Figure 2-23. Low frequency airway G13.  Figure 2-22. Chart Supplement (NE), Tower En Route Control route descriptions (Atlantic City).  Airway and Route System  Airway/Route Depiction  2-13  IFR en route charts show all IFR radio NAVAIDs that have  been flight-checked by the FAA and are operational. The  FAA, Aeronautical Information Services publishes and  distributes U.S. Government Civil Aeronautical Charts and  flight information publications. IFR en route navigation  information is provided on three charts: IFR en route low  altitude chart, IFR en route high altitude chart, and Terminal  Area Chart (TAC). [Figure 2-24A and B]  There are three fixed route systems established for  air navigation purposes. They are the Federal airway  consisting of VOR (low victor airways, high jet routes),  NDB (low or medium frequency) and the RNAV route  system. To the extent possible, these route systems are  aligned in an overlying manner to facilitate transition  between each. The majority of the airways are made up  of victor airways, jet routes, and RNAV, but some low/  medium frequency (L/MF) airways and routes are still  being used in Alaska and one other that is located off  the coast of North Carolina and is called Green 13 (G13).
