During 0600Z to 0800Z what visibility is forecast for KOKC?

• A. Less than 1 statute mile
• B. 3 statute miles
• C. Greater than 6 statute miles
• D. 5 to 6 statute miles

Answer: (C)

In aviation weather forecasting, visibility is given in statute miles, and when the forecast calls for visibility greater than 6 miles, it is written as P6SM. For KOKC during 0600Z to 0800Z, the forecast indicates P6SM, meaning visibility is greater than 6 statute miles. This reflects very good visibility, suitable for all typical flight activities. The other options would correspond to lower visibility readings (for example, 3SM, 5–6SM, or less than 1SM) and would be shown with those specific values rather than the P6SM shorthand. The Z times indicate UTC, and this window is just the forecast period in the TAF for that airport.
