What is the visibility requirement in miles for operations on a VR route?

The visibility requirement for operations on a VR (Visual Routes) route is established to ensure that pilots have sufficient visual reference to navigate safely. A visibility of 5 miles allows pilots to adequately observe and respond to air traffic, terrain, and other obstacles while on the route. This requirement supports maintaining a safe distance from other air traffic and facilitates effective situational awareness. While options suggesting lesser visibility distances could theoretically allow flying, they do not meet the safety standards necessary for operations on visual routes, where visual navigation is paramount. Thus, the requirement of 5 miles strikes an appropriate balance between operational flexibility and safety.
