Each NavaidEquipment will have a location defined by the Point class. For certain NavaidEquipment an elevation has to be defined. In this case, the ElevatedPoint class has to be used (e.g. for DME).
...
The NavaidEquipment may also have a designator and a name, which in general will be the same as the one of the Navaid.
In addition, each NavaidEquipment may have a magneticVariation defined. Only VOR and TACAN have also a declination, i.e. the angular difference between True North and the station declination (Magnetic North - as indicated by the station).
Some NavaidEquipment have a frequency (e.g. VOR or NDB), whereas others have a channel defined (e.g. TACAN TACAN or DME).
Some NavaidEquipment have a defined magneticBearing and/or trueBearing (e.g. the measured angle between the localizer beam and Magnetic/True North at the localizer antenna).
