Under visual flight rules (VFR), what is the minimum visibility required to operate an aircraft?

Under visual flight rules (VFR), the minimum visibility required to operate an aircraft is typically 3 statute miles during the day. This standard is part of the VFR regulations established by aviation authorities, ensuring that pilots can maintain visual reference to the ground and other aircraft. The 3 statute miles visibility helps pilots to safely navigate, avoid obstacles, and maintain separation from other air traffic.

This requirement also applies to different airspace classifications but can vary slightly depending on specific conditions, such as whether the flight is conducted in controlled or uncontrolled airspace. However, the foundational minimum visibility for VFR operations across most scenarios is set at 3 statute miles, thus ensuring overall safety and effective visual navigation.
