Member Function Documentation

canFlyBy()

virtual bool flightgear::RNAV::canFlyBy ( ) const

inlinevirtual

Reimplemented in GPS.

Definition at line 68 of file rnav_waypt_controller.hxx.

groundSpeedKts()

virtual double flightgear::RNAV::groundSpeedKts ( )

pure virtual

Ground speed (along the track) in knots.

Implemented in GPS.

magvarDeg()

virtual double flightgear::RNAV::magvarDeg ( )

pure virtual

Magnetic variation at current position.

Implemented in GPS.

maxFlyByTurnAngleDeg()

virtual double flightgear::RNAV::maxFlyByTurnAngleDeg ( ) const

inlinevirtual

maximum angle in degrees where flyBy is permitted.

Turns larger than this value will always be executed as fly-over to avoid a very large cut.

Reimplemented in GPS.

Definition at line 78 of file rnav_waypt_controller.hxx.

nextLegTrack()

virtual std::optional< double > flightgear::RNAV::nextLegTrack ( )

inlinevirtual

Reimplemented in GPS.

Definition at line 112 of file rnav_waypt_controller.hxx.

overflightArmAngleDeg()

virtual double flightgear::RNAV::overflightArmAngleDeg ( )

pure virtual

angle for overflight sequencing.

Implemented in GPS.

overflightArmDistanceM()

virtual double flightgear::RNAV::overflightArmDistanceM ( )

pure virtual

minimum distance to a waypoint for overflight sequencing.

Implemented in GPS.

overflightDistanceM()

virtual double flightgear::RNAV::overflightDistanceM ( )

pure virtual

minimum distance to switch next waypoint.

Implemented in GPS.

position()

virtual SGGeod flightgear::RNAV::position ( )

pure virtual

Implemented in GPS.

previousLegData()

virtual std::optional< LegData > flightgear::RNAV::previousLegData ( )

inlinevirtual

device leg previous waypoint position(eg, from route manager)

Reimplemented in GPS.

Definition at line 107 of file rnav_waypt_controller.hxx.

selectedMagCourse()

virtual double flightgear::RNAV::selectedMagCourse ( )

pure virtual

device selected course (eg, from autopilot / MCP / OBS) in degrees

Implemented in GPS.

trackDeg()

virtual double flightgear::RNAV::trackDeg ( )

pure virtual

True track in degrees.

Implemented in GPS.

turnRadiusNm() [1/2]

double flightgear::RNAV::turnRadiusNm ( )

inline

compute turn radius based on current ground-speed

Definition at line 121 of file rnav_waypt_controller.hxx.

turnRadiusNm() [2/2]

virtual double flightgear::RNAV::turnRadiusNm ( const double groundSpeedKnots )

pure virtual

compute the turn radius (based on standard rate turn) for a given ground speed in knots.

Implemented in GPS.

vspeedFPM()

virtual double flightgear::RNAV::vspeedFPM ( )

pure virtual

Vertical speed in ft/minute.

Implemented in GPS.
