getLegMagVar()

protected getLegMagVar(leg, point): number

Defined in: src/sdk/flightplan/FlightPathLegCalculator.ts:81

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

Parameter	Type	Description
leg	FlightPlanLeg	A flight plan leg.
point	LatLonInterface	The 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

AbstractFlightPathLegCalculator.getLegMagVar

---

getLegTrueCourse()

protected getLegTrueCourse(leg, point): number

Defined in: src/sdk/flightplan/FlightPathLegCalculator.ts:100

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

Parameter	Type	Description
leg	FlightPlanLeg	A flight plan leg.
point	LatLonInterface	The 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.

getPositionFromIcao()

protected getPositionFromIcao(icao, out): undefined | GeoPoint

Defined in: src/sdk/flightplan/FlightPathLegCalculator.ts:52

Gets a geographical position from an ICAO string.

Parameters

Parameter	Type	Description
icao	string	An ICAO string.
out	GeoPoint	A GeoPoint object to which to write the result.

Returns

undefined | GeoPoint

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

Inherited from

AbstractFlightPathLegCalculator.getPositionFromIcao

---

getTerminatorPosition()

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

Defined in: src/sdk/flightplan/FlightPathLegCalculator.ts:64

Parameters

Parameter	Type	Description
leg	FlightPlanLeg	A flight plan leg.
icao	string	The ICAO string of the leg's terminator fix.
