What is the visibility requirement during uncontrolled night flights?

For uncontrolled night flights in New Zealand, the visibility requirement is indeed set at 16 kilometers. This standard is in place to ensure that pilots have sufficient visual reference to navigate safely and effectively during nighttime operations.

The requirement for extended visibility helps to mitigate risks associated with limited visibility conditions, which can arise at night due to lower light levels and the potential for visual illusions. Having a visibility threshold of 16 kilometers promotes safer flying by allowing pilots to maintain awareness of other aircraft, terrain, and obstacles that may not be as easily discernible in the dark. This standard reflects the importance of maintaining situational awareness and enhances operational safety during nighttime flight operations.

In contrast, the other options outline lower visibility requirements that do not align with the regulations for night flights, which emphasize the need for heightened vigilance and clear sightlines.
