Name Type Definition Description
AeroRadioNavInstallation_P Feature Type A ground based piece of electronic equipment that provides aeronautical navigation guidance information or position data. -
DistanceMeasuringEquipment_P Feature Type Ultra High Frequency (UHF) ground equipment that is used in conjunction with airborne equipment to determine distance between the airborne and ground equipment. DME Distance is defined as the line of sight distance (slant range) from the source of a DME signal to the receiving antenna. DME operates on the interrogation-answer principle where the time required for the round trip of the signal exchange is measured in the airborne DME unit and translated into DME Distance.
DistanceMeasuringEquipment_S Feature Type Ultra High Frequency (UHF) ground equipment that is used in conjunction with airborne equipment to determine distance between the airborne and ground equipment. DME Distance is defined as the line of sight distance (slant range) from the source of a DME signal to the receiving antenna. DME operates on the interrogation-answer principle where the time required for the round trip of the signal exchange is measured in the airborne DME unit and translated into DME Distance.
NonDirectionalRadioBeacon_P Feature Type A low or medium radio navigation service transmitting signals whereby the pilot of a suitably equipped aircraft can determine bearings, 'home in' on, and/or track to or from the station. The radio frequencies assigned to an NDB shall be selected from those available in that portion of the spectrum between 190 and 1750 kilohertz (kHz).
TacticalAirNavAidBeacon_P Feature Type A military Ultra High Frequency (UHF) radio navigation service able to provide continuous bearing and Distance Measuring Equipment (DME) distance to a selected station. A navigation system developed by military and naval forces providing, as far as the navigating pilot is concerned and for suitably equipped aircraft, the same indication as a VOR/DME system. DME Distance is defined as the line of sight distance (slant range) from the source of a DME signal to the receiving antenna.
VhfOmniRadioBeacon_P Feature Type A Very High Frequency (VHF) radio navigation service which uses phase comparisons of a ground transmitted signal to determine bearing. This term is derived from the expression 'very high frequency omnidirectional radio range'.
