What is a potential tailwind component during an approach when wind direction is 220° at 10 knots before landing on runway 28?

To determine the potential tailwind component during the approach for landing on runway 28, we need to analyze the wind direction in relation to the runway's heading. Runway 28 has a heading of 280 degrees (since runways are named based on their magnetic heading rounded to the nearest ten degrees).

In this case, the wind is coming from 220 degrees at 10 knots. The tailwind component is calculated by finding the angle between the runway heading (280 degrees) and the wind direction (220 degrees).

The wind is coming from the southwest (220 degrees), while the aircraft is approaching from the west (280 degrees). The angle difference between these two directions is 60 degrees (as a tailwind would be when the wind comes from behind the aircraft).

To find the tailwind component, you can use the cosine of the angle difference with respect to the wind speed:

Tailwind component = Wind speed × cos(angle)

For a 60-degree angle, cos(60°) equals 0.5. Thus:

Tailwind component = 10 knots × 0.5 = 5 knots.

Therefore, the potential tailwind component during the approach in this scenario is 5 knots. This reasoning confirms that the
