Interface: TcasTcaPrediction

Defined in: src/sdk/traffic/Tcas.ts:45

A time-of-closest-approach prediction made by TCAS.

Properties​

cpaDisplacement​

readonly cpaDisplacement: ReadonlyFloat64Array

Defined in: src/sdk/traffic/Tcas.ts:65

The predicted 3D displacement vector from own airplane to this prediction's intruder at time of closest horizontal approach. Each component is expressed in units of meters.

cpaHorizontalSep​

readonly cpaHorizontalSep: NumberUnitReadOnly<Distance>

Defined in: src/sdk/traffic/Tcas.ts:71

The predicted horizontal separation between this prediction's intruder and own airplane at time of closest horizontal approach.

cpaNorm​

readonly cpaNorm: number

Defined in: src/sdk/traffic/Tcas.ts:84

The cylindrical norm of the predicted displacement vector between this prediction's intruder and own airplane at time of closest horizontal approach. A value less than or equal to 1 indicates the intruder will be inside the protected zone. Larger values correspond to greater separation.

cpaVerticalSep​

readonly cpaVerticalSep: NumberUnitReadOnly<Distance>

Defined in: src/sdk/traffic/Tcas.ts:77

The predicted vertical separation between this prediction's intruder and own airplane at time of closest horizontal approach.

isThreat​

readonly isThreat: boolean

Defined in: src/sdk/traffic/Tcas.ts:59

Whether this prediction's intruder violates the protected volume and should be considered a threat.

isValid​

readonly isValid: boolean

Defined in: src/sdk/traffic/Tcas.ts:47

Whether this prediction is valid.

tcoa​

readonly tcoa: NumberUnitReadOnly<Duration>

Defined in: src/sdk/traffic/Tcas.ts:56

The predicted time to co-altitude.

tcpa​

readonly tcpa: NumberUnitReadOnly<Duration>

Defined in: src/sdk/traffic/Tcas.ts:53

The predicted time to closest horizontal approach.

time​

readonly time: number

Defined in: src/sdk/traffic/Tcas.ts:50

The time at which this prediction was most recently updated, as a UNIX timestamp in milliseconds.
