Definition
The temporary closure of movement areas established for the taxiing of aircraft or parts thereof.The closure can be total (any traffic is forbidden) or partial (with the exception of particular flights or aircraft categories).
Notes:
- this scenario includes the closure of one or more full taxiways (could be all the taxiways at the airport);
- this scenario includes closure of taxiway portions, provided the taxiway elements exist in the baseline data (see the specific assumptions for baseline data);
- this scenario requires a graphical view of the taxiways and taxiways portions;
- this scenario does not cover the "partial" closure, nor the temporary addition of a supplementary restriction to the apron availability, such as "closed for aircraft heavier than...". This is referenced in TWY.LIM scenario;
- more than one taxiway can be included only if the closure conditions applies equally to all taxiways. Otherwise, separate NOTAM shall be issued;
- this scenario does not cover the temporary change of the operational hours of a taxiway;
- this scenario does not cover the situation when the taxiway 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 taxiway is located, used in combination with other elements in order to identify the taxiway(s) and/or taxiway portion(s) concerned. | AirportHeliport.designator |
airport name | The published name of the airport where the taxiway is located, used in order to identify the taxiway(s) and/or taxiway portion(s) concerned. | AirportHeliport.name |
taxiway designator | The published designator of the taxiway concerned. This information is used in combination with the airport designator/name in order to identify the affected taxiway(s) and/or taxiway portion(s) | Taxiway.designator |
closed taxiway portion input | The portion of a published taxiway, specified using intersection elements between that taxiway and other taxiways, runways, aprons or stands. Note on closed taxiway portion input:
| TaxiwayElement(s) identified as explained in the Data Encoding Rule ER-01. |
| status=CLOSED | The operational status of the taxiway. In this scenario, it is only possible to indicate a complete closure. | Taxiway/ or TaxiwayElement/ManoeuvringAreaAvailability.operationalStatus |
closure reason | The reason for the taxiway(s) and/or taxiway portion(s) closure. | Taxiway/ or TaxiwayElement/ManoeuvringAreaAvailability.annotation with propertyName="operationalStatus" and purpose="REMARK". Note that the property "warning" of the ManoeuvringAreaAvailability class is not used here because it represents a reason for caution when allowed to operate on the taxiway, not a reason for a closure. |
start time | The effective date & time when the taxiway closure starts. This might be further detailed in a "schedule". | Taxiway/ or TaxiwayElement/TaxiwayTimeSlice/TimePeriod.beginPosition, Event/EventTimeSlice.validTime/beginPosition and Event/EventTimeSlice.featureLifetime/beginPosition |
end time | The end date & time when the taxiway closure ends. | Taxiway/ or TaxiwayElement/TaxiwayTimeSlice/TimePeriod.endPosition, |
schedule | A schedule might be provided, in case the taxiway is effectively closed according to a regular timetable, within the overall closure period. | Taxiway/ or TaxiwayElement/ManoeuvringAreaAvailability/Timesheet/...according to the rules for {{Schedules}} |
note | A free text note that provides further details concerning the taxiway closure. | Taxiway/ or TaxiwayElement/ManoeuvringAreaAvailability.annotation according to the rules for encoding annotations |
