PRIMUSr 660 Weather Radar

INTRODUCTION

R
The PRIMUS
digital radar that is designed for weather detection and ground
mapping.
The purpose of the system is to detect storms along the flight path and
give the pilot a visual color indication of rainfall intensity and turbulence
content. After proper evaluation, the pilot can chart a course to avoid
storm areas.
This appendix is an abbreviated operational description of the
R
PRIMUS 660 Weather Radar System. For complete operating
instructions, refer to Honeywell Pub. No. A28–1146–111.
THE SYSTEM PERFORMS ONLY THE FUNCTIONS OF WEATHER
DETECTION OR GROUND MAPPING. IT IS NOT INTENDED THAT
THIS SYSTEM EITHER BE USED OR RELIED UPON FOR
PROXIMITY WARNING OR ANTICOLLISION PROTECTION.

DESCRIPTION

The system consists of a receiver transmitter antenna (RTA) and a
single controller (dual controllers are optional). Radar information is
normally displayed on the MFD in the MAP mode.
In the weather detection mode, storm intensity levels are displayed in
four bright colors, contrasted against a deep black background. Areas
of very heavy rainfall are displayed in magenta, heavy rainfall in red,
less severe rainfall in yellow, moderate rainfall in green, and little or no
rainfall in black (background). Areas of detected turbulence are
displayed in soft white.
