Which combination of statements is accurate in the presence of an aircraft experiencing wind shear?

In the context of wind shear, particularly during approach and landing, the situation involves abrupt changes in wind velocity and direction, which greatly affect the aircraft's performance and handling. When an aircraft is experiencing wind shear, the most accurate scenario is when it flies below the glide path and has a decreasing true airspeed.

When an aircraft is below the glide path, it indicates that the aircraft's altitude is lower than where it should ideally be to maintain the correct descent profile toward the runway. Wind shear can cause a decrease in airspeed due to a sudden loss of lift or a headwind, which can be a critical factor in this scenario. As the true airspeed decreases, the aircraft may not maintain sufficient lift to continue its descent safely, necessitating effective management by the pilots to avoid potential loss of control or stall.

In this case, pilots must be highly vigilant, as the combination of being below the glide path and experiencing decreasing true airspeed increases the risk of not being able to land safely, calling for immediate corrective measures such as increasing power or adjusting the pitch to recover.

The other scenarios presented do not align with the typical dynamics of wind shear. For instance, an aircraft flying above the glide path would more likely be in a climb or level
