The temporary closure of a portion of an area intended to accommodate aircraft for purposes of loading or unloading passengers, mail or cargo, fuelling, parking or maintenance. The closure can be total (any traffic is forbidden) or partial (with the exception of particular operations, flights or aircraft categories).
Notes:
- this scenario includes the closure of a portion of an apron. It is assumed that the apron portion does not exist in the baseline data, and has to be created for the event;
- this scenario does not cover the temporary addition of a supplementary restriction to the apron availability, such as "closed for aircraft heavier than...".
- this scenario does not cover the temporary change of the operational hours of an apron element;
- this scenario does not cover the situation when the apron element is operating normally, but subject to a reason for caution (such as "grass cutting in progress", etc.).

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 relative location | A textual description of the area to be closed | ApronElement.annotation with propertyName="extent" and purpose="REMARKDESCRIPTION" |
| apron portion closed geometry | The coordinates defining the apron portion to be closed. | ApronElement.extent/ElevatedSurface |
| closed length | The length of the apron portion to be closed | ApronElement.length |
| closed width | The width of the apron portion to be closed | ApronElement.width |
closure reason | The reason for the apron portion closure. | 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 closure. |
start time | The effective date & time when the apron closure starts. This might be further detailed in a "schedule". | ApronElement/ApronTimeSlice/TimePeriod.beginPosition, Event/EventTimeSlice.validTime/timePosition and Event/EventTimeSlice.featureLifetime/beginPosition |
end time | The end date & time when the apron closure ends. | ApronElement/ApronTimeSlice/TimePeriod.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 is effectively closed according to a regular timetable, within the overall closure period. | ApronElement/ApronAreaAvailability/Timesheet/...according to the rules for {{Schedules}} |
note | A free text note that provides further details concerning the apron closure. | ApronElement/ManoeuvringAreaAvailability.annotation according to the rules for encoding annotations |

Identifier | Data encoding rule |
|---|---|
ER-01 | The temporary closure of an apron portion shall be encoded as:
|
| ER-02 | ApronElement BASELINE TimeSlice shall shall have ApronAreaAvailability with operationalStatus=CLOSED. |
| ER-03 | ApronElement BASELINE TimeSlice shall have associatedApron xlink:href the Apron on which is located (as selected by the operator) |
| ER-04 | Apron TEMPDELTA shall have RunwayDirection.availability/ManoeuvringAreaAvailability.operationalStatus=LIMITED |
| ER-05 | If the closure is limited to a discrete schedule within the overall time period between the "start time" and the "end time", then this shall be encoded using as many as necessary timeInterval/Timesheet properties for the ApronAreaAvailability of all affected Apron and ApronElement TEMPDELTA Timeslice(s). See the rules for Event Schedules. (e.g. If a ApronElement is closed based on a schedule, its associatedApron TEMPDELTA shall have the same associated schedule  ) |
