com.luciad.ais.model.procedure.TLcdAircraftState

public class TLcdAircraftState
extends Object

Represents the current state of the aircraft flying a procedure. The state consists of position, course and altitude. The position can be flagged as invalid when the geometry calculator finds itself in a situation it can't handle properly. The state also includes the aircraft's performance characteristics, such as the climb rate and the turn radius.

Constructor Detail

TLcdAircraftState

public TLcdAircraftState()

Default constructor. Marks the current state as invalid and sets default values for the aircraft performance settings.

Method Detail

getCurrentPosition

public ILcdPoint getCurrentPosition()

Returns the current position of the aircraft. Do not use the returned coordinates if the state is not valid!

Returns:

the current position of the aircraft

getCurrentCourse

public double getCurrentCourse()

Returns the current course of the aircraft. The return value may be NaN if the course is currently invalid.

Returns:

the current course of the aircraft

getCurrentAltitude

public double getCurrentAltitude()

Returns the current altitude of the aircraft. The return value may be NaN if the altitude is currently invalid.

Returns:

the current altitude of the aircraft

invalidate

public void invalidate()

Invalidates the current state. This will result in the position being moved to the origin, and the course and altitude being set to NaN.

isStateValid

public boolean isStateValid()

Indicates whether or not the current state is valid. Position, course and altitude should not be used if this returns false.

Returns:

a boolean indicating whether or not the current state is valid

setCurrentPosition

public void setCurrentPosition(ILcdPoint aPos)

Moves the current position to the specified location.

Parameters:

aPos - the new aircraft position

setCurrentCourse

public void setCurrentCourse(double aCourse)

Sets the current course to the specified value. Set to NaN to indicate that the current course is unknown.

Parameters:

aCourse - the new course

setCurrentAltitude

public void setCurrentAltitude(double aAltitude)

Sets the current altitude to the specified value. Set to NaN to indicate that the current altitude is unknown.

Parameters:

aAltitude - the new altitude

getAircraftPerformanceSettings

public TLcdAircraftPerformanceSettings getAircraftPerformanceSettings()

Returns the current aircraft performance settings.

Returns:

an TLcdAircraftPerformanceSettings

setAircraftPerformanceSettings

public void setAircraftPerformanceSettings(TLcdAircraftPerformanceSettings aPerformanceSettings)

Sets the current aircraft performance settings.

Parameters:

aPerformanceSettings - an TLcdAircraftPerformanceSettings
