Definition

The temporary closure of a portion of a runway towards one of its ends (for example: work in progress at one runway end). 

Notes:

  • this scenario covers the closure of a runway portion at the beginning or the end of the runway;
  • this scenario does not cover the eventual change of the runway centerline points as a consequence for portion closure. For this situation refer to THR.CHG scenario;
  • this scenario does not cover the eventual change of the runway centerline points as a consequence for portion closure. For this situation refer to RDD.CHG scenario;
  • this scenario does not cover the closure of a runway portion except for operations;
  • this scenario does not cover the change of the RWY width;
  • this scenario does not cover the unavailability of a turning bay at the end of the runway. For this situation refer to APN.CLS scenario (work in progress);

this scenario covers only closures which include either the start or the end of a runway (no middle sections)

Event data

The following diagram identifies the information items that are usually provided by a data originator for this kind of event.

EBNF Code 
input = "airport designator" ["airport name"] "runway direction" ["runway surface composition"] \n
"runway section closed" "closed length" \n
"start time" "end time" ["schedule"] {note}.

The table below provides more details about each information item contained in the diagram. It also provided the mapping of each information item within the AIXM 5.1 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 runway is located, used in combination with other elements in order to identify the runway concerned.

AirportHeliport.designator

airport name

The published name of the airport where the runway is located, used in order to identify the runway concerned.

AirportHeliport.name

runway direction

The published designator of the runway direction concerned. This information is used in combination with the airport designator/name in order to identify the runway affected by the portion closure.

RunwayDirection.designator


runway section closed

The indication of the portion of the runway to be closed. The available options should be only “first” or “last” having as reference the runway direction for which the event is concerned.

RunwayElement.type

closed length

The length of the runway  element portion to be closed.

RunwayElement.length

start time

The effective date & time when the runway portion closure starts. This might be further detailed in a "schedule".

RunwayElement/ RunwayElementTimeSlice.validTime/TimePeriod.beginPosition,

Event/EventTimeSlice.validTime/ TimePeriod.beginPosition,

RunwayElement/ RunwayElementTimeSlice.featureLifetime/beginPosition,

and Event/EventTimeSlice.featureLifetime/beginPosition

end time

The end date & time when the runway portion closure ends.

RunwayElement/ RunwayElementTimeSlice.validTime/TimePeriod.endPosition,

Event/EventTimeSlice.validTime/ TimePeriod.endPosition,

RunwayElement/ RunwayElementTimeSlice.featureLifetime/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 runway portion is effectively closed according to a regular timetable, within the overall closure period.
