f) Aerodrome / Heliport

Due to the extent of the AIXM 5 diagrams, the mapping of the PANS-AIM "Aerodrome/Heliport" subject is divided into several parts.

The first part contains the basic mapping, i.e. those properties that are listed in PANS-AIM Chapter 5.3.3.1.1 "AIP Data set" and are hence considered as the minimum data set to be provided. These are

f) Aerodrome/Heliport (location indicator, name, designator IATA, served city, certified ICAO, certification date, certification expiration date, control type, field elevation, reference temperature, magnetic variation, airport reference point);

The other parts contain the mapping for the additional data items identified to be required for the AIP data set.

Basic mapping

The properties of the Aerodrome / Heliport subject listed in PANS-AIM are mapped to the following main AIXM 5 feature:

AirportHeliport

PANS-AIM	Description (PANS-AIM)	AIXM 5	Remarks
Designator - ICAO location indicator	The four letter ICAO location indicator of the aerodrome/heliport, as listed in ICAO DOC 7910 (Location Indicators). Note: if any	AirportHeliport.locationIndicatorICAO, AirportHeliport.designator	Proposal for Verification Rule The rules according to which this identifier should be formed are as follows: 1. If the Aerodrome/Heliport has an ICAO four letter location indicator, then this one will become the designator for the Aerodrome/Heliport; 2. If the Aerodrome/Heliport does not have an ICAO four letter location indicator, but it has an IATA three letter code, then this one will become the designator for the Aerodrome/Heliport; 3. If the Aerodrome/Heliport has neither an ICAO four letter location indicator nor an IATA three letter code, then an artificial generated code will be used. This will contain a group of letters and a number. The group of letters could be the 2 letter code of the State being responsible for the Aerodrome/Heliport and the number could be an integer between 0001 and 9999. PANS-AIM naming issue In PANS-AIM chapter 5.3.3.1.1 the term "location indicator" is used. In Appendix 1 the term "ICAO location indicator" is used.
Designator - Designator IATA	The identifier that is assigned to a location in accordance with rules (resolution 767) governed by the International Air Transport Association (IATA). Note: if any	AirportHeliport.designatorIATA, AirportHeliport.designator
Designator - Other	A locally defined airport identifier, if other than an ICAO Location Indicator	AirportHeliport.designator	Although this is an optional property, it is mapped for the sake of the proposed verification rule (see above).
Name	The primary official name of an aerodrome as designated by an appropriate authority.	AirportHeliport.name
Served city	The full name ( free text) of the city or town the aerodrome/heliport is serving.	AirportHeliport.servedCity.City.name
Control type	Indication if an aerodrome is under civil control, military control or joint control	AirportHeliport.controlType
Certified ICAO	Indication if airport is/is not certified according to the ICAO rules	AirportHeliport.certifiedICAO
Certification date	The date when the airport certification has been issued by the supervising authority.	AirportHeliport.certificationDate
Certification experation date	The date when the airport certification will become invalid.	AirportHeliport.certificationExpirationDate
Field elevation - Elevation	The vertical distance above Mean Sea Level (MSL) of the highest point of the landing area.	AirportHeliport.fieldElevation AirportHeliport.fieldElevationAccuracy
Field elevation - Geoid undulation	Geoid undulation at the aerodrome/ heliport elevation position Note: where appropriate	AirportHeliport.annotation.Note.propertyName equal-to 'fieldElevation' .translatedNote.LinguisticNote.note	AIXM issue In AIXM 5.1.(1) the geoidUndulation can only be provided for the ARP (i.e ElevatedPoint), which may not be the highest point of the landing area. An annotation for the property fieldElevation of the AirportHeliport may be used to encode that information including the accuracy of the Geoid Undulation.
Reference temperature	The monthly mean of the daily maximum temperatures for the hottest month of the year at an aerodrome. This temperature should be averaged over a period of years. (ICAO recommendation)	AirportHeliport.referenceTemperature
Magnetic variation - Angle	The angular difference between True North and Magnetic North. The magnetic variation angle value	AirportHeliport.magneticVariation	AIXM 5.1.1 issue PANS-AIM requires an Accuracy for the Magnetic variation - Angle. AIXM 5.1.1 does not provide a dedicated attribute. Note may be used to code that information.
Magnetic variation - Date	The date on which the magnetic variation had the corresponding value.	AirportHeliport.dateMagneticVariation
Magnetic variation - Annual change	The annual rate of change of the magnetic variation.	AirportHeliport.magneticVariationChange
Airport reference point - Position	The designated geographical location of an aerodrome. Geographical location of aerodrome reference point.	AirportHeliport.ARP.ElevatedPoint AirportHeliport.ARP.ElevatedPoint.horizonalAccuracy	PANS-AIM naming issue In PANS-AIM chapter 5.3.3.1.1 the term "airport reference point" is used. In Appendix 1 the term "reference point" is used.
Airport reference point - Site	The location of the reference point on the aerodrome.	AirportHeliport.annotation.Note.propertyName equal-to 'ARP' .translatedNote.LinguisticNote.note	AIXM issue There is no dedicated attribute in AIXM 5.1.1 to encode that information. An annotation to the ARP property of AirportHeliport feature may be used.
Airport reference point - Direction	Direction of aerodrome reference point from centre of the city or town which the aerodrome serves	AirportHeliport.annotation.Note.propertyName equal-to ''ARP' .translatedNote.LinguisticNote.note	AIXM issue There is no dedicated attribute in AIXM 5.1.1 to encode that information. An annotation to the ARP property of AirportHeliport feature may be used.
Airport reference point - Distance	Distance of aerodrome reference point from centre of the city or town which the aerodrome serves	AirportHeliport.annotation.Note.propertyName equal-to 'ARP' .translatedNote.LinguisticNote.note	AIXM issue There is no dedicated attribute in AIXM 5.1.1 to encode that information. An annotation to the ARP property of AirportHeliport feature may be used.

Additional mapping (Type of Traffic Permitted)

The Type of Traffic permitted as defined in the PANS-AIM is covered in AIXM by the AirportHeliportAvailability and its related objects.

Description (PANS-AIM)

AIXM 5

Remarks

Type of Traffic Permitted - IFR/VFR

Indication if IFR and/or VFR flights are permitted at the aerodrome/heliport

AirportHeliport.availability.AirportHeliportAvailability.usage.AirportHeliportUsage

.selection.ConditionCombination.flight.FlightCharacteristic.rule

The ARINC 424 Airport Record (PA) contains a field named "IFR Capability".

The IFR Capability field indicates if the Airport/Heliport has any published Instrument Approach Procedures (IAP).

The assumption is made that for an AirportHeliport IFR traffic is permitted also IAP are published. If no IFR procedure is published it is considered to be a VFR airport.
