Turbulence Detection - Honeywell IntuVue RDR-4000 Pilot's Manual

IntuVue RDR-4000 Weather Radar Pilot's Guide

TURBULENCE DETECTION

Turbulence detection is an automatic function of this weather radar
system.
For turbulence detection and
evaluation use the following
procedure:
1. System Control: L or R (or
NORM for single system)
2. Mode: AUTO (also
available in MAN mode if
the Hazard Display
Configuration is installed)
3. Range: As desired.
Turbulence information is limited to the first 40 nm (60 nm if the Hazard
Display Configuration is installed). Turbulence within this range and
inside the Flight Path Weather envelope will be displayed in magenta.
The turbulence data is represented in a blocky shape, helping to visually
differentiate it from reflectivity data.
The turbulence detection feature of the RDR-4000 is quite sensitive as
compared to previous radar functionality. The threshold for displaying
indications of turbulence is based on the potential aircraft response to
that turbulence. Therefore, magenta blocks may be displayed on top of
any color, including black.
If the Hazard Display Configuration of the radar system is installed, the
GAIN knob can be used to temporarily suppress the display of Hazard
Icons and Turbulence Indication. See HAZARD DISPLAY
SUPPRESSION on page 29 for details.
