Member Function Documentation

GetAGLevel()

double GetAGLevel ( double  t, const FGLocation &  location, FGLocation &  contact, FGColumnVector3 &  normal, FGColumnVector3 &  v, FGColumnVector3 &  w  ) const

virtual

Compute the altitude above ground.

The altitude depends on time t and location l.

Parameters

t	simulation time
l	location
contact	Contact point location below the location l
normal	Normal vector at the contact point
v	Linear velocity at the contact point
w	Angular velocity at the contact point

Returns

altitude above ground

Implements FGGroundCallback.

Definition at line 57 of file FGGroundCallback.cpp.

{
  vel = FGColumnVector3(0.0, 0.0, 0.0);
  angularVel = FGColumnVector3(0.0, 0.0, 0.0);
  normal = FGColumnVector3(loc).Normalize();
  double loc_radius = loc.GetRadius();  // Get the radius of the given location
                                        // (e.g. the CG)
  double agl = loc_radius - mTerrainLevelRadius;
  contact = (mTerrainLevelRadius/loc_radius)*FGColumnVector3(loc);
  return agl;
}

GetAltitude()

double GetAltitude ( const FGLocation &  l ) const

virtual

Compute the altitude above sealevel.

Parameters

l

location

Implements FGGroundCallback.

{
  return loc.GetRadius() - mSeaLevelRadius;
}

Here is the call graph for this function:

GetSeaLevelRadius()

double GetSeaLevelRadius ( const FGLocation &  location ) const

inlinevirtual

Return the sea level radius.

Parameters

location

location

Implements FGGroundCallback.

Definition at line 173 of file FGGroundCallback.h.

   {return mSeaLevelRadius; }

GetTerrainGeoCentRadius()

double GetTerrainGeoCentRadius ( double  t, const FGLocation &  location  ) const

inlinevirtual

Compute the local terrain radius.

Parameters

t	simulation time
location	location

Implements FGGroundCallback.

Definition at line 169 of file FGGroundCallback.h.

   { return mTerrainLevelRadius; }

SetSeaLevelRadius()

void SetSeaLevelRadius ( double  radius )

inlinevirtual

Set the sea level radius.

Only needs to be implemented if JSBSim should be allowed to modify the sea level radius (see the default implementation)

Reimplemented from FGGroundCallback.

Definition at line 172 of file FGGroundCallback.h.

{ mSeaLevelRadius = radius;   }

SetTerrainGeoCentRadius()

void SetTerrainGeoCentRadius ( double  radius )

inlinevirtual

Set the local terrain radius.

Only needs to be implemented if JSBSim should be allowed to modify the local terrain radius (see the default implementation)

Reimplemented from FGGroundCallback.

Definition at line 168 of file FGGroundCallback.h.

{  mTerrainLevelRadius = radius;}
