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 | CodeDMEType | The particular spectrum characteristics or accuracy of Ultra High Frequency (UHF) Distance Measuring Equipment (DME), as a category. | ||
| channel | CodeDMEChannelType | The channel of the DME. See Annex 10, Table A, end of Chapter 3 for channelling details and for a list of allowable values. | ||
| ghostFrequency | ValFrequencyType | The frequency of a virtual VHF facility paired with the DME according to ICAO Annex 10, table A, ch.3. | ||
| displace | ValDistanceType | The distance from the DME antenna to the position where the zero range indication occurs in the DME receiver. | ||
| 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 |
