What is the minimum flight visibility required for VFR operations by a helicopter outside controlled airspace?

In New Zealand, the minimum flight visibility required for VFR (Visual Flight Rules) operations by a helicopter outside controlled airspace is indeed 1500 metres. This requirement is established to ensure that pilots can clearly see and avoid other aircraft, geographical features, and any obstacles in their flight path, which is crucial for maintaining safety during VFR flights.

There are specific visibility requirements set by aviation regulations, and for helicopters operating outside controlled airspace, the 1500 metres visibility allows them to navigate effectively while still maintaining a safe margin for visual reference. Greater visibility requirements, such as those mentioned in the other options, apply to different types of flights or conditions, such as flying in controlled airspace or at higher altitudes, making the 1500 metres the appropriate standard for this particular scenario.
