Tail wind is defined as a wind that has which principal effect on a flying aircraft?

• A. Advances the ground speed of an airplane in flight
• B. Slows the aircraft down on approach
• C. Causes turbulence
• D. Reduces fuel efficiency

Answer: (A)

Tailwind means a wind blowing from behind the airplane. The main effect is to increase the aircraft’s ground speed because the wind adds to the forward motion relative to the ground. In other words, your speed over the ground goes up while the airspeed (the speed of the airplane through the air) stays the same unless you change thrust or attitude. This is why a tailwind helps you cover distance faster. It doesn’t slow you on approach, it doesn’t by itself cause turbulence, and it doesn’t inherently reduce fuel efficiency—the standout effect asked about is the faster ground speed.
