Weather Radar Alert Mode
When active by the WX configuration (during weather radar
installation), the KSN 765/770 can provide a target alert annunciation
during horizontal scan when the weather mode is WX.
NOTES: 1. A target alert is not provided during vertical scan.
2. Target alert is only applicable for RDR 2000 and
RDR 2100 installations.
Target alert is a feature that provides warning of potential severe
weather in the flight path that is detected beyond the current range
displayed.
The criteria for a target alert is for the cell to be at least red intensity,
within 10_ of aircraft heading, a minimum size of 2 NM in range and
2 degrees in azimuth, and within the range of 80 to 320 NM. When a
target alert is issued, two red arcs, separated by a black arc will be
displayed at the top of the display centered on the aircraft heading.
Target Alert is applied to each scan independent of the other when the
radar is alternating scans.
When an alert condition exists, two red arcs separated by a black arc
are displayed at the top of the display centered on the aircraft heading,
as shown in Figure 11--4.
