What term describes the wind experienced by an aircraft in flight, relative to its direction of motion?

• A. Headwind
• B. Relative Wind
• C. Tailwind
• D. Ground Wind

Answer: (B)

The wind the airplane actually feels as it moves through the air is called the relative wind. It’s the airflow that moves past the aircraft, and its direction is generally opposite the aircraft’s motion through the air. This relative wind comes from the combination of the aircraft’s speed through the air and any ambient wind blowing around it, so it’s what the wings and other surfaces “see” when generating lift. Headwinds and tailwinds describe wind relative to the ground, not the air’s motion past the aircraft, so they don’t fully capture what the aircraft experiences in flight. Ground wind is simply wind measured at the surface, unrelated to how fast or in what direction the plane is moving through the air.
