Methods
lnavInterceptCurve()
staticlnavInterceptCurve(dtk,xtk,tas):number
Defined in: workingtitle-instruments-wt21/instruments/html_ui/Pages/VCockpit/Instruments/WT21v2/FMC/Autopilot/WT21APUtils.ts:34
Calculates intercept angles for LNAV.
Parameters
| Parameter | Type | Description |
|---|---|---|
dtk | number | The desired track, in degrees true. |
xtk | number | The cross-track error, in nautical miles. Negative values indicate that the plane is to the left of the desired track. |
tas | number | The true airspeed of the plane, in knots. |
Returns
number
The intercept angle, in degrees, to capture the desired track from the navigation signal.
localizerInterceptCurve()
staticlocalizerInterceptCurve(deflection,xtk,tas):number
Defined in: workingtitle-instruments-wt21/instruments/html_ui/Pages/VCockpit/Instruments/WT21v2/FMC/Autopilot/WT21APUtils.ts:47
Calculates intercept angles for localizers.
Parameters
| Parameter | Type | Description |
|---|---|---|
deflection | number | The lateral deflection of the desired track relative to the plane, normalized from -1 to 1. Negative values indicate that the desired track is to the left of the plane. |
xtk | number | The cross-track error of the plane from the desired track, in nautical miles. Positive values indicate indicate that the plane is to the right of the track. |
tas | number | The true airspeed of the plane, in knots. |
Returns
number
The intercept angle, in degrees, to capture the localizer course.
navInterceptCurve()
staticnavInterceptCurve(distanceToSource,deflection,xtk,tas,isLoc?):number
Defined in: workingtitle-instruments-wt21/instruments/html_ui/Pages/VCockpit/Instruments/WT21v2/FMC/Autopilot/WT21APUtils.ts:18
Calculates intercept angles for radio nav.
Parameters
| Parameter | Type | Description |
|---|---|---|
distanceToSource | number | The distance from the plane to the source of the navigation signal, in nautical miles. |
deflection | number | The lateral deflection of the desired track relative to the plane, normalized from -1 to 1. Positive values indicate that the desired track is to the right of the plane. |
xtk | number | The cross-track error of the plane from the desired track, in nautical miles. Positive values indicate indicate that the plane is to the right of the track. |
tas | number | The true airspeed of the plane, in knots. |
isLoc? | boolean | Whether the source of the navigation signal is a localizer. Defaults to false. |
Returns
number
The intercept angle, in degrees, to capture the desired track from the navigation signal.
