The descent angle relative to the ground will be affected by the wind. So, the descent gradient will be affected as well. A headwind will reduce the ground speed and therefore reduce the horizontal distance that aircraft travels in comparison to the no wind conditions.

What does a headwind do to a plane?

Headwind is wind blowing towards the aircraft. Pilots prefer to land and take off in headwind because it increases the lift. In headwind, a lower ground speed and a shorter run is needed for the plane to become airborne.

How does headwind affect takeoff?

A headwind therefore reduces the ground speed at a required takeoff air speed and reduces the takeoff distance. On the other hand, a tailwind increases the ground speed, at a same required takeoff air speed, and increases the takeoff distance. Crosswind component has no effect on the takeoff distance.
