SECTION III
MODEL 560 INSTRUMENTATION AND AVIONICS
The Primus 660 ColoRadar System is an X-band alphanumeric digital radar with display designed for
weather location and analysis and for ground mapping. The radar system can also be operated in
conjunction with Electronic Flight Instrument Systems (EFIS) and the Multifunction Display (MFD) to provide
radar video to the EFIS EHSI display and the MFD. The MFD display serves as the primary indicator for the
weather radar display, which is controlled by the WC-650 Remote Radar Controller. The system detects
storms along the flight path and gives the pilot a visual indication, in color, of storm intensity. Storm
intensity is displayed at five color video levels with black representing weak or no returns and green, yellow,
red and magenta showing progressively stronger returns. In ground mapping mode, video levels of
increasing reflectivity are displayed as black, cyan, yellow and magenta.
WARNING
THE SYSTEM PERFORMS ONLY THE FUNCTIONS OF WEATHER DETECTION
AND GROUND MAPPING. IT SHOULD NOT BE USED OR RELIED UPON FOR
PROXIMITY WARNING, ANTI-COLLISION OR TERRAIN AVOIDANCE.
The system consists of a receiver-transmitter antenna and an indicator with operating controls.
The remote radar controller (WC-660) is typically installed on the center instrument panel below the
copilot's RMU. A multifunction display controller (MC-800) is installed at the forward end of the pilot’s
pedestal. Some functions of the multifunction display interface with the radar; these are also discussed
under Electronic Flight Instrument System in this section.
