What is the basic width of a VHF airway based on 2 VORs?

The basic width of a VHF airway, which is designed for navigation between two VOR (VHF Omnidirectional Range) stations, is defined as 4 nautical miles. This width provides adequate lateral clearance for aircraft navigating the airway, ensuring safe operation despite small deviations from the intended course.

The VHF airway structure implements a central line, which is designated as the airway itself, with the 4 nautical mile width extending 2 nautical miles on either side of this centerline. This standard helps ensure that aircraft will remain within the confines of the designated airway during flight.

Understanding this dimension is crucial for pilots and air traffic controllers to maintain safe separation between aircraft, manage airspace efficiently, and avoid potential navigational conflicts. Knowledge of airway dimensions and specifications is essential in flight planning and navigation, supporting safe operations within controlled airspace.
