Ok let's forget the circle for now until I understand what the goal is.
I attached a small graphic.
Assuming the plane is in A and the target in B: Is the carrot on the actual 
course (Heading line)(carrot A) or on the wanted course (=Bearing or Course 
line) (carrot W) or on the real route (carrot R) whatever real route would 
mean?
I don't understand why you would compute this carrot position:
        - Computing the wanted heading to carrot W or directly to target B 
doesn't 
really make a difference does it ?
        - Does knowig the location of carrot 1 helps in anything ?
        - How would you compute the carrot on the real route ? Can you predict 
what 
it's going to be ?

Thanks
