Exemption 17203 is not applicable when which weather conditions are present?

• A. The exemption is not applicable if the weather is: Below 4000 RVR or 3/4sm AND Crosswind >15 knots AND Braking action less than good (RCC less than 5)
• B. The exemption is applicable whenever RVR > 4000
• C. The exemption applies only when crosswinds are >25 knots
• D. The exemption is not applicable if the weather is: Above 4000 RVR or 1/2 sm AND Crosswind >10 knots AND Braking action good

Answer: (A)

Exemption 17203 is not applicable only when all three adverse weather factors line up together. You must have runway visibility below 4000 RVR (or less than 3/4 statute mile), crosswinds greater than 15 knots, and braking action less than good (RCC under 5) for the exemption to be ruled out. If any one of these conditions isn’t present, the triple combination isn’t met, so the exemption would still be applicable. That’s why the scenario describing all three adverse conditions—low visibility, stronger crosswinds, and poor braking action—is the correct one. The other options don’t capture the necessity of all three factors occurring together, so they don’t describe when the exemption should not apply.
