With a reported wind of south at 20 knots, which runway is appropriate for an airplane with a maximum crosswind component of 13 knots?

To determine which runway is appropriate given a south wind at 20 knots and an airplane's maximum crosswind component of 13 knots, it's important to consider both the wind direction and how each runway aligns with that wind direction.

When the wind is coming from the south, it means that any runway aligned to the north or south will have a headwind and will be less affected by the crosswind component. In this case, a runway that runs east-west will provide the greatest crosswind challenge.

Runway 14, which aligns roughly toward the northeast (140 degrees), is oriented in such a way that it will be subject to crosswinds. With a south wind at 20 knots, the crosswind component would be significant. However, you need to consider the tolerable limits of the aircraft.

The other runway choices, such as Runway 10 (aligned more east-west) and Runway 28 (also oriented east-west), would present a headwind situation, minimizing crosswind effects. Runway 24 is aligned more toward the west and would subject the aircraft to a significant crosswind. Since the airplane's maximum safe limit for crosswinds is 13 knots, Runway 14, which would have the least crosswind component relative
