DESCRIPTION
Applicable to:
The aircraft has one weather radar system capable of windshear prediction.
It can display the weather image on the ND, in any ND mode except PLAN.
Each pilot may remove the weather image from their ND, by setting the associated brightness control
to the minimum (Refer to DSC-31-50 OTHER EFIS CONTROLS).
DESCRIPTION
Applicable to:
,
,
MSN,,,
The aircraft has two weather radar systems. Only one receiver in working at a time.
It can display the weather image on the ND, in any ND mode except PLAN.
Each pilot may remove the weather image from their ND, by setting the associated brightness control
to the minimum (Refer to DSC-31-50 OTHER EFIS CONTROLS).
Note: Some aircraft may be fitted with one weather radar only.

CONTROL PANEL
Applicable to:
(1) SYS toggle switch
This switch turns the radar ON or OFF.
(2) GAIN knob
Adjusts the sensitivity of the receiver in all modes.
AUTO : Automatically adjusts the gain to the optimum setting.
Note: In windshear mode, GAIN is not adjustable and is automatically controlled. The
weather mode still operates in accordance with GAIN selected on the control panel.
(3) Mode selector
WX : Weather mode : colors indicate the intensity of precipitation (Black indicates
the lowest intensity. Green, amber and red indicate progressively higher
intensities).
WX / TURB : The screen shows turbulence areas (in precipitation areas) in magenta (within
40 nm).
MAP : The radar operates in ground mapping mode. Black indicates water. Green
indicates the ground and Amber indicates cities and mountains.
(4) TILT knob
This knob controls antenna tilt. Zero represents the horizon as ADIRS 1 sees it (or ADIRS 3 if
ATT HDG selector is at CAPT 3).
(5) WINDSHEAR switch (only operative, if the predictive windshear function is installed)
AUTO : Activates the predictive windshear function. Windshear areas are detected by
antenna scanning below 2 300 ft RA, even if the SYS switch is set to OFF. They
are displayed on the ND, if below 1 500 ft.
