What is the recommended first action upon recognizing windshear?

Upon recognizing windshear, the recommended first action is to announce "WINDSHEAR" to the crew. This immediate communication is crucial because it alerts all crew members of the potential hazard, facilitating a coordinated response and enhancing situational awareness. Recognizing windshear is critical for flight safety, and timely announcements can help ensure that everyone is prepared to take necessary actions promptly.

Communicating the presence of windshear ensures that all crew members are aware and can focus on managing the aircraft appropriately to counteract its effects. It promotes a shared awareness that is essential in high-stress situations, thereby reinforcing the need for teamwork and effective communication in managing emergencies.

Other actions, while important, should follow the immediate announcement. For example, cross-checking airspeed indicators and altimeters can provide essential data, but it does not replace the need for prompt communication with the crew. Likewise, reducing power or selecting speed hold may be appropriate responses, but they should occur after ensuring that everyone is aware of the situation. Thus, the correct choice emphasizes the importance of communication in managing windshear effectively.
