WebMay 21, 2024 · When you're dealing with a gusty day, the FAA recommends that you add half the gust factor to your final approach speed. For example, if the winds are reported at 18 knots, gusting 30 knots, it means you have a gust factor of 12 knots (30-18 = 12). So if you take half the gust factor, you get 6 knots (12/2 = 6). Yes, it's math, but it's really ... Web1.3.2.
