Data encoding rules

The data encoding rules provided in this section shall be followed in order to ensure the harmonisation of the digital encodings provided by different sources. The compliance with some of these encoding rules can be checked with automatic data validation rules. When this is the case, the number of the encoding rule is mentioned in the data validation rule.

Identifier

Data encoding rule

ER-01

The temporary runway portion closure shall be encoded as:

  • a new Event with a BASELINE TimeSlice (encoding=DIGITAL, scenario=RWE.CLS, version=2.0), for which a PERMDELTA TimeSlice may also be provided; and

  • a TimeSlice of type BASELINE for the ad-hoc RunwayElement feature, for which the “event:theEvent”property points to the Event instance created above;

  • a TimeSlice of type TEMPDELTA for the affected RunwayDirection feature, for which the "event:theEvent" property points to the Event instance created above. 

ER-02

Only the following values shall be used for RunwayElement.type:

  • OTHER:FIRST

  • OTHER:LAST

ER-03

RunwayElement BASELINE TimeSlice shall have associatedRunway xlink:href same as the RunwayDirection element used to define the runway affected by the portion closure.

ER-04

RunwayElement BASELINE TimeSlice shall have RunwayElement.availability/ManoeuvringAreaAvailability.operationalStatus=CLOSED

ER-05RunwayDirection TEMPDELTA shall have RunwayDirection.availability/ManoeuvringAreaAvailability.operationalStatus=LIMITED
ER-06

RunwayDirection TEMPDELTA shall have an annotation with purpose=OTHER:LIMITATION_REASON and DESCRIPTION and note: 

Code Block
titleEBNF Code
collapsetrue
note = "RunwayElement.type" "RunwayElement.length" "RunwayElement.length.uom" "closed".

e.g. "First 300m closed"

Note: This annotation will not be used for the decoding. It is intended only as a note explaining the reason for the "LIMITED" status.

ER-07

If runway portion 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 ManoeuvringAreaAvailability of the RunwayElement BASELINE Timeslice. See the encoding rules for {{Schedules}}.

ER-08

If the temporary baseline RunwayElement has type=OTHER:FIRST then a consequence RCP.CHG scenario shall be encoded for the relevant RunwayCentrelinePoints(s) which shall include a reference to the current event with role “causeEvent”.

ER-09

If the temporary baseline RunwayElement has type=OTHER:LAST then a consequence RDD.CHG scenario shall be encoded for the relevant RunwayDirection which include a reference to the current event with role “causeEvent”
