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: 1 or 2 (dual system) or 1 (single system)
2. Turb Switch: AUTO or
Turb Pushbutton: Engaged
3. Mode: ALL/ALL WX or
ON PATH/ PATH WX
4. 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 turbulence envelope will be displayed in magenta.
The turbulence data is represented in a blocky shape, helping to
visually differentiate it from reflectivity data. If required, the display of
turbulence information may be turned off by setting the Turbulence
Select Switch to OFF, or by disengaging the Turbulence Pushbutton.
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.
