Abstract. Measurements of the forward-backward production asymmetry of heavy quarks in Z decays provide a precise determination of $\sin^2\!\theta_{\rm{W,eff}}^{\rm{lept}}$ . The asymmetries are sensitive to QCD effects, in particular hard gluon radiation. In this paper QCD corrections for $A_{\mathrm{FB}}^{{b\bar{b}}}$ and $A_{\mathrm{FB}}^{{c\bar c}}$ are discussed. The interplay between the experimental techniques used to measure the asymmetries and the QCD effects is investigated using simulated events. A procedure to estimate the correction needed for experimental measurements is proposed, and some specific examples are given.
