Hazard Awareness
VERTICAL SCAN
FEATURE LIMITATIONS
•
Vertical scan not available on RS 181A and RS 811A radars
For a more accurate view of target coverage and intensity, center the tilt angle
on the strongest return area, aiming below the freezing level of the storm.
In areas of multiple heavy cells, use the vertical scan feature along with antenna
tilt to examine the cells. Avoid shadowed areas behind targets.

Tilt Line Vertical scans focus the radar on a
particular vertical target.
Vertical Scan with Stabilization
When vertically scanning with
stabilization on, the physical area
that the radar is sweeping may
not match the displayed vertical
scan. This occurs when the
aircraft pitch is not at 0°. To
compensate, the GDU does not
draw the unscanned portion.
To avoid constant adjustment of
the bearing line, ensure that the
aircraft wings are level when
performing a vertical scan of a
storm cell.
