Under positive control, which is the minimum visibility required for helicopters?

Under positive control, air traffic control provides separation and sequencing for aircraft, so helicopters can operate in somewhat poorer visibility than would be allowed without ATC guidance. The minimum visibility to operate in this environment is 1 mile, meaning you need at least this visibility to fly VFR under ATC supervision. In contrast, standard VFR minimums in many controlled airspaces call for higher visibility (typically around 3 miles) unless you’re operating under a Special VFR clearance, which still centers on staying clear of clouds and meeting the ATC authorization. So the idea is that ATC’s presence allows the helicopter to operate with effectively lower minimum visibility, with 1 mile serving as that threshold.
