Description

The A320 is fitted with a weather radar system which includes a Predictive Windshear System (PWS) and a weather hazard prediction function.

The weather radar data can be displayed on the NDs in ARC or ROSE mode.

Usage

Radar

• ON:
  • Set the switch to position 1 or 2 to turn on system 1 or 2.
• OFF:
  • Set the switch to position OFF (middle) to turn off the system.

GAIN

• This knob adjusts the sensitivity of the radar.

MODE - Display mode selector

• WX:
  • Weather mode: Intensity of precipitation (black for the lowest intensity, green, amber and red indicate progressively higher intensity).
• WX+T:
  • Weather and Turbulence mode: WX plus turbulence areas are displayed in magenta.
• TURB:
  • Turbulence mode: Only turbulence areas.
• WX+T+HZD:
  • Weather, Turbulence and Hazard mode (recommended position): WX+T and hazard prediction risk areas
• MAP:
  • Map mode: No weather display but ground information: Black for water, green for ground, and amber for cities and mountains.

TILT

This allows tilting the radar antenna when MULTISCAN is MAN. Zero uses the horizon reference from the IRS.

MULTISCAN

• AUTO:
  • Controls radar antenna tilt automatically combining two scans from different angles to optimize weather detection and minimize ground clutter.
• MAN:
  • Manually adjust radar antenna tilt using the TILT knob.

GCS (Ground Clutter Suppression)

• AUTO:
  • Normal radar use if MULTISCAN is on AUTO. Ground Clutter is not displayed.
  • GCS has no utility if MUTLISCAN is on MAN. Ground clutter is visible.
• OFF:
  • Ground clutter is visible.

PWS

• AUTO:
  • Predictive WindShear is on when condition are met.
• OFF:
  • The Predictive WindShear function is off.
