getLegMagVar()

Call Signature

protected getLegMagVar(leg): number | undefined

Defined in: src/sdk/flightplan/flightpath/legcalculators/AbstractFlightPathLegCalculator.ts:134

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 database magnetic variation defined for the VOR is used (the origin facility takes priority).

Parameters

Parameter	Type	Description
leg	FlightPlanLeg	A flight plan leg.

Returns

number | undefined

The magnetic variation, in degrees, to use when calculating the specified flight plan leg's course, or undefined if the leg does not define an origin or fix VOR facility.

Inherited from

TurnToFixLegCalculator.getLegMagVar

Call Signature

protected getLegMagVar(leg, defaultPoint): number

Defined in: src/sdk/flightplan/flightpath/legcalculators/AbstractFlightPathLegCalculator.ts:143

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 database magnetic variation defined for the VOR is used (the origin facility takes priority). Otherwise, the model magnetic variation for the specified point is used.

Parameters

Parameter	Type	Description
leg	FlightPlanLeg	A flight plan leg.
defaultPoint	LatLonInterface	The location from which to get magnetic variation if an origin or fix VOR is not found.

Returns

number

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

Call Signature

protected getLegMagVar(leg, defaultPoint?): number | undefined

Defined in: src/sdk/flightplan/flightpath/legcalculators/AbstractFlightPathLegCalculator.ts:153

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 database magnetic variation defined for the VOR is used (the origin facility takes priority). Otherwise, the model magnetic variation for the specified point, if defined, is used.

Parameters

Parameter	Type	Description
leg	FlightPlanLeg	A flight plan leg.
defaultPoint?	LatLonInterface	The location from which to get magnetic variation if an origin or fix VOR is not found.

Returns

number | undefined

The magnetic variation, in degrees, to use when calculating the specified flight plan leg's course, or undefined if the leg does not define an origin or fix VOR facility and a default point was not provided.

getLegTrueCourse()

protected getLegTrueCourse(leg): number | undefined

Defined in: src/sdk/flightplan/flightpath/legcalculators/AbstractFlightPathLegCalculator.ts:175

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.

Returns

number | undefined

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

protected getMagVarFromIcao(icao): number | undefined

Defined in: src/sdk/flightplan/flightpath/legcalculators/AbstractFlightPathLegCalculator.ts:52

Gets the magnetic variation, in degrees, at a facility. If the facility is a VOR and it has a nominal database magnetic variation, then that value will be returned. Otherwise, the model magnetic variation at the facility's position will be returned.

Parameters
