What is the minimum flight visibility in Class B airspace at or above 10,000 feet AMSL?

In Class B airspace at or above 10,000 feet AMSL, the minimum flight visibility requirement is 8 kilometers. This standard is established to ensure that pilots can maintain visual separation from other aircraft and navigate safely within this controlled airspace. At higher altitudes, the increased visibility requirement reflects the greater distances over which pilots must be able to see and identify other traffic, as well as avoid terrain or obstacles.

The 8 km visibility standard balances the need for safety and effective communication among pilots operating in this busy airspace, where multiple aircraft may be converging. Additionally, it aligns with the need for pilots to have a wider visual range to manage their flight path accurately in conjunction with air traffic control.

The choice that states 10 km is notably a more stringent requirement than necessary for this specific airspace classification at the indicated altitude, whereas the options of 5 km and 16 km do not align with the regulations for visibility in this context either, making 8 km the correct and appropriate minimum visibility requirement.
