NavaidComponent of an ILS system. The DME may be collocated with the Localizer
and the DME may provide the navigable location for the Navaid service.
Properties
collocationGroup NoSequenceType Set of navaid equipments
that are collocated. All
Navaid equipment that has
the same value for this
NavaidComponent ^
property are collocated
together. For example in a
VOR/DME Navaid the VOR
and DME navaid
equipment will be assigned
the same collocationGroup
number = 1. For example
an ILS might have a
Localizer with collocation
Group number = 1 and
collocated DME and
Glidepath sharing
collocationGroup number =
2.
markerPosition CodePositionInILSType A code indicating the
position, in a navaid
landing system, of the
markers situated on the
centreline of a runway. For
example: outer, middle,
etc..
providesNavigableLocation CodeYesNoType Indicates the navaid
equipment used to specify
the navigable location of
the Navaid when the
navaid is used as
significant point

Definition
NavaidEquipment ^
A physical navaid equipment like VOR, DME, localizer, TACAN, etc..
Properties
designator CodeNavaidDesignatorType The identifying code
given to the navaid.
name TextNameType The long name given
to the navaid
equipment.
emissionClass CodeRadioEmissionType A code indicating the
type of emission, as
defined at the 1979
ITU World
Administrative Radio
Conference.
mobile CodeYesNoType Indicates if the navaid
equipment is mobile.
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 eastmagnetic
least,
variation westmagnetic
best"".
magneticVariationAccuracy ValAngleType The accuracy of the
measured angle
between Magnetic
North and True North
at the VOR and at the

dateMagneticVariation DateYearType The year the magnetic
variation was
measured.
flightChecked CodeYesNoType Indicates if the navaid
equipment has been
flight checked.
