public interface ILcdILS
extends ILcdDataObject, ILcdBounded

This interface describes the geometry and the relationships of an Instrument Landing System (ILS). An ILS is a navigation aid to approach a runway in IFR conditions. An ILS consists of:

• a glide path
• a localizer
• some markers
• a dme

An ILS is considered to be an ILcdBounded object.

Attributes and relationships in AIS domain objects can be required or optional. When unspecified, an attribute or relationship is optional. Note that most optional attributes are modeled using features.

In future releases of AIS, optional attributes or relationship may be added to this interface. When this would happen, existing implementations may just return a specified default value for these new attributes or relationships (for instance 'null'). This will require a minimal effort to update existing code to a new version of AIS.

getBounds

Method Detail

getGlidePath

ILcdGlidePath getGlidePath()

Returns the glide path of this ILS.

A glide path (or glide slope) is a transmitter that provides vertical guidance to aircraft approaching a runway.

Returns:

an instance of an implementation of the ILcdGlidePath interface or null if no glide path was specified

getLocalizer

ILcdLocalizer getLocalizer()

Returns the localizer of this ILS.

A localizer is a transmitter that provides lateral guidance to aircraft approaching a runway.

Returns:

an instance of an implementation of the ILcdLocalizer interface or null if no localizer was specified

getMarker

ILcdMarker getMarker(int aIndex)

Returns the marker at the given index.

A marker beacon is located at known distances along the final approach course of the ILS to provide position information. Marker beacons transmit a cone-shaped signal on a frequency of 75MHz uniquely coded to identify each type of beacon.

Parameters:

aIndex - the index of the marker to be retrieved

Returns:

an instance of an implementation of the ILcdMarker interface or null if no marker was specified for the given index

getMarkerCount

int getMarkerCount()

Returns the number of marker beacons associated with this ILS installation.

Returns:

the number of markers specified for this ILS

getDME

ILcdDME getDME()

Returns the Distance Measuring Equipment (DME) associated with this ILS.

Returns:

an instance of an implementation of the ILcdDME interface or null if no DME was specified
