These are ground-based radio navigational aids scattered around the country. Lines between them, called Victor airways, are the primary instrument flight paths throughout the country.

VOR (VHF Omnidirectional Range) Ground- based radio navigation aid. More than 1,000 VORs electronically define Victor Airways and Jet Airways, "highways in the sky." Most IFR and many VFR flights follow airway routes.
