Regarding gust factor adjustments at 500 ft HAT, which statement is true?

• A. Gust factor adjustments apply to altimeter settings
• B. Gust factor adjustments are not considered for airspeed
• C. Gust factor adjustments apply only to vertical speed
• D. Gust factor adjustments apply to approach airspeed as required

Answer: (D)

Gust factor is used to adjust your approach airspeed to account for gusts so you maintain a safe margin against stall and energy loss in gusty winds near the ground. At 500 ft HAT, during the approach, you apply this gust factor to the target approach speed you plan to fly. This makes your indicated airspeed higher than the calm-weather target, as required by SOP or the gust factor in effect, to stay ahead of gust-induced airspeed fluctuations. This adjustment is not applied to altimeter settings—pressure settings affect the altitude readout, not gusts. It’s also not a change to vertical speed itself; the vertical speed response comes from pitch and thrust while airspeed is adjusted to handle gusts. So adjusting approach airspeed as needed by the gust factor correctly reflects how gusts are managed during the approach.
