AIP context
The figure below shows how aeronautical ground lights may be published in AD 2.15.
The figure below shows how aeronautical ground lights may be published in AD 3.15.
The figure below shows how aeronautical ground lights may be published in ENR 4.5.
The diagram below shows the AIXM classes, including the relevant data types and code lists, needed to encode that information:
AIXM 5.2 Improvements
A change proposal (AIXM-556) for the next AIXM 5.2 version has been approved by the AIXM Change Control Board, in which new <<object>> LightGroup associated with GroundLightSystem and LightElement was added.
The coding guidelines provided here are aligned with forward/backward conversion rules contained in the AIXM-556 Change Proposal.
Designator / Name
PANS-AIM requires to uniquely identify a beacon either by an identifier or the name of the city or town where it is located.
In AIXM 5, only AeronauticalGroundLight.name is available. This attribute can be used to carry either the identification or the name as defined by PANS-AIM.
In addition, an aerodrome beacon may be identified by its relationship to the AirportHeliport, which it is marking.
AIXM 5.2 Improvement
A change proposal (AIXM-513) for the next AIXM 5.2 version has been approved by the AIXM Change Control Board, which adds the designator to the AeronauticalGroundLight.
The coding guidelines provided here are aligned with forward/backward conversion rules contained in the AIXM-513 Change Proposal.
Type
The AeronauticalGroundLight.type attribute allows to code the following values:
| Value | Description |
|---|---|
| 'BCN' | Beacon |
| 'IBN' | Identification Beacon |
| 'HEL_BCN' | Heliport Beacon |
| 'ABN' | Airport Beacon |
| 'MAR_BCN' | Marine Beacon |
| 'RSP_BCN' | Responder Beacon |
| 'TWR_BCN' | Control tower signalling beacon |
| 'HAZ_BCN' | An aeronautical beacon used to designate a danger to air navigation. |
| 'OTHER' | OTHER |
Intensity
AIXM 5 does not provide a dedicated attribute for the intensity of the aeronautical ground light.
A Note has to be used to provide that information (for details on how to encode notes, see the topic Note [NTE]).
AIXM 5.2 Improvement
Characteristics of Signal
AIXM 5 does not provide a dedicated attribute for the characteristics of the aeronautical ground light. It does provide the possibility to code some characteristics, though by using
- AeronauticalGroundLight.colour to code the primary colour of the light source, and
- AeronauticalGroundLight.flashing to give an indication whether the light is steady or flashing.
Any other characteristics have to be coded as Note (for details of how to encode notes, see the topic Note [NTE]).
Operational Hours
AIXM 5 does not provide the possibility to code the operational hours of an aeronautical ground light.
Currently, this can only be done by using a Note (for details on how to encode notes, see the topic Note [NTE]).
Position
The position for the aeronautical ground light is not required for ENR 4.5 and in general also not published in an AIP. Hence, it is not considered being part of the minimum/conditional data for the AIP data set. However, in AIXM, the position may be encoded by the AeronauticalGroundLight.location property using the Point class.
For more details about the encoding of points including coding rules refer to the topic Geometry.
Coding Examples
Coding examples can be found in the AIP Data Set - Specimen (DONLON).
