The table below provides more details about each information item contained in the diagram. It also provides the mapping of each information item within the AIXM 5.1.1 structure. The name of the variable (first column) is recommended for use as label of the data field in human-machine interfaces (HMI).
Data item | Description | AIXM mapping |
|---|---|---|
airport designator | The published designator of the airport where the apron is located, used in combination with other elements in order to identify the apron portion concerned. | AirportHeliport.designator |
airport name | The published name of the airport where the apron is located, used in order to identify the apron(s) and/or apron portion(s) concerned. | AirportHeliport.name |
apron name | The published name of the apron concerned. This information is used in combination with the airport designator/name in order to identify the affected apron(s) and/or apron portion(s) | Apron.name |
| apron portion closed limitation geometry | The coordinates defining the apron portion affected by the limitation. | ApronElement.extent/ElevatedSurface.posList |
location and extent description | Textual description of the limitation-affected apron portion location and extent. | ApronElement.annotation with propertyName="extent" and purpose="DESCRIPTION" |
| conditional for | The description of one or more operations, which is permitted under special conditions, usually a prior permission requirement | ApronElement.availability.ApronAreaAvailability.operationalStatus with value 'LIMITED' and ApronElement/..Availability/..Usage.type with value 'CONDITIONAL' |
| closed, except for | Apron portion is closed, except for operations explicitly identified in the input data. | ApronElement.availability.ApronAreaAvailability.operationalStatus with value 'LIMITED' and ApronElement/..Availability/..Usage.type with value 'RESERV' |
| prohibited for | The description of one or more operations that are prohibited for during the event duration. | ApronElement.availability.ApronAreaAvailability.operationalStatus with value 'LIMITED' and ApronElement/..Availability/..Usage.type with value 'FORBID' |
additionally allowed for | The description of one or more additional operations that are available for a specific purpose during the event duration. | ApronElement.availability.ApronAreaAvailability.operationalStatus with value 'OTHER:EXTENDED' and ApronElement/..Availability/..Usage.type with value 'PERMIT' |
| operation | The specific type of operation concerned by the usage limitation update. | ApronElement/..Availability/..Usage.operation with the following list of values CodeOperationManoeuvringAreaType |
aircraft | The description of one or more aircraft (such as "helicopter") types that are exceptionally permitted on the apron portion during it's limitation. | ApronElement/ApronAreaAvailability/..Usage/../AircraftCharacteristics. Note that only certain properties can be used in this scenario. See data coding rules for details. |
flight | The description of one or more type of flight categories (such as "emergency") that are exceptionally permitted on the apron portion during its limitation. | ApronElement/ApronAreaAvailability/..Usage/../FlightCharacteristics |
| PPR time | The value (minutes, hours, days) of the prior permission request associated with a permitted operation. | ApronElement/ApronAreaAvailability/..Usage.priorPermission with uom attribute |
| PPR details | Additional information concerning the prior permission requirement. | ApronElement/ApronAreaAvailability/..Usage.annotation with propertyName="priorPermission" and purpose="REMARK" |
reason | The reason for the apron portion usage limitation. | ApronElement/ApronAreaAvailability.annotation with propertyName="operationalStatus" and purpose="REMARK". Note that the property "warning" of the ApronAreaAvailability class is not used here because it represents a reason for caution when allowed to operate on the apron, not a reason for a limitation. |
start time | The effective date & time when the apron portion limitation starts. This might be further detailed in a "schedule". | ApronElement/ApronTimeSlice/TimePeriod.beginPosition, Event/EventTimeSlice.validTime/beginPosition and Event/EventTimeSlice.featureLifetime/beginPosition |
end time | The end date & time when the apron portion limitation ends. | ApronElement/ApronTimeSlice/TimePeriod.endPosition, Event/EventTimeSlice.validTime/endPosition and Event/EventTimeSlice.featureLifetime/endPosition also applying the rules for {{Events with estimated end time}} |
schedule | A schedule might be provided, in case the apron portion's usage is effectively limited according to a regular timetable, within the overall limitation period. | ApronElement/ApronAreaAvailability/Timesheet/...according to the rules for {{Schedules}} |
note | A free text note that provides further details concerning the apron portion limitation. | ApronElement/ApronAreaAvailability.annotation with purpose=”REMARK” |
