If you encounter windshear after passing the final approach fix, what should you do?

When encountering windshear after passing the final approach fix, it is crucial to promptly report the situation to the most appropriate agency. This action is important for safety as it allows air traffic control and other aircraft in the vicinity to be aware of potentially hazardous conditions. Reporting windshear helps to disseminate information regarding unsafe weather phenomena, which could impact other aircraft approaching or departing from the runway. Additionally, this communication can lead to real-time guidance from ATC, ensuring that you're following the safest procedures during the encounter.

Continuing the approach with caution may be tempting, but without awareness of windshear conditions, it could lead to serious safety risks. Climbing to a higher altitude may not be feasible or beneficial once you are already in the approach phase, and executing a go-around might be necessary in some situations, but informing authorities about the windshear should take precedence to alert others of the danger.
