What should the pilot expect regarding airspeed and glide slope when a headwind transitions to a tailwind?

When a pilot experiences a transition from a headwind to a tailwind during an approach, it has a significant impact on airspeed and pitch attitude. The correct choice indicates that airspeed decreases, pitch attitude decreases, and the aircraft has a tendency to go below the glide slope.

This situation occurs because when a tailwind is encountered, it increases the groundspeed of the aircraft while the indicated airspeed may decrease. A lower indicated airspeed can lead to a reduction in lift, and the pilot may find themselves needing to adjust the pitch attitude to maintain an appropriate descent path. If the pilot does not compensate for this change, the aircraft might start to descends below the desired glide slope.

In essence, transitioning to a tailwind can make the aircraft behave differently than expected, particularly by reducing the airspeed which could lead to inadequate lift and potential deviation from the approach path if corrective action is not taken.
