Interface: TcasIntruder

An intruder tracked by TCAS.

Implemented by​

Properties​

alertLevel​

• Readonly alertLevel: Subscribable<TcasAlertLevel>

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

Defined in​

src/sdk/traffic/Tcas.ts:95

altitude​

• Readonly altitude: NumberUnitReadOnly<Distance, Unit<Distance>>

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

Defined in​

src/sdk/traffic/Tcas.ts:101

contact​

• Readonly contact: TrafficContact

The traffic contact associated with this intruder.

Defined in​

src/sdk/traffic/Tcas.ts:92

groundSpeed​

• Readonly groundSpeed: NumberUnitReadOnly<Speed, Unit<Speed>>

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

Defined in​

src/sdk/traffic/Tcas.ts:107

groundTrack​

• Readonly groundTrack: number

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

Defined in​

src/sdk/traffic/Tcas.ts:104

isPredictionValid​

• Readonly isPredictionValid: boolean

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

Defined in​

src/sdk/traffic/Tcas.ts:134

position​

• Readonly position: GeoPointReadOnly

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

Defined in​

src/sdk/traffic/Tcas.ts:98

positionVec​

• Readonly positionVec: Readonly<Omit<Float64Array, "set" | "sort" | "copyWithin">>

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.

Defined in​

src/sdk/traffic/Tcas.ts:119

relativePositionVec​

• Readonly relativePositionVec: Readonly<Omit<Float64Array, "set" | "sort" | "copyWithin">>

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

Defined in​

src/sdk/traffic/Tcas.ts:128

relativeVelocityVec​

• Readonly relativeVelocityVec: Readonly<Omit<Float64Array, "set" | "sort" | "copyWithin">>

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

Defined in​

src/sdk/traffic/Tcas.ts:131

tcaRA​

• Readonly tcaRA: TcasTcaPrediction

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

Defined in​

src/sdk/traffic/Tcas.ts:140

tcaTA​

• Readonly tcaTA: TcasTcaPrediction

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

Defined in​

src/sdk/traffic/Tcas.ts:137

velocityVec​

• Readonly velocityVec: Readonly<Omit<Float64Array, "set" | "sort" | "copyWithin">>

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.

Defined in​

src/sdk/traffic/Tcas.ts:125

verticalSpeed​

• Readonly verticalSpeed: NumberUnitReadOnly<Speed, Unit<Speed>>

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

Defined in​

src/sdk/traffic/Tcas.ts:110

Methods​

predictDisplacement​

▸ predictDisplacement(simTime, out): Float64Array

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​

NameTypeDescription
simTimenumberThe sim time at which to calculate the separation, as a UNIX timestamp in milliseconds.
outFloat64ArrayA Float64Array object to which to write the result.

Returns​

Float64Array

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

Defined in​

src/sdk/traffic/Tcas.ts:150

predictSeparation​

▸ predictSeparation(simTime, horizontalOut, verticalOut): void

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​

NameTypeDescription
simTimenumberThe sim time at which to calculate the separation, as a UNIX timestamp in milliseconds.
horizontalOutNumberUnit<Distance, Unit<Distance>>A NumberUnit object to which to write the horizontal separation.
verticalOutNumberUnit<Distance, Unit<Distance>>A NumberUnit object to which to write the vertical separation.

Returns​

void
