For a circle-to-land dispatch, the forecast weather conditions at the ETA must indicate that

• A. The visibility will be at or above 3 SM at the ETA
• B. The ceiling will be at or above 1000' at the ETA
• C. Both of these must be true
• D. Neither of these conditions is required

Answer: (C)

Circle-to-land operations rely on having enough weather to complete the maneuver visually after the instrument approach. The forecast at the estimated time of arrival must show both a visibility of at least 3 statute miles and a ceiling of at least 1000 feet. The 3 SM visibility provides sufficient horizontal sight distance to maintain visual references to the runway and surrounding terrain during the circling maneuver, while the 1000-foot ceiling ensures there is adequate vertical clearance and room to maneuver from the approach environment to the landing runway without encountering obstacles or airspace constraints. Because the ability to safely execute a circle-to-land depends on meeting both visual and cloud-clearance requirements, the forecast must indicate that neither condition is below the minimums. Hence, both conditions must be true.
