How wide are LF/MF airways with an NDB on each end?

The width of LF/MF (Low Frequency/Medium Frequency) airways, when defined by non-directional beacons (NDBs) on each end, is established to ensure safe navigation and the provision of adequate airspace for aircraft operations. In this context, LF/MF airways are designed with a standard width of 4.34 nautical miles. This width is intended to provide sufficient room for aircraft to navigate safely between the NDBs while accounting for lateral deviances that might occur due to navigation inaccuracies or changes in flight paths.

The choice of 4.34 nautical miles is consistent with aeronautical regulations and standard procedures used by air traffic authorities to define airway dimensions. This ensures both safety in navigation and the efficient management of air traffic in controlled airspace. Knowing this standard measurement helps pilots and air traffic controllers maintain situational awareness and ensures safe separation between aircraft operating within those defined airspaces.
