Definition

...

  • 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 taxiway 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:

  1. The application shall allow graphical display and selection of taxiway(s) and/or taxiway portion(s) to be closed;

  2. The HMI application should support the operator in identifying all relevant taxiways, taxiways portions and other elements that are affected by the closure and have an impact on operations. As a general rule, if an intersection has to be closed, the Taxiways and/or TaxiwayElements linked to this intersection shall also be closed up to the intersection.

  3. The application shall support the operator in avoiding cul-de-sac/dead-end situations and warn on situations when other Taxiways and/or TaxiwayElements are leading to nowhere. The application shall suggest to either include them in the NOTAM or generate a new NOTAM, as appropriate. 
  4. The operator shall be the one manually selecting all the portions to be closed. 

TaxiwayElement(s) identified as explained in the Data Encoding Rule ER-01. 

status=CLOSEDThe 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, 
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 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
