Which of the following wind conditions is most suitable for landing on Runway 10 for an aircraft with a maximum crosswind component of 15 knots?

When considering suitable wind conditions for landing on a specific runway, it is essential to evaluate the wind direction and strength in relation to the aircraft's maximum crosswind component. In this scenario, the aircraft has a maximum crosswind component limitation of 15 knots.

Landing on Runway 10 indicates that the aircraft will be approaching from the east, as Runway 10 is oriented approximately 100 degrees. The most favorable wind direction for this approach would be from directly ahead (or slightly angled) to minimize crosswind effects.

A wind from 180° at 10 knots creates a tailwind, which is generally not ideal for landing, but it doesn't generate a crosswind component since it's coming directly from behind. Although it's not a strong crosswind, it's still safer than facing a crosswind higher than the maximum limit.

In contrast, a wind from 050° at 20 knots presents a significant crosswind of about 15 knots, which is right at the maximum acceptable limit, potentially making the landing challenging. A wind from 100° at 15 knots would not create a crosswind situation per se, but it does indicate a headwind component, which is beneficial for landing. However, it's also critical to ensure the approach isn't directly contested
