Class - VOR
<< feature >> Logical View.AIXM.AIXM Features.Navaids Points.Navaids
<<feature>> A VHF omnidirectional radio range beacon. A short-range, very-high-frequency omnidirectional beacon which provides an indication in the aircraft of the bearing of the beacon, or left-right track indication.
Inheritance
This is a specialization of the NavaidEquipment class and it inherits all attributes and associations of that class.
List of attributes
| Name | Data Type | Definition | ||
|---|---|---|---|---|
| type | CodeVORType | A code indicating a type of VOR, e.g. conventional VOR or Doppler VOR. | ||
| frequency | ValFrequencyType | The value of the frequency. | ||
| zeroBearingDirection | CodeNorthReferenceType | A code indicating the direction of the 'zero bearing' provided by the station. For example: magnetic north, true north. | ||
| declination | ValMagneticVariationType | The angular difference between True North and the station declination (Magnetic North - as indicated by the station). | ||
| 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 |
