A fellow pilot says he prefers landing with a tailwind on wet runways because the reduced ground speed gives better braking traction. How would you respond?
Your answer
"That's wrong. A tailwind increases your groundspeed, not decreases it. You should always land into the wind because it gives you a shorter landing distance."
You correctly identified that a tailwind increases groundspeed, not decreases it, and that landing into the wind gives a shorter landing distance. [PHAK p.273] However, you missed the most critical reason on a wetrunway: higher groundspeed increases hydroplaning risk. Once hydroplaning starts, "braking and directional control are almost nil." [PHAK p.269] You should also mention that a headwind improves directional control on wet surfaces [AFH p.135] and that a 10-knot tailwind increases landing distance by approximately 21%. [PHAK p.273]
