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
| Name | 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

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
| Name | 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.

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.
