Subject:
Predictive Windshear System Anomaly
Reason:
This bulletin informs flight crews of the susceptibility of certain airports
to false Predictive Windshear System (PWS) alerts.
THE FOLLOWING PROCEDURE AND/OR INFORMATION IS EFFECTIVE UPON RECEIPT
Background Information
Airlines have reported a false Predictive Windshear System (PWS) alert at the
Rio de Janeiro airport (SBRJ). The anomaly is only applicable to PWS alerts; all
reactive windshear alerts which occur are valid. These false alerts are limited to
airplanes equipped with the Honeywell weather radar RDR-4000 with the
following PWS weather radar processor part numbers:
• 930-1000-001
• 930-1000-002
• 930-1000-003
Honeywell has reviewed data provided by the affected airlines and has attempted
to determine if particular airports and runways may be susceptible to “false
alerts”. In addition, data have been analyzed to determine if the alerts are more
likely during takeoff or on approach.
Honeywell has accumulated sufficient data to suggest that the following runway
is susceptible to false PWS alerts:
• SBRJ (Rio de Janeiro), Runway 20L, Approach
Although this particular airport appears to be more susceptible to false alerts, the
data indicates the majority of operations at this airport do not experience false
PWS alerts.
Information in this bulletin is recommended by The Boeing Company, but may not be FAA approved
at the time of writing. In the event of conflict with the FAA approved Airplane Flight Manual
(AFM), the AFM shall supersede. The Boeing Company regards the information or procedures
described herein as having a direct or indirect bearing on the safe operation of this model airplane.
