LAHSO acceptance prohibits tailwinds exceeding how many knots?

• A. +3 knots
• B. +5 knots
• C. 0 knots
• D. -3 knots

Answer: (A)

LAHSO operations require enough runway margin to safely land and stop before the hold-short point. A tailwind increases landing distance and reduces that margin, making it harder to stop in time. To keep safety margins, the tailwind component must not exceed 3 knots. That means a tailwind of up to 3 knots is allowed, while higher tailwinds are not. A headwind (negative tailwind) or zero tailwind is acceptable, which is why the limit is stated as 3 knots of tailwind.
