If the wind at the surface is reported at 260 degrees at 20 knots, what is the crosswind component while landing on runway 30?

To determine the crosswind component while landing on runway 30, which is oriented at a heading of 300 degrees, we first need to analyze the wind direction and speed. The wind is reported to be coming from 260 degrees at 20 knots.

To find the crosswind component, we need to calculate the angle between the runway and the wind direction. Since the wind is from 260 degrees and the runway is oriented at 300 degrees, we can find the difference:

• The angle between the wind and the runway is 300 - 260 = 40 degrees.

Knowing this angle, we can use the sine function to calculate the crosswind component, which is defined as the wind speed multiplied by the sine of the angle between the wind direction and the runway heading.

Crosswind Component = Wind Speed × sin(angle)

In this case, the wind speed is 20 knots, and the angle is 40 degrees. First, we calculate the sine of 40 degrees, which is approximately 0.6428.

Now we perform the calculation:

Crosswind Component = 20 knots × sin(40 degrees) ≈ 20 knots × 0.6428 ≈ 12.856 knots.
