To determine the crosswind component when landing on runway 22 with wind coming from 140 degrees at 20 knots, it is essential to analyze the wind direction and runway alignment. Runway 22 is oriented approximately 220 degrees, meaning that a wind from 140 degrees is blowing towards the runway at an angle.

To find the crosswind component, use the formula for calculating wind components:

  1. Calculate the angle between the wind direction and the runway heading. The difference between 220 degrees (runway heading) and 140 degrees (wind direction) is 80 degrees.

  2. Use the sine function to calculate the crosswind component:

  • Crosswind component = wind speed × sin(angle)

  • In this case: Crosswind component = 20 knots × sin(80 degrees).

The sine of 80 degrees is significantly high (close to 1), leading to a substantial crosswind component.

When calculated, the crosswind component comes out to be approximately 20 knots, indicating that the wind will have a left crosswind effect on the aircraft because the wind is coming from the left side (140 degrees is to the left of the runway heading of 220 degrees).

Thus, identifying and correctly assessing the left cross
