What is the minimum flight visibility required for a helicopter to transit a Control Zone under day Special VFR?

The minimum flight visibility required for a helicopter to transit a Control Zone under Day Special VFR is indeed 1/2 mile. This regulation allows for flexibility in operation under special visual flight rules, particularly in controlled airspace, and acknowledges the unique operational characteristics and capabilities of helicopters.

In this context, the regulation aims to ensure that pilots maintain sufficient visual reference to the ground and other aircraft while still allowing for operations in areas where standard VFR may not be achievable due to visibility issues. Day Special VFR for helicopters requires this minimum visibility of 1/2 mile, making it distinct from the higher visibility requirements that apply to other types of aircraft under similar conditions.

Understanding this distinction is essential for pilots operating in controlled airspace, as they must be aware of the specific regulations that apply to their aircraft type under various flight rules.
