How does a headwind affect an airplane's ground distance in a power-off glide?

A headwind reduces ground distance.

  1. It increases ground distance
  2. It reduces ground distance ✔
  3. It has no effect on distance

Why: At a given glide airspeed, a headwind lowers groundspeed. The airplane therefore covers less ground before using the available altitude.

Huh, didn't know that: A tailwind increases glide distance over the ground by increasing groundspeed.

The dad joke
The headwind shortened the trip without moving the destination closer.

    With a tailwind, the airplane glides farther because of the higher groundspeed. Conversely, with a headwind, the airplane does not glide as far because of the slower groundspeed.
