What is the crosswind component for a Rwy 13 landing when the surface wind is 180° at 25 knots?

Explanation:
To determine the crosswind component when landing on Runway 13 with a surface wind coming from 180° at 25 knots, it is important to first understand the positioning of the runway and the wind direction. Runway 13 is oriented at a heading of 130° (which is approximately 130° clockwise from north). When the wind is coming from 180° (directly south), it is essential to analyze the angle between the runway and the wind direction. The angle of approach can be calculated as follows: 1. Calculate the angle difference between the wind direction and runway heading: - The wind at 180° is directly opposite to Runway 13’s 130°. Thus, the angle to consider for crosswind is: - 180° - 130° = 50°. 2. Now, to find the crosswind component, the formula is used: - Crosswind Component = Wind Speed × sin(Angle). - In this case, it becomes: - Crosswind Component = 25 knots × sin(50°). 3. Using a calculator or sine table, find sin(50°), which is approximately 0.7660. 4. Now, compute the

To determine the crosswind component when landing on Runway 13 with a surface wind coming from 180° at 25 knots, it is important to first understand the positioning of the runway and the wind direction.

Runway 13 is oriented at a heading of 130° (which is approximately 130° clockwise from north). When the wind is coming from 180° (directly south), it is essential to analyze the angle between the runway and the wind direction. The angle of approach can be calculated as follows:

  1. Calculate the angle difference between the wind direction and runway heading:

  • The wind at 180° is directly opposite to Runway 13’s 130°. Thus, the angle to consider for crosswind is:

  • 180° - 130° = 50°.

  1. Now, to find the crosswind component, the formula is used:

  • Crosswind Component = Wind Speed × sin(Angle).

  • In this case, it becomes:

  • Crosswind Component = 25 knots × sin(50°).

  1. Using a calculator or sine table, find sin(50°), which is approximately 0.7660.

  2. Now, compute the
