---|---|---|---|---|
class | CodeMarkerBeaconSignalType | A code indicating the class of the radio marker. For example, fan marker, low-powered fan marker, Z marker. | ||
frequency | ValFrequencyType | The value of the radio emission frequency. | ||
axisBearing | ValBearingType | The true bearing of the minor axis of the marker beacon. (source: ARINC 424 Specification) | ||
auralMorseCode | CodeAuralMorseType | The Morse code transmitted by the beacon. | ||
designator | CodeNavaidDesignatorType | The identifying code given to the navaid. | Inherited from NavaidEquipment | |
name | TextNameType | The long name given to the navaid equipment. | Inherited from NavaidEquipment | |
emissionClass | CodeRadioEmissionType | A code indicating the type of emission, as defined at the 1979 ITU World Administrative Radio Conference. | Inherited from NavaidEquipment | |
mobile | CodeYesNoType | Indicates if the navaid equipment is mobile. | Inherited from NavaidEquipment | |
magneticVariation | ValMagneticVariationType | The measured angle between Magnetic North and True North at the VOR and at the time reported in dateMagneticVariation. By convention, the measure is expressed as a positive number if Magnetic North is to the east of True North and negative if Magnetic North is to the west of True North. Therefore, magnetic bearing + magnetic variation = true bearing. The following rule of thumb applies: ""variation east-magnetic least, variation west-magnetic best"". | Inherited from NavaidEquipment | |
magneticVariationAccuracy | ValAngleType | The accuracy of the measured angle between Magnetic North and True North at the VOR and at the time reported in dateMagneticVariation | Inherited from NavaidEquipment | |
dateMagneticVariation | DateYearType | The year the magnetic variation was measured. | Inherited from NavaidEquipment | |
flightChecked | CodeYesNoType | Indicates if the navaid equipment has been flight checked. | Inherited from NavaidEquipment |
