Under the Two Hour Island Reserve rule, what is the maximum crosswind component including gust allowed?

• A. 20 kts
• B. 30 kts
• C. 15 kts
• D. 25 kts

Answer: (D)

Crosswind allowance includes gusts, and for Two Hour Island Reserve operations the limit is 25 knots. In practice, you add the gust component to the sustained crosswind to get the total crosswind including gust; if that total would exceed 25 knots, the operation isn’t authorized. For example, a sustained crosswind of 20 knots with gusts of 5 knots reaches the limit (20 + 5 = 25). If gusts reach 6 knots, the total would be 26 and would not be allowed. Therefore, the maximum crosswind component including gust allowed is 25 knots.
