Class - Localizer
<< feature >> Logical View.AIXM.AIXM Features.Navaids Points.Navaids
<<feature>> A component of an ILS consisting of a VHF transmitter, radiating signals in the direction served by the ILS, to provide a straight line descent path in the vertical plane containing the centre line of the runway.
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 | ||
|---|---|---|---|---|
| frequency | ValFrequencyType | The frequency of the localizer. | ||
| magneticBearing | ValBearingType | The measured angle between the localizer beam and Magnetic North at the localizer antenna. | ||
| magneticBearingAccuracy | ValAngleType | Accuracy of the measured angle between the localizer beam and Magnetic North at the localizer antenna. | ||
| trueBearing | ValBearingType | The measured angle between the localizer beam and True North at the localizer antenna. Note : The True North is the north point at which the meridian lines meet. | ||
| trueBearingAccuracy | ValAngleType | Accuracy of the measured angle between the localizer beam and True North at the localizer antenna. | ||
| declination | ValMagneticVariationType | The angular difference between True North and the station declination (Magnetic North - as indicated by the station). | ||
| widthCourse | ValAngleType | The localizer course width, in degrees. | ||
| widthCourseAccuracy | ValAngleType | Accuracy of the localizer course width, in degrees. | ||
| backCourseUsable | CodeILSBackCourseType | A code indicating the usability of the localizer signal in the back course sector. | ||
| 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 |
