What is the required visibility for Class G airspace at or above 10,000 feet MSL (and above 1,200 feet AGL)?

In Class G airspace, the visibility requirements vary depending on the altitude and conditions. For airspace at or above 10,000 feet MSL and above 1,200 feet AGL, the FAA specifies a visibility requirement of 5 statute miles. This requirement is in place because as altitude increases, the ability to see and avoid other aircraft is crucial due to the volume of air traffic at higher altitudes and the significant distance visibility must encompass to properly avoid collisions.

This visibility threshold is designed to ensure that pilots have adequate sight lines to maintain visual separation from other aircraft and navigate safely. The specific regulation helps create a safer flying environment by addressing the potential challenges of flying at higher altitudes where weather and other variables can contribute to decreased visibility.
