Route - AIXM Coding Checklist

The following table provided a complete overview of the AIXM 5 features/objects and properties relevant for the coding of route which will be published as part of an PANS-AIM defined AIP data set.

The table also gives an indication if the property is mandatory for an AIP data set and under which conditions.

AIXM Feature/Object	AIXM Feature/Object Property	Complex Type or xlink:href to other Feature	AIP data set
Route	designatorPrefix		Mandatory, if applicable
	designatorSecondLetter		Mandatory
	designatorNumber		Mandatory
	multipleIdentifier		Mandatory, if applicable
	locationDesignator		Optional
	name		Optional
	type		Optional
	flightRule		Acc. to PANS-AIM only relevant for "Other routes".
	internationalUse		Optional
	militaryUse		Optional
	militaryTrainingType		Optional
	userOrganisation	xlink:href -> OrganisationAuthority	Optional
	annotation	Note	Optional
RouteSegment	level		Optional The level of a route segment (Upper, lower or both) is not part of the PANS-AIM chapter 5.3.3.1.1 nor Appendix 1 (Aeronautical Data Catalogue) nor of Appendix 2. However, it is part of the coding guidelines as it is contained in the ARINC 424 Enroute Airways Records (ER); data field is named "Level (LEVEL)".
	upperLimit		Mandatory
	upperLimitReference		Mandatory
	lowerLimit		Mandatory
	lowerLimitReference		Mandatory
	minimumObstacleClearanceAltitude		Mandatory for ENR 3.1 Lower ATS Routes.
	pathType		Optional However, according to PANS-AIM ENR 3 the pathType shall be the geodesic distance.
	trueTrack		Mandatory or magneticTrack coded
	magneticTrack		Mandatory or trueTrack to be coded
	reverseTrueTrack		Mandatory, if applicable
	reverseMagneticTrack		Mandatory, if applicable
	length		Mandatory
	widthLeft		Mandatory for ENR 3.1 Lower ATS Routes and ENR 3.2 Upper ATS Routes.
	widthRight		Mandatory for ENR 3.1 Lower ATS Routes and ENR 3.2 Upper ATS Routes.
	turnDirection		Optional
	signalGap		Optional
	minimumEnrouteAltitude		Mandatory for ENR 3.1 Lower ATS Routes.
	minimumCrossingAtEnd		Optional
	minimumCrossingAtEndReference		Optional
	maximumCrossingAtEnd		Optional
	maximumCrossingAtEndReference		Optional
	navigationType		Mandatory In general there seems to be issues regarding the modelling of the navigation specification for routes in AIXM and PANS-AIM. Issues: The PANS-AIM description is not clear in regard what is required. Just to specify if the route is an RNP or RNAV route or the specific RNP/RNAV specification, e.g. RNP 4 or RNAV 5? The navigationType attribute of AIXM only provides as values 'RNAV', 'CONV' and 'TACAN'. Using 'OTHER' may be used to define that it is a RNP., i.e. 'OTHER:RNP'. AIXM provides a dedicated attribute for the requiredNavigationPerformance that can be used to code specific RNP values e.g.: '5' or'4'. PANS-AIM in addition to this property also defines a "Navigation performance requirements" property. Recommendation to review both the PANS-AIM properties and descriptions and the AIXM concept for the navigation specification for Route.
