Which statement about wind shear alerts is correct?

• A. They trigger both a visual and an audible alarm
• B. They trigger only a visual alert
• C. They trigger only an audible alarm
• D. They trigger no alert on the display

Answer: (A)

Wind shear alerts are designed to grab attention quickly by using more than one warning channel. When the system detects conditions consistent with wind shear, it not only flags the crew visually on the cockpit displays (such as a prominent wind shear message or symbol on the PFD/ND) but also gives an audible alarm. This multimodal alert is important because wind shear can cause sudden changes in airspeed and flight path, especially during takeoff or landing, and pilots need to notice and react immediately regardless of where their eyes are in the cockpit. So the statement that wind shear alerts trigger both a visual and an audible alert is the best description.
