What is the approximate crosswind component when landing on Rwy 03 with a wind from 060° at 35 knots?

• A. 30 knots
• B. 18 knots
• C. 25 knots
• D. 15 knots

Answer: (B)

To determine the approximate crosswind component when landing on Runway 03 with a wind from 060° at 35 knots, it is crucial to understand how to calculate crosswind components based on the angles involved.

Runway 03 is oriented at 030° magnetic. When the wind is coming from 060°, it means the wind is approaching from the east-northeast. To find the crosswind component, we need to calculate the angle between the runway heading and the wind direction.

The angle between 060° and 030° can be calculated as follows:

• Subtract the runway heading from the wind direction: 060° - 030° = 30°.

Next, to find the crosswind component, you can use the formula:

Crosswind = Wind Speed × sin(angle)

In this case:

• Wind Speed is 35 knots,

• The angle calculated is 30°.

Using the sine function:

• sin(30°) = 0.5,

• Crosswind = 35 knots × 0.5 = 17.5 knots.

Rounding to the nearest significant figure gives approximately 18 knots, aligning closely with the choice provided.

Thus, the calculated crosswind component for landing
