Wind blowing in the same direction the airplane is traveling, thus increasing the ground speed.

• A. Tail Wind
• B. Round Trip
• C. Head Wind
• D. Cross Wind

Answer: (A)

The key idea is how wind affects ground speed. Ground speed equals your true airspeed plus the wind component along the flight path. A tailwind is wind blowing from behind, in the same direction you’re traveling, so it adds to your forward motion. That makes ground speed higher than your airspeed, meaning you cover more ground each hour and reach your destination sooner. For example, with a true airspeed of 180 knots and a 20-knot tailwind, your ground speed would be about 200 knots.

A headwind would do the opposite, subtracting from your ground speed and slowing you down. A crosswind comes from the side and doesn’t increase forward ground speed in the same way (it mainly causes drift and requires a heading or crab angle to stay on course). The option about a round trip isn’t about wind direction at all.
