Legend 17: Airport/Facility Directory

AIRPORT/FACILITY DIRECTORY LEGEND 27 RADIO CLASS DESIGNATIONS VOR/DME/TACAN Standard Service Volume (SSV) Classifications NOTE: Additionally, (H) facilities provide (L) and (T) service volume and (L) facilities provide (T) service. Altitudes are with respect to the station's site elevation. Coverage is not available in a cone of airspace directly above the facility. The term VOR is, operationally, a general term covering the VHF omnidirectional bearing type of facility without regard to the fact that the power, the frequency protected service volume, the equipment configuration, and operational requirements may vary between facilities at different locations. SSV Class Altitudes Distance (NM) (T) Terminal 1000´ to 12,000´ 25 (L) Low Altitude 1000´ to 18,000´ 40 (H) High Altitude 1000´ to 14,500´ 40 14,500´ to 18,000´ 100 18,000´ to 45,000´ 130 45,000´ to 60,000´ 100 AB ___________________ Automatic Weather Broadcast. DF ___________________ Direction Finding Service. DME _________________ UHF standard (TACAN compatible) distance measuring equipment. DME(Y) _______________ UHF standard (TACAN compatible) distance measuring equipment that require TACAN to be placed in the “Y” mode to receive DME. GS ___________________ Glide slope. H ____________________ Non–directional radio beacon (homing), power 50 watts to less than 2,000 watts (50 NM at all altitudes). HH __________________ Non–directional radio beacon (homing), power 2,000 watts or more (75 NM at all altitudes). H–SAB…
