What crosswind component is observed if landing on a specific runway with winds from 180 degrees at 25 knots?

When considering wind direction and its effect on landing, it's essential to visualize how the wind interacts with the runway. In this scenario, the wind is blowing from 180 degrees, which means it's coming from directly south, while the runway is oriented in a particular direction. The crosswind component is determined by calculating the wind's influence perpendicular to the centerline of the runway.

To find the crosswind component when the wind is blowing directly from 180 degrees at 25 knots, the formula to determine the crosswind is to multiply the wind speed by the sine of the angle between the wind direction and the runway orientation. If the runway is aligned perfectly with the wind (for example, a runway heading of 360 degrees or 180 degrees), there would be no crosswind effect.

If the runway were aligned along the north-south axis (for instance, runway 36 or 18), the wind would create a maximum crosswind scenario at 90 degrees to the runway centerline. When calculating the crosswind for other runway headings, the wind component adjusts based on the angle the wind is offset from the runway heading.

In this question, if it's assumed that the runway is oriented 90 degrees to the wind direction (for instance, a runway heading
