Methods

build

▸ build(vectors, index, start, startPath, end, endPath, outboundCourse, desiredTurnRadius, desiredTurnDirection?, initialCourse?, finalCourse?, flags?, includeTurnToCourseFlag?): number

Builds a sequence of vectors representing a procedure turn from a defined starting point and initial course to a defined end point and final course. A procedure turn begins with a variable-length leg from the start point along the initial course followed by an initial turn to intercept the outbound leg of the procedure turn, then a variable-length outbound leg, a 180-degree turn, a variable-length inbound leg, and finally a turn to intercept the final course at the end point. If a full set of vectors cannot be computed given the restraints imposed by the path geometry and the desired turn radius, parts of the turn beginning with the inbound leg of the procedure turn may be altered or omitted entirely.

Parameters

Name	Type	Default value	Description
vectors	CircleVector[]	undefined	The flight path vector sequence to which to add the vectors.
index	number	undefined	The index in the sequence at which to add the vectors.
start	Readonly<Omit<Float64Array, "set" | "sort" | "copyWithin">> | LatLonInterface	undefined	The start point.
startPath	GeoCircle	undefined	The great-circle path defining the initial course.
end	Readonly<Omit<Float64Array, "set" | "sort" | "copyWithin">> | LatLonInterface	undefined	The end point.
endPath	GeoCircle	undefined	The great-circle path defining the final course.
outboundCourse	number	undefined	The true course, in degrees, of the outbound leg of the turn.
desiredTurnRadius	number	undefined	The desired turn radius, in meters.
desiredTurnDirection?	VectorTurnDirection	undefined	The desired turn direction.
initialCourse?	number	undefined	The initial course. If not defined, it will be calculated from startPath and start.
finalCourse?	number	undefined	The final course. If not defined, it will be calculated from endPath and end.
flags	FlightPathVectorFlags	FlightPathVectorFlags.CourseReversal	The flags to set on the vectors. Defaults to the CourseReversal flag.
includeTurnToCourseFlag	boolean	true	Whether to include the TurnToCourse flag on the turn vectors. True by default.

Returns

number

The number of vectors added to the sequence.
