| operation | The specific type of operation concerned by the usage limitation update. | Taxiway/..Usage.operation and TaxiwayElement/..Usage.operation |
aircraft | The description of one or more aircraft (such as "helicopter") types are permitted or prohibited (depending on the limitation type) during the event duration. | Taxiway/ManoeuvringAreaAvailability/Usage/..selection/..AircraftCharacteristics and TaxiwayElement/ManoeuvringAreaAvailability/Usage/..selection/..AircraftCharacteristics Only the following AircraftCharacteristics properties are allowed to be used in this scenario: type, engine, wingSpan, wingSpanInterpretation, weight, weightInterpretation. |
flight | The description of one or more type of flight categories (such as "emergency") that are permitted or prohibited (depending on the limitation type) during the event duration. | Taxiway/ManoeuvringAreaAvailability/Usage/..selection/..FlightCharacteristics and TaxiwayElement/ManoeuvringAreaAvailability/Usage/..selection/..FlightCharacteristics Only the following FlightCharacteristics properties are allowed to be used in this scenario: type, rule, status, military, origin, purpose. |
| PPR time | The value (minutes, hours, days) of the prior permission request associated with a permitted operation. | Taxiway/ManoeuvringAreaAvailability/Usage.priorPermission with uom attribute and TaxiwayElement/ManoeuvringAreaAvailability/Usage.priorPermission with uom attribute |
| PPR details | Additional information concerning the prior permission requirement. | Taxiway/ManoeuvringAreaAvailability/Usage.annotation with propertyName='priorPermission' and purpose='REMARK' TaxiwayElement/ManoeuvringAreaAvailability/Usage.annotation with propertyName='priorPermission' and purpose='REMARK' |
reason | The reason for the taxiway usage limitation. | Taxiway.availability.ManoeuvringAreaAvailability.annotation with propertyName='operationalStatus' and purpose='REMARK'. Note that the property "warning" of the ManoeuvringAreaAvailability class is not used here because it represents a reason for caution when allowed to operate on the taxiway, not a reason for a closure. |
start time | The effective date & time when the taxiway limitation starts. This might be further detailed in a "schedule". | Taxiway/TaxiwayTimeSlice/TimePeriod.beginPosition, TaxiwayElement/TaxiwayElementTimeSlice/TimePeriod.beginPosition, Event/EventTimeSlice.validTime/beginPosition and Event/EventTimeSlice.featureLifetime/beginPosition |
end time | The end date & time when the taxiway limitation ends. | Taxiway/TaxiwayTimeSlice/TimePeriod.endPosition, TaxiwayElement/TaxiwayElementTimeSlice/TimePeriod.endPosition, Event/EventTimeSlice.validTime/endPosition and Event/EventTimeSlice.featureLifetime/endPosition also applying the rules forEvents with estimated end time |
schedule | A schedule might be provided, in case the taxiway's usage is effectively limited according to a regular timetable, within the overall limitation period. | Taxiway.availability.ManoeuvringAreaAvailability/Timesheet/... and TaxiwayElement.availability.ManoeuvringAreaAvailability/Timesheet/...according to the rules for Schedules |
note | A free text note that provides further details concerning the taxiway limitation. | Taxiway.availability.ManoeuvringAreaAvailability.annotation with purpose='REMARK' |

Identifier | Data encoding rule |
|---|---|
ER-01 | The temporary limitation of a taxiway or portion thereof shall be encoded as:
Important Note: the application shall support the operator in order to automatically select the TaxiwayElements that are concerned with a graphical view, as indicated in the figure below. By default, intersections are supposed to remain unaffected, unless explicitly specified as closed.
|
| ER-02 | The textual description of the taxiway affected portion, if provided, shall be encoded as part of the Taxiway TEMPDELTA as availability.ManoeuvringAreaAvailability.annotation and purpose='DESCRIPTION'
|
| ER-03 | First, all the BASELINE availability.ManoeuvringAreaAvailability (with operationalStatus='NORMAL'), if present, shall be copied in the Taxiway and TaxiwayElement (if applicable) 'TEMPDELTA' (see Usage limitation and closure scenarios). Then:
|
| ER-0304 | If the taxiway usage is "conditional for" specified operations, flight and/or aircraft categories, then all specified limitations shall be encoded as ManoeuvringAreaUsage child elements with type='CONDITIONAL'. |
| ER-0405 | If the taxiway is "closed, except for" specified operations, flight and/or aircraft categories, then all specified limitations shall be encoded as ManoeuvringAreaUsage child elements with type='RESERV'. |
| ER-0506 | If the taxiway usage is "prohibited for" specified operations, flight and/or aircraft categories, all specified limitations shall be encoded as ManoeuvringAreaUsage child elements with type='FORBID'. |
| ER-0607 | If the taxiway usage is "allowed for" specified operations, flight and/or aircraft categories, all specified limitations shall be encoded as ManoeuvringAreaUsage child elements with type='PERMIT'. |
| ER-0708 | 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-0809 | If PPR time is specified, the uom attribute shall also be specified. |
| ER-0910 | If the limitation concerns only 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 (with operationalStatus='LIMITED' or 'OTHER:EXTENDED') of all affected Taxiway and TaxiwayElement TEMPDELTA Timeslice(s). See the rules for Event Schedules. |
| ER-1011 | The system shall automatically identify the FIR where the AirportHeliport is located. This shall be coded as corresponding concernedAirspace property in the Event |
| ER-1112 | The AirportHeliport concerned by the closure shall also be coded as concernedAirportHeliport property in the Event. |
