Utility functions for working with facilities.

Constructors

Constructor

new FacilityUtils(): FacilityUtils

Returns

FacilityUtils

Methods

getLatLonFromRadialDistance()

static getLatLonFromRadialDistance(reference, radial, distance, out): GeoPoint

Defined in: src/sdk/navigation/Facilities.ts:1412

Gets latitude/longitude coordinates corresponding to a radial and distance from a reference facility.

Parameters

Parameter	Type	Description
reference	Facility	The reference facility.
radial	number	The magnetic radial, in degrees.
distance	number	The distance, in nautical miles.
out	GeoPoint	The GeoPoint object to which to write the result.

Returns

GeoPoint

The latitude/longitude coordinates corresponding to the specified radial and distance from the reference facility.

getLatLonFromRadialRadial()

static getLatLonFromRadialRadial(reference1, radial1, reference2, radial2, out): GeoPoint

Defined in: src/sdk/navigation/Facilities.ts:1430

Gets latitude/longitude coordinates corresponding to the intersection of two facility radials.

Parameters

Parameter	Type	Description
reference1	Facility	The first reference facility.
radial1	number	The first magnetic radial, in degrees.
reference2	Facility	The second reference facility.
radial2	number	The second magnetic radial, in degrees.
out	GeoPoint	The GeoPoint object to which to write the result.

Returns

GeoPoint

The latitude/longitude coordinates corresponding to the intersection of the two specified radials. If the specified radials do not intersect at a unique point, NaN is written to both lat and lon.

---

getMagVar()

static getMagVar(facility): number

Defined in: src/sdk/navigation/Facilities.ts:1395

Gets the magnetic variation at a facility, in degrees. If the facility is a VOR, the magnetic variation defined by the VOR is returned. For all other facilities, the modeled magnetic variation at the location of the facility is returned.

Parameters

Parameter	Type	Description
facility	Facility	A facility.

Returns

number

The magnetic variation at the specified facility, in degrees.

---

isFacilityType()

static isFacilityType<T>(facility, type): facility is FacilityTypeMap[T]

Defined in: src/sdk/navigation/Facilities.ts:1378

Checks whether a facility is of a given type.

Type Parameters

Type Parameter
T extends FacilityType

Parameters

Parameter	Type	Description
facility	Facility	The facility to check.
type	T	The facility type to check against.

Returns

facility is FacilityTypeMap[T]

Whether the facility is of the specified type.
