Windshear Annunciation (WDSHEAR)
-- When the windshear
detection system detects windshear, this annunciator flashes for 10
seconds and then goes on steadily. Depending on the severity of the
windshear detected, the annunciator can be amber or red. If the GA
button is pushed during a windshear caution or warning, the FD
vertical mode becomes windshear (WSHR) and vertical FD
guidance directs the aircraft.
