Detailed Description

Controller supports 'directTo' (DTO) navigation to a waypoint.

This creates a course from a starting point, to the waypoint, and reports deviation from that course.

The controller is done when the waypoint is reached (to/from goes to 'from')

◆ courseDeviationDeg()

double flightgear::DirectToController::courseDeviationDeg ( ) const

virtual

Reimplemented from flightgear::WayptController.

Definition at line 1395 of file rnav_waypt_controller.cxx.

◆ distanceToWayptM()

double flightgear::DirectToController::distanceToWayptM ( ) const

virtual

Compute distance until the waypoint is done.

Implements flightgear::WayptController.

◆ init()

bool flightgear::DirectToController::init ( )

overridevirtual

Reimplemented from flightgear::WayptController.

Definition at line 1344 of file rnav_waypt_controller.cxx.

◆ position()

SGGeod flightgear::DirectToController::position ( ) const

virtual

Position associated with the waypt.

For static waypoints, this is simply the waypoint position itself; for dynamic points, it's the estimated location at which the controller will be done.

Implements flightgear::WayptController.
