Honeywell Receives TSO for Its Latest Retrofit-Capable Primus Epic

Honeywell received TSO (technical standard order) approval for its latest retrofit version of its Primus Epic control display system that will enable the viewing of electronic charts and weather information delivered via satellite.

The company says its new CDS/R (control display system/retrofit), known as "Phase IV," improves the interface functionality of current Epic MFD (multi-function display) and FMS (flight management system) by adding an advanced file graphics server LRU (line replaceable unit).

The new system, which will become available in this year's third quarter and will fit about a dozen aircraft platforms, includes features such as the ability to split the electronic chart windows and to independently control panning and zoom.  It also will have:

• Color 8X10 inch AMLCDs (active matrix liquid crystal displays).
• Scalable architecture to accommodate two, three, or four display configurations.
• The ability to grow with emerging CNS/ATM (communications, navigation, surveillance and air traffic management) operational and environmental requirements.

In addition, it will save weight, wire and power through system integration, and increase reliability by reducing the number of LRUs and increasing the use of LCD technology.

Because the CDS/R evolved from Honeywell's Primus 1000 and 2000, it uses the same IC-600 and new IC-615 IAC (integrated avionics computer) platform, to give it a high degree of system integration and functionality, Honeywell says, as well as the reliability of a mature system.  05-29-2007.
