RouteTrajectoryElementType

A portion of the route that can be at one of three levels as described below: a) A Route Element defined by a Significant Point and the ATS Route (or direct route) to be followed until a change in route. b) An Expanded Route Element defined by a Significant Point and the ATS Route (or direct route) to be followed until the next Significant Point, which may be along the same ATS Route. c)A Trajectory Element defined by a geographic point and the ATS Route (or direct route) followed until the next trajectory point. [FF-ICE/1 Implementation Guidance Manual, Appendix B, Chapter B-3.2]

alongRouteDistance

The distance along the route. For an eASP-provided expanded route, it is computed from the first converted point in the eASP's airspace for each route point in the expanded route. For an operator-provided expanded route, it is computed from the beginning of the route.

Semantic Correspondence

constraint

A number of constraints can be associated with each Expanded Route Point and Trajectory point.

elementStartPoint

A specified geographical location used in defining the flight route or expanded route. [FIXM]

enRouteDelay

En Route delay or holding planned to occur at a significant point or along a route element.

Semantic Correspondence

extension

An extension hook for attaching extension (non-core) classes.

Semantic Correspondence

flightRulesChange

Describes the planned change of flight rules (e.g., IFR/VFR) associated with a route point.

Semantic Correspondence

modified

Identifies if the route point or element was modified from the reference version, identified in the message, during negotiation by an ASP.

modifiedRouteItemReference

A reference to an ATFM program name that modified the route.

Semantic Correspondence

point4D

Identifies the location, altitude and time of a trajectory point.

routeDesignatorToNextElement

The route (airway) to the next element on the route. Can be either an en route airway, standard instrument departure route, or standard instrument arrival route. [FIXM]

seqNum

Incrementing identifier used to ensure the sequence of ordered lists is retained. The identifier should begin at zero. [FIXM]
