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 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' |
aircraft | The description of one or more aircraft (such as "helicopter") types that are exceptionally permitted on the apron portion during it's limitation. | AirportHeliportApronElement/..Availability/..Usage/..selection/..AircraftCharacteristics Only the following AircraftCharacteristics properties are allowed to be used in this scenario: type, engine, wingSpan, wingSpanInterpretation, weight, weightInterpretation. |
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. | AirportHeliportApronElement/..Availability/..Usage/..selection/..FlightCharacteristics. Only the following FlightCharacteristics properties are allowed to be used in this scenario: type, rule, status, military, origin, purpose. |
| PPR time | The value (minutes, hours, days) of the prior permission request associated with a permitted operation. | ApronElement/ApronAreaAvailability/..Usage.priorPermission with uom attribute specified |
| 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 forEvents 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' |
