When landing runway 22 with winds from 140 degrees at 20 knots, what is the crosswind component?

To determine the crosswind component when landing on runway 22 with winds coming from 140 degrees at 20 knots, it is essential to first establish the relationship between the wind direction and the runway heading. Runway 22 is oriented at 220 degrees.

When analyzing the wind direction, a wind from 140 degrees means it is coming from the southeast (140 degrees) and blowing towards the northwest. To find the crosswind component, we determine the angle difference between the wind direction and the runway direction. The difference between 140 degrees and 220 degrees is 80 degrees.

The next step is to calculate the crosswind component using the formula:

Crosswind Component = Wind Speed × sin(angle)

In this case, the wind speed is 20 knots and the angle between the wind direction and the runway is 80 degrees:

Crosswind Component = 20 knots × sin(80 degrees)

Calculating this gives approximately 19.4 knots, which we can round to 20 knots for simplicity. Since the wind is coming from the right relative to the runway, this creates a left crosswind.

Thus, since the calculated crosswind is significant and originates from the right, landing on runway 22 with winds from 140 degrees at
