Introduction

The Airbus 320 aircraft is equipped with an X-band weather radar system which also has Predictive Windshear capability.

This system complies with the ARINC Characteristics 708A.

The Airbus 320 Weather Radar system can

1. Detect atmospheric disturbances in the area defined by the antenna scanning: plus or minus 90 deg. of aircraft center line and up to 320NM in front of the aircraft.

2. Detect turbulence areas up to a distance of 40NM.

3. Presentation of terrain mapping information

4. If the Predictive Windshear System is operative

   1. Microburst windshear event in the area defined by the antenna scanning: plus or minus 60 deg.

   2. Windshear events within an area plus or minus 30 deg. of aircraft center line and up to 5NM in front of the aircraft.

The weather radar and windshear detection image (if the predictive windshear function is activated) is shown on the Captain and First Officer Navigation Displays (ND)

The windshear warning is shown on Captain and First Officer Primary Flight Displays (PFD) and on the upper ECAM DU.
