Assumptions for baseline data

It is assumed that the related ApronElement, Apron and AirportHeliport and BASELINE Timeslice covering the entire duration of the event exist. In addition the information about the aircraft stand(s) concerned by the event already exist in the form of a AircraftStand BASELINE TimeSlice, which contains as a minimum:

  1. designator, and

  2. an association with the ApronElement, which is associated with an Apron, which is associated with an AirportHeliport;

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 closure of an aircraft stand shall be encoded as:

  • a new Event with a 'BASELINE' TimeSlice (scenario='STAND.CLS', version='2.0'), for which a PERMDELTA TimeSlice may also be provided; and
  • a TimeSlice of type 'TEMPDELTA' for each affected AircraftStand feature, for which the "event:theEvent" property points to the Event instance created above;

ER-02

First, all the BASELINE availability.ApronAreaAvailability (with operationalStatus='NORMAL'), if present, shall be copied in the TEMPDELTA. TEMPDELTA (see Usage limitation and closure scenarios)

Then, an additional availability.ApronAreaAvailability element having operationalStatus='CLOSED' shall be coded in the AircraftStand TEMPDELTA.

Editorial note: there is no mistyping - ApronAreaAvailability is the actual name of the object containing information about the operational status of an AircraftStand. 

ER-03

If the aircraft stand 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 (with operationalStatus='CLOSED') of the TEMPDELTA Timeslice. See the rules for Event Schedules.

ER-04

The system shall automatically identify the 'FIR' where the AirportHeliport is located. This shall be coded as corresponding concernedAirspace property in the Event

ER-05The AirportHeliport concerned by the closure shall also be coded as concernedAirportHeliport property in the Event.
