Constructor Detail

LandingVelocityProfile

public LandingVelocityProfile(LandingSpeedSchedule spdSchedule,
                              Engine engine)

This defines the speeds desired all the way through a landing profile.

 Note:  This was changed to provide the desired speeds for the whole
        maneuver.  If you are below this speed, then you should keep
        your current speed. 

Method Detail

getLandingSpeedIasAsKnots

public double getLandingSpeedIasAsKnots()

Returns the landing speed in knots IAS.

getSpeed

public IndicatedAirspeed getSpeed(Altitude altitude)

This provides the desired speeds for the whole maneuver. If you are below this speed, then you should keep your current speed.

Parameters:

altitude - The altitude of the aircraft AGL (above ground level).

toString

public java.lang.String toString()

Overrides:
