If winds are 101° at 18 knots, which runway do the winds favor, and what is the crosswind component?

To determine which runway the winds favor and to calculate the crosswind component, it's important to analyze the wind direction and runway orientations.

In this scenario, the wind is coming from 101°, which means the wind is blowing from the east-southeast towards the west-northwest. Runway alignment is usually measured in degrees from magnetic north; therefore, we should evaluate runways aligned to either 16 (160°) or 34 (340°).

Runway 34 is oriented towards 340°, which is roughly into the wind coming from 101°. In that case, the wind would strike this runway at an angle, creating a crosswind. The crosswind component can be calculated using the wind's direction relative to the runway's heading.

By utilizing the wind correction formula, you'll find that the crosswind component for runway 34 is approximately 9 knots, coming from the right side (as the wind is from 101°, and runway 34 faces 340°, thus resulting in a right crosswind).

The option that identifies runway 34 with a 9 knot right crosswind aligns accurately with the direction of winds and their impact on the aircraft direction when approaching or taking off from that runway. This reasoning reinforces
