What is the minimum visibility requirement for VFR flight?

The minimum visibility requirement for Visual Flight Rules (VFR) flight is generally set at 5 kilometers or more in controlled airspace and for specific categories of airports. This standard ensures that pilots can maintain a clear visual reference to the ground and other aircraft, which is essential for safe navigation and operation under VFR conditions.

Visibility of 5 kilometers allows pilots to see adequately and assess their surroundings, ensuring they can make informed decisions while flying. This requirement is important for maintaining situational awareness, avoiding obstacles, and ensuring the safety of both the pilot and other airspace users.

In some jurisdictions, there might be variations or additional specifications for visibility based on different airspace classifications or flight situations, but 5 kilometers is a common standard for many flight operations. Other options suggest lower visibility requirements, which may not provide the necessary margin for safe flight under VFR conditions.
