What signal should be given to the crew when windshear is detected?

When windshear is detected, the appropriate signal to give to the crew is to announce "WINDSHEAR." This announcement serves as an immediate alert to everyone in the cockpit about the potential hazards associated with windshear conditions. Recognizing windshear is critical as it can lead to sudden changes in airspeed and altitude, significantly affecting the aircraft's performance and handling characteristics.

By announcing "WINDSHEAR," the pilot ensures that all crew members are aware of the situation, allowing them to take necessary actions in a timely manner, such as preparing for potential adjustments in flight attitude and speed to counteract the effects of windshear. This prompt communication enables the crew to work together effectively to manage the aircraft safely through critical conditions.

Other choices, while they may seem relevant under different circumstances, do not effectively communicate the urgency and seriousness of the situation that windshear presents. For instance, maintaining the current flight profile might not address the immediate dangers posed by windshear, and initiating a descent or requesting an immediate landing may not be the most effective immediate response without awareness of the windshear event. Hence, announcing "WINDSHEAR" is crucial for ensuring that all crew members are on the same page regarding the unfolding
