Retrofittable 21st Century Engine Management -- For Twins!
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Xerion representatives state the AuRACLE shortens the scan required by scattered and outdated steam gauges by providing a localized and innovative display.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.
