What is the headwind component multiplier for a wind angle of 060 degrees relative to the runway?

• A. 1.0
• B. 0.0
• C. 0.5
• D. 0.7

Answer: (C)

The headwind component is found by projecting the wind onto the runway direction, which means multiplying the wind speed by the cosine of the angle between the wind direction and the runway. With a wind angle of 60 degrees, cos(60°) = 0.5, so the headwind multiplier is 0.5. In other words, the headwind component is half the wind speed. The other options correspond to angles: 0° gives a full headwind (1.0), 90° gives no headwind (0.0), and around 45° gives about 0.7.
