What wind condition is described for the takeoff scenario?

• A. Crosswind angle of ±30 degrees with 30 knots windspeed
• B. Crosswind angle of ±15 degrees with 20 knots windspeed
• C. Headwind of 30 knots
• D. Tailwind of 30 knots

Answer: (A)

Takeoff wind conditions hinge on how the wind direction relates to the runway. The described scenario is wind coming from the side, offset from the runway by as much as 30 degrees, with a speed of 30 knots. That makes it a crosswind condition, not a headwind or a tailwind. The crosswind component is the part of the wind blowing across the runway, roughly 30 knots × sin(30°) = 15 knots here, while the headwind component is the part blowing along the runway, about 30 knots × cos(30°) ≈ 26 knots. So you’ve got a substantial crosswind while still retaining a notable headwind component. The other options describe winds directly along or opposite the runway or a smaller crosswind, which don’t match the described takeoff scenario.
