How much should the final approach speed increase with a wind reported at 10 knots gusting to 18 knots?

In order to determine the increase in final approach speed due to wind conditions, it is essential to consider the effect of wind on aircraft performance during the landing phase. A headwind can reduce your required approach speed, while a tailwind can increase it. In this scenario, the wind is reported as 10 knots gusting to 18 knots, indicating that there is a variable wind component that must be accounted for.

When calculating the necessary adjustments for gusting winds, pilots typically increase their final approach speed to maintain control and ensure adequate handling characteristics as wind conditions vary. The standard guidance for adding speed for gusting winds suggests using 50% of the difference between the steady wind and the gusting wind to account for the fluctuation.

Here, the steady wind is 10 knots and the maximum gust is 18 knots, creating a differential of 8 knots. Thus, taking 50% of this 8-knot difference leads to an increase of 4 knots in the final approach speed to compensate effectively for the gusting.

Therefore, an increase of 4 KIAS is the appropriate amount to ensure safe handling during the landing process under the given wind conditions. This reasoning aligns with best practices in aviation for managing approach speeds in gusty
