What term describes a wind blowing in a direction that reduces the ground speed of an airplane in flight?

• A. HOLDING
• B. FORWARD
• C. GROUND POWER UNIT
• D. HEADWIND

Answer: (D)

Headwinds reduce ground speed because ground speed is how fast you move over the ground, which is the combination of your airspeed and the wind component along your flight path. When the wind blows from ahead, it pushes against you, so with a given airspeed you cover less ground each minute. A tailwind would do the opposite, increasing ground speed. Crosswinds affect your track and require heading adjustments but don’t inherently reduce ground speed along your intended direction. The other terms are unrelated to wind direction: holding is a maneuver to delay or stay in a pattern, and a ground power unit is equipment used on the ground.
