Flight Crew Operations Manual Bulletin No. GOT-12 , Dated October 22, 2018 (continued)
Flight crews should use the following criteria to help determine if windshear
exists:
• reports of windshear from other aircraft
• visual indications
• tower windshear alerts
• differences between computed winds in the airplane and reported winds
from the tower.
As Honeywell continues to develop a software solution and to process data,
operators are encouraged to continue reporting incidents to Honeywell and
Boeing in order to provide the most effective solution possible to this anomaly.
Operating Instructions
If windshear is encountered, perform the Windshear Escape Maneuver.
It is recommended operators establish policies for flight crews operating into the
reported runway in the event a PWS alert occurs. The following windshear
criteria may be beneficial in establishing policies:
• reports of windshear from other aircraft
• visual indications
• tower windshear alerts
• differences between computed winds in the airplane and reported winds
from the tower.
