12000 feet 60 miles, referred to in aviation as “12000 60”, is the standard altitude and visibility minima for visual flight rules (VFR) in the United States.
VFR is a set of regulations that govern the operation of aircraft during periods of good visibility. In order to fly under VFR, pilots must maintain visual contact with the ground and be able to see other aircraft in the vicinity. The 12000 60 minima ensure that pilots have sufficient visibility to operate their aircraft safely.
The 12000 60 minima are not absolute, and may be adjusted by air traffic control (ATC) based on the prevailing weather conditions. For example, in areas with high terrain, ATC may require pilots to maintain a higher altitude than 12000 feet. Similarly, in areas with poor visibility, ATC may require pilots to maintain a greater visibility than 60 miles.
