 WEATHER RADAR SYSTEM - DESCRIPTION AND OPERATION
________________________________________________
 1. General
_______ The aircraft is equipped with an X-band weather radar system with Predictive Windshear capability. This system complies with the ARINC Characteristics 708A. The weather radar system enables:
 -
detection and localization of the atmospheric disturbances in the area defined by the antenna scanning: plus or minus 90 deg. of aircraft centerline and up to 320NM in front of the aircraft,

 -
detection of turbulence areas caused by the presence of precipitations up to a distance of 40NM,

 -presentation of terrain mapping information by the combination of the orientation of the radar beam and of the receiver gain,
 -detection, if the Predictive Windshear System is operative, of a microburst windshear event in the area defined by the antenna scanning: plus or minus 60 deg.
 -presentation, if the Predictive Windshear System is operative, of
 windshear events within an area plus or minus 30 deg. of aircraft
 centerline and up to 5NM in front of the aircraft.

 NOTE : A microburst is a cool shaft of air, like a cylinder, between 1000
____ and 3000 ft. When it encounters the ground (airflow velocity from 40 to 110 kts) the downward moving airflow is translated to a horizontal flow (from 80 to 220 kts), at the base of the air shaft. Two types of microburst exist, wet and dry.
 Five color displays are used to show precipitations, turbulence and ground mapping to the crew. The location of the windshear events, if the Predictive Windshear System is operative, is indicated by an icon (symbol consisting of alternating red and black arcs).
