Slope Landing Wind Limitations specify a wind correction rate per every 5 knots; how many degrees is the correction?

• A. Minus 1 degree for every 5 knots
• B. Plus 2 degrees for every 5 knots
• C. Minus 3 degrees for every 5 knots
• D. Minus 2 degrees for every 5 knots

Answer: (D)

When performing slope landings, you compensate for crosswind by applying a wind correction angle that scales with wind speed. The wind correction rate for this scenario is 2 degrees of correction for every 5 knots of wind, and the minus sign shows the direction you must move into the wind to cancel drift. So the correction becomes negative two degrees per five knots; for example, a 10-knot crosswind requires about -4 degrees of correction, a 15-knot crosswind about -6 degrees, and so on. This keeps the helicopter from drifting sideways and helps you stay aligned with the slope during the landing.
