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.LIM, 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.

Then, an additional availability.ApronAreaAvailability element shall be included in the Apron TEMPDELTA having:

  • operationalStatus=LIMITED if the apron usage is "conditional for", "closed, except for", "prohibited for";
  • operationalStatus=OTHER:EXTENDED if the apron usage is "allowed for".

Note: 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 usage is "conditional for" specified operations, flight and/or aircraft categories, then all specified limitations shall be encoded as ApronAreaUsage child elements with type=CONDITIONAL.

ER-04

If the aircraft stand is "closed, except for" specified operations, flight and/or aircraft categories, then all specified limitations shall be encoded as ApronAreaUsage child elements with type=RESERV.

ER-05

If the aircraft stand usage is "prohibited for" specified operations, flight and/or aircraft categories, all specified limitations shall be encoded as ApronAreaUsage child elements with type=FORBID.

ER-06If the aircraft stand usage is "allowed for" specified operations, flight and/or aircraft categories, all specified limitations shall be encoded as ApronAreaUsage child elements with type=PERMIT.
ER-07

If a unique flight or aircraft is specified as part of the condition, they shall be encoded as one ConditionCombination with logicalOperator="NONE".

Otherwise, each pair of flight and aircraft shall be encoded as one ConditionCombination with logicalOperator="AND".

ER-08

If PPR time is specified, the uom attribute shall also be specified.

ER-09

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

ER-10The AirportHeliport concerned by the closure shall also be coded as concernedAirportHeliport property in the Event.
