including CHT, EGT and TIT. The lower screen
displays fuel and oil status, percentage of horsepower, OAT and
more.
The engine data is transmitted via a networked CAN bus to the
Display Unit using a single bulkhead connector on each firewall.
From there, a second cable marries up with the DU. Xerion notes
that this networked system 'reduces wire runs, thereby
significantly reducing installation costs and is very advantageous
for pressurized aircraft.' The AuRACLE CRM2120 networked system
architecture also allows for future expansion to communicate with
other networked Xerion engine monitoring systems.
