The following paragraphs describe typical weather radar display
formats for the PRIMUS

650 Weather Radar System, as shown in
Figure 4--40. The PRIMUS

is similar. The PRIMUS
R
870 also has ground clutter reduction (GCR),
turbulence (TURB) detection, and autotilt modes. For a more detailed
description of weather radar operation, refer to Appendix B and
Honeywell Pub. No. A28--1146--048 for the PRIMUS

EHSI Weather Radar Mode and Target Alert Annunciators
Figure 4--40
D Target Alert Annunciator (All Modes) -- When target alert is
selected on the weather radar controller , a boxed T is displayed at
the location shown in Figure 4--40. If the weather radar detects a
potentially dangerous target within 7.5 of the aircraft heading, but
beyond the displayed weather radar range, the annunciator
changes to a flashing T. In VAR mode, V is displayed in the same
location.
D Range Ring and Annunciator (WX, MAP, and MAP/WX modes
only) -- Range is set using the weather radar controller. One--half
the selected range is annunciated in cyan beside the half--range
ring. If range information is not available, the range default value is
50 NM.
