Methods

predictDisplacement()

predictDisplacement(simTime, out): Float64Array

Defined in: src/sdk/traffic/Tcas.ts:1248

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.

Implementation of

predictSeparation()

predictSeparation(simTime, horizontalOut, verticalOut): void

Defined in: src/sdk/traffic/Tcas.ts:1258

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.
