Tail Wind refers to wind blowing in which direction relative to the airplane's travel, and what is its effect on ground speed?

• A. Preflight Inspection
• B. Unaccompanied Minor (UMNR)
• C. Round Trip
• D. Tail Wind

Answer: (D)

Tail wind means the wind is blowing from behind the airplane, pushing it along its path. This adds to the forward motion, so ground speed increases (ground speed = airspeed plus the wind component along the flight path). For example, with an indicated airspeed of 150 knots and a 20-knot tailwind, the ground speed would be about 170 knots. The airspeed indicator doesn’t change due to wind; it’s the ground speed that goes up when there’s a tailwind. Tailwinds can shorten flight time but also affect takeoff and landing performance due to higher ground speeds during those phases.
