  A study of top quark production at the future International Linear Collider,
ILC, with a centre-of-mass energy of 500 GeV is presented. The emphasis is put
on determining the sensitivity to physics beyond the Standard Model. The
analysis has been carried out with a full simulation of the ILD detector. Both,
the forward-backward asymmetry and the left-right asymmetry can be determined
to a precision of about 1% to 1.5%. The analysis points out an ambiguity which
arises in case of the production of top-quarks with left-handed helicity.
