The weather radars have a predictive windshear capability.
The Predictive Windshear System (PWS) operates when :
- The PWS switch is in the AUTO position, and
- The aircraft is below 2300 feet AGL, and
- The ATC is switched to the ON, or AUTO, position, and
- Either engine is running.
The system scans the airspace, within a range of 5 NM ahead of the aircraft, for
windshears. Below 1500 feet, when the system detects windshear, depending on the range
selected on the ND, a warning, caution, or advisory message appears on the ND. Predictive
windshear warnings and cautions are associated with an aural warning.
Windshear alert ranges, altitudes, and locations, for the three alert levels are indicated
below:
During the takeoff roll, both warnings and
At takeoff, alerts are inhibited above 100
At landing :
cautions are available within a range of 3 NM
knots and up to 50 feet.
Alerts are inhibited below 50 feet.
The visual and aural warning alerts are downgraded to caution alerts between 370 feet
AGL and 50 feet AGL, and range between 0.5 NM and 1.5 NM.
R Note : If the selected weather radar fails when two weather radars are installed, the PWS
R function is recovered by selecting the non-failed weather radar on the control panel
