calculateVectors

calculateVectors(legs, calculateIndex, activeLegIndex, state): void

Calculates flight path vectors for a flight plan leg.

Parameters

NameTypeDescription
legsLegDefinition[]A sequence of flight plan legs.
calculateIndexnumberThe index of the leg to calculate.

getLegMagVar

getLegMagVar(leg, point): number

Gets the magnetic variation, in degrees, to use when calculating a flight plan leg's course. If the leg defines an origin or fix VOR facility, then the magnetic variation defined at the VOR is used. Otherwise the computed magnetic variation for the specified point is used.

Parameters

NameTypeDescription
legFlightPlanLegA flight plan leg.
pointLatLonInterfaceThe location from which to get magnetic variation, if an origin VOR is not found.

Returns

number

The magnetic variation, in degrees, to use when calculating the specified flight plan leg's course.

Inherited from

TurnToFixLegCalculator.getLegMagVar

Defined in

src/sdk/flightplan/FlightPathLegCalculator.ts:81


getLegTrueCourse

getLegTrueCourse(leg, point): number

Gets the true course, in degrees, for a flight plan leg. If the leg defines an origin or fix VOR facility, then the magnetic variation defined at the VOR is used to adjust magnetic course. Otherwise the computed magnetic variation for the specified point is used.

Parameters

NameTypeDescription
legFlightPlanLegA flight plan leg.
pointLatLonInterfaceThe location from which to get magnetic variation, if an origin VOR is not found.

Returns

number

The true course, in degrees, for the flight plan leg.

Returns

undefined | GeoPoint

The geographical position corresponding to the ICAO string, or undefined if one could not be obtained.

Inherited from

getTerminatorPosition

getTerminatorPosition(leg, icao, out): undefined | GeoPoint

Gets the geographic position for a flight plan leg terminator.

Parameters
