Interface: TcasIntruder

Defined in: src/sdk/traffic/Tcas.ts:90

An intruder tracked by TCAS.

Properties

alertLevel

readonly alertLevel: Subscribable<TcasAlertLevel>

Defined in: src/sdk/traffic/Tcas.ts:95

A subscribable which provides the alert level assigned to this intruder.

---

altitude

readonly altitude: NumberUnitReadOnly<Distance>

Defined in: src/sdk/traffic/Tcas.ts:101

The altitude of this intruder at the time of the most recent update.

---

contact

readonly contact: TrafficContact

Defined in: src/sdk/traffic/Tcas.ts:92

The traffic contact associated with this intruder.

---

groundSpeed

readonly groundSpeed: NumberUnitReadOnly<Speed>

Defined in: src/sdk/traffic/Tcas.ts:107

The ground speed of this intruder at the time of the most recent update.

---

groundTrack

readonly groundTrack: number

Defined in: src/sdk/traffic/Tcas.ts:104

The true ground track of this intruder at the time of the most recent update.

---

isPredictionValid

readonly isPredictionValid: boolean

Defined in: src/sdk/traffic/Tcas.ts:134

Whether there is a valid prediction for this intruder's position and velocity.

---

position

readonly position: GeoPointReadOnly

Defined in: src/sdk/traffic/Tcas.ts:98

The position of this intruder at the time of the most recent update.

---

positionVec

readonly positionVec: ReadonlyFloat64Array

Defined in: src/sdk/traffic/Tcas.ts:119

The 3D position vector of this intruder at the time of the last update. Each component is expressed in units of meters. The coordinate system is an Euclidean approximation of the geodetic space around the own airplane such that the z-coordinate represents orthometric height and the x- and y-coordinates represent an east- counterclockwise equirectangular projection of latitude and longitude, with the origin at the location of the own airplane.

---

relativePositionVec

readonly relativePositionVec: ReadonlyFloat64Array

Defined in: src/sdk/traffic/Tcas.ts:128

The 3D position vector of this intruder relative to own airplane.

---

relativeVelocityVec

readonly relativeVelocityVec: ReadonlyFloat64Array

Defined in: src/sdk/traffic/Tcas.ts:131

The 3D velocity vector of this intruder relative to own airplane.

---

tcaRA

readonly tcaRA: TcasTcaPrediction

Defined in: src/sdk/traffic/Tcas.ts:140

A time-of-closest-approach prediction for this intruder using sensitivity settings for resolution advisories.

---

tcaTA

readonly tcaTA: TcasTcaPrediction

Defined in: src/sdk/traffic/Tcas.ts:137

A time-of-closest-approach prediction for this intruder using sensitivity settings for traffic advisories.

---

velocityVec

readonly velocityVec: ReadonlyFloat64Array

Defined in: src/sdk/traffic/Tcas.ts:125

The 3D velocity vector of this intruder at the time of the last update. Each component is expressed in units of meters per second. The coordinate system is defined the same as for position vectors.

---

verticalSpeed

readonly verticalSpeed: NumberUnitReadOnly<Speed>

Defined in: src/sdk/traffic/Tcas.ts:110

The vertical speed of this intruder at the time of the most recent update.

Methods

predictDisplacement()

predictDisplacement(simTime, out): Float64Array

Defined in: src/sdk/traffic/Tcas.ts:150

Calculates the predicted 3D displacement vector from own airplane to this intruder at a specified time based on the most recent available data. If insufficient data is available to calculate the prediction, NaN will be written to the result.

Parameters

Parameter	Type	Description
simTime	number	The sim time at which to calculate the separation, as a UNIX timestamp in milliseconds.
out	Float64Array	A Float64Array object to which to write the result.

Returns

Float64Array

The predicted displacement vector from own airplane to this intruder at the specified time.

---

predictSeparation()

predictSeparation(simTime, horizontalOut, verticalOut): void

Defined in: src/sdk/traffic/Tcas.ts:160

Calculates the predicted separation between this intruder and own airplane at a specified time based on the most recent available data and stores the results in the supplied WT_NumberUnit objects. If insufficient data is available to calculate the prediction, NaN will be written to the results.

Parameters

Parameter	Type	Description
simTime	number	The sim time at which to calculate the separation, as a UNIX timestamp in milliseconds.
horizontalOut	NumberUnit<Distance>	A NumberUnit object to which to write the horizontal separation.
verticalOut	NumberUnit<Distance>	A NumberUnit object to which to write the vertical separation.

Returns

void
