Hi Gary ... Ive wondered about this myself.
Found this section in YASim/Surface.cpp :
// Similar to the above -- interpolates out the flap lift past the
// stall alpha
float Surface::flapLift(float alpha)
{
float flapLift = _cz * _flapPos * (_flapLift-1) * _flapEffectiveness;
Hopefully Andy can explain it in layman's term :)
Cheers
