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

The table below provides more details about each information item contained in the diagram. It also provides 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 aircraft stand is located, used in combination with other elements in order to identify the aircraft stand concerned. | AirportHeliport.designator |
airport name | The published name of the airport where the aircraft stand is located, used in order to identify the aircraft stand concerned. | AirportHeliport.name |
| aircraft stand designator | The designator of the aircraft stand to be closed. | AircraftStand.designator |
| status=CLOSED | The operational status of the aircraft stand. In this scenario, it is only possible to indicate a complete closure. | AircraftStand/ApronAreaAvailability.operationalStatus |
closure reason | The reason for the aircraft stand closure. | AircraftStand/ApronAreaAvailability.annotation with propertyName="'operationalStatus" ' and purpose="'REMARK"'. Note that the property "warning" of the ApronAreaAvailability class is not used here because it represents a reason for caution when allowed to operate at the aircraft stand, not a reason for a closure. |
start time | The effective date & time when the aircraft stand closure starts. This might be further detailed in a "schedule". | AircraftStand/AircraftStandTimeSlice/TimePeriod.beginPosition, Event/EventTimeSlice.validTime/beginPosition and Event/EventTimeSlice.featureLifetime/beginPosition |
end time | The end date & time when the aircraft stand closure ends. | AircraftStand/AircraftStandTimeSlice/TimePeriod.endPosition, Event/EventTimeSlice.validTime/endPosition and Event/EventTimeSlice.featureLifetime/endPosition also applying the rules for Event update and cancellationwith estimated end time |
schedule | A schedule might be provided, in case the aircraft stand is effectively closed according to a regular timetable, within the overall closure period. | AircraftStand/ApronAreaAvailability/Timesheet/...according to the rules for {{Schedules}} |
note | A free text note that provides further details concerning the aircraft stand closure. | AircraftStand/ApronAreaAvailability.annotation according to the rules for encoding annotations with purpose='REMARK' |
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
...
:
- designator, and
...
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:
|
ER-02 | First, all the BASELINE availability.ApronAreaAvailability (with operationalStatus='NORMAL'), if present, shall be copied in the TEMPDELTA. Then, an additional availability.ApronAreaAvailability element having operationalStatus='CLOSED' shall be coded in the AircraftStand TEMPDELTA. Note: No 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 Air TEMPDELTA Timeslice. See the rules for Event Schedules. |
| ER-04 | The system shall automatically identify the 'FIR' where the AerodromeHeliport AirportHeliport is located. This shall be coded as corresponding concernedAirspace property in the Event |
| ER-05 | The AirportHeliport concerned by the closure shall also be coded as concernedAirportHeliport property in the Event. |
