What should pilots do in the event of reporting an encounter with windshear?

Making an immediate report to Air Traffic Control (ATC) following an encounter with windshear is essential for several reasons. First, windshear can pose significant risks to aircraft performance and safety, including abrupt changes in altitude and airspeed. By reporting the encounter to ATC, pilots alert the controlling authority to the hazard, allowing them to relay critical information to other aircraft in the vicinity.

This immediate reporting ensures that ATC can provide timely assistance, which might include issuing warnings to other pilots about the windshear conditions, adjusting traffic patterns, or offering alternative routing to avoid the area of concern. Furthermore, accurate and prompt communication facilitates coordinated responses among emergency services if the situation escalates.

While the other choices may seem relevant in managing the situation, they do not address the critical need for communication with ATC to ensure the safety of all flights in the area.
