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.
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.
getTerminatorPosition()
protected
getTerminatorPosition(leg
,icao
,out
):undefined
|GeoPoint
Defined in: src/sdk/flightplan/FlightPathLegCalculator.ts:64
Gets the geographic position for a flight plan leg terminator.
Parameters
Parameter | Type | Description |
---|---|---|
leg | FlightPlanLeg | A flight plan leg. |
icao | string | The ICAO string of the leg's terminator fix. |
out | GeoPoint | A GeoPoint object to which to write the result. |
Returns
undefined
| GeoPoint
The position of the leg terminator, or undefined if it could not be determined.
