What should be done if you encounter Increase Performance Windshear when following an ILS?

In the event of encountering increased performance windshear while following an Instrument Landing System (ILS), the appropriate response is to decrease power and lower the nose. This approach works because increased performance windshear typically means that the aircraft is encountering a sudden change in wind speed or direction that can cause a loss of lift or increased drag. By decreasing power, the aircraft's thrust is reduced, which can help to stabilize the aircraft in a low-lift situation typically caused by windshear.

Lowering the nose helps to maintain or achieve the appropriate angle of attack and can improve airflow over the wings, thereby enhancing the aircraft's lift. This action helps the pilot to regain control and maintain a safe flight profile. Understanding how to counteract the effects of windshear is critical for maintaining safety during approaches, as pilots must respond rapidly to changing conditions to ensure that they can manage the aircraft effectively.

In this scenario, it's important to have knowledge of the relationship between aircraft power settings, control inputs, and how they affect the aircraft's performance in challenging wind conditions.
