CONTROLS
The following features are modeled respectively can be operated in the Aerosoft A318/319/A320/A321:
• GAIN (-15<>+15): Sets the sensitivity of the receiver.
• MULTISCAN (MAN and AUTO): Multiscan mode is in Auto, off in Man.
• GCS (OFF and AUTO): Ground Clutter Suppression.
• TILT ( -15° <> +15°): Controls the pitch of the radar transmitter.
• Range control: Range control is set by the standard Navigation Display Range setting.
Whereas the range control is handled on the EFIS for the other settings the WXR panel is used. To get the
maximum range / display it is necessary to have set SETTINGS / WEATHER / CLOUD DRAW DISTANCE to
the maximum (if a weather tool is used apply the same settings to it).
WEATHER RADAR DISPLAY
The weather radar display is depicted on the ND in any mode except PLAN. The selected ND range scale
will control the weather radar range.
The radar returns will appear in black, green, yellow, red or magenta depending on the precipitation
intensity. The antenna tilt angle will be displayed in the lower right-hand corner of the ND and is the angle
between the horizon and the radar beam axis. When MULTISCAN manual calibration mode is selected,
MAN and the setting appear in blue whereas in AUTO mode the setting appears in green.
If the TERR ON ND is selected on, the ND displays the surrounding terrain from the stored database, and
the weather radar display will be suppressed.
OPERATION
In standard operation the weather radar is kept in automatic multiscan mode and will always use the
most suitable tilt angle for the current flight stage. These optimized settings are a good reference for
manual mode.
