When utilizing positive control, what is the ceiling and visibility required for fixed wing and helos?

Positive control relies on weather minimums that reflect the different capabilities of aircraft. Controllers can maintain separation more readily with fixed‑wing traffic at higher speeds, longer turns, and higher performance, so the minimums are stricter for helicopters and looser for fixed‑wing in this context. The correct choice matches that idea: fixed‑wing operations under positive control require ceilings below 1000 feet and visibility of 5 miles or more, while helicopters can operate with ceilings below 500 feet and visibility down to about 1 mile or less. This reflects the helicopter’s ability to maneuver at lower altitudes and in reduced visibility, whereas fixed‑wing aircraft generally need better conditions to ensure safe separation under positive control. The other options either swap the relative stringency between aircraft types or present equal or inconsistent minimums that don’t align with how helicopter and fixed‑wing performance influence controllability.
