Given winds of 180° at 25 knots and an airport with runway 03/21, which runway do the winds favor and what is the crosswind component?

To determine the favored runway based on the wind direction and speed, we need to analyze how the winds affect the runways available at the airport, which are oriented at 03/21 degrees.

The given wind is from 180 degrees at 25 knots. This means the wind is coming from directly south. To evaluate the runways:

1. Runway 21 (210 degrees) is aligned almost directly into the wind, meaning the wind will be mostly tailwind or headwind when approaching from this direction. However, since it aligns with the wind coming from the south, the crosswind component can still be calculated.

2. Runway 03 (30 degrees) is aligned 180 degrees opposite to Runway 21. Since it is positioned in a direction (north) opposite to the wind coming from the south, it will experience a significant crosswind.

When calculating the crosswind component for each runway, the formula can be applied, which involves finding the angle between the wind direction and the runway heading. This angle determines how much of the wind acts as a crosswind.

For Runway 21:

• The angle between the wind (180) and the runway (210) is 30 degrees
